Description

MODULES AND FUSE CIRCUIT BREAKER DEVICES CROSS REFERENCE WITH RELATED APPLICATIONS This application is a continuation request in part of the United States Application Serial No. 11 / 222,628 entitled Modules and Fuse Circuit Breakers and filed on September 9, 2005, claiming the benefit of the Request Provisional of the United States Series No. 60 / 609,431 filed on September 13, 2004, whose full disclosure is considered part of this, as a reference.

BACKGROUND OF THE INVENTION This invention relates generally to fuses, and more particularly, to circuit breakers utilizing fuses. Fuses are widely used as overcurrent protection devices to prevent costly damage to electrical circuits. Terminals with fuses typically form an electrical connection between a source of electrical power and an electrical component or a combination of components configured in an electrical circuit. One or more slats or fusible elements, or an assembly of fusible elements, are connected between the Fuse terminals, so that when the electric current passing through the fuse exceeds a predetermined limit, the fuse elements melt and open one or more circuits through the fuse to prevent damage to electrical components. In some applications, fuses are used not only to provide electrical connections with fuses but also for connection and disconnection, or switching, for purposes of completing or interrupting a connection or electrical connections. As such, an electrical circuit is completed or interrupted through conductive portions of the fuse, thereby energizing or deenergizing the associated circuitry. Typically, the fuse is housed in a fuseholder having terminals that are electrically coupled to the desired circuitry. When the conductive portions of the fuse, such as fuse blades, terminals or bushes, are coupled to the terminals of the fuse holder, an electrical circuit is completed through the fuse, and when the conductive portions of the fuse are decoupled from the terminals of the fuse holder, the electrical circuit through the fuse is interrupted. Therefore, when inserting and removing the fuse to and from the terminals of the fuse holder, a commutation is performed to disconnect the fuses.

DETAILED DESCRIPTION OF THE INVENTION The known fuse switches experience various problems during use. For example, any attempt to remove the fuse while the fuses are energized and under load can result in hazardous conditions because dangerous arcing can occur between the fuses and the terminals of the fuse holder. Some fuse holders designed to accommodate, for example, Class CC fuses of the Underwriters Laboratories (UL) standardization entity and the 10X38 fuses of the International Electrotechnical Commission (IEC) that are commonly used in industrial control devices include contacts permanently mounted auxiliaries and associated rotating cams and switches to produce "delayed" and "anticipated" current and voltage connections through the fuses, when these are removed from the fuse clamps in a protective housing. One or more fuses can be removed from the fuse clamps, for example, by removing a drawer from the protective housing. Connections that anticipate disconnection and delay re-connection are commonly used, for example, in motor control applications. Since connections that anticipate disconnection and delay re-connection can increase the safety of such devices for users when fuses are installed and removed, such features increase costs, complicate the fuseholder assembly, and are undesirable for switching. Structurally, advance connections on disconnection and connection delay can be intricate and can not withstand repeated use for switching purposes. In addition, when the extractor is opened and closed to disconnect or reconnect the circuitry, the extractor may be left unintentionally in a partially open or partially closed position. In any case, the fuses in the extractor they may not be fully coupled to the terminals of the fuses, thereby compromising the electrical connection and the fuse holder becomes susceptible to unintentional opening and closing of the circuit. Especially in environments subjected to vibration, the fuses can be released with shaking of the clamps. Furthermore, a partially open extractor protruding from the fuseholder may interfere with the work space around the fuseholder. Workers can unintentionally collide in open extractors, and maybe involuntarily close the extractor and re-energize the circuit. Additionally, in certain systems, such as industrial control devices, electrical equipment has become standardized in size and form, and because switching circuit breakers using known fuses tend to vary from standard standards in size and form, these are not necessarily compatible with power distribution panels used with such equipment. For at least the above reasons, the use of fuse circuit breakers has not fully met the needs of certain final applications. Figure 1 is a perspective view of an exemplary fuse breaker device (100) that overcomes the aforementioned difficulties. The fuse circuit breaker (100) can conveniently turn on and off in a safe and proper manner, without interfering with the workspace around the device (100). The circuit breaker device 100 can reliably turn on and off a circuit in a cheap manner and can be used with standardized equipment, for example in industrial control applications. In addition, the circuit breaker device (100) may be provided with several connection and mounting options for versatility in the field. Next, various embodiments will be described to demonstrate the versatility of the circuit breaker device, and it is considered that the circuit breaker device 100 can be beneficial in a range of electrical circuits and applications. The modalities set forth below are therefore provided for illustrative purposes only, and the invention is not intended to be limited to any specific modality or to any specific application. In the illustrative embodiment of Figure 1, the circuit breaker device (100) can be a bipolar device, formed of two separate disconnection modules (102). Each module (102) may include an insulating housing (104), a fuse (106) loaded in the housing (104), a cover or fuse cover (108) connecting the fuse to the housing (104), and a switch actuator (110). The modules (102) are single-pole modules, and the modules (102) may be coupled or configured in series to form the bipolar circuit breaker (100). However, it is considered that a multi-pole device could be formed in a simple housing instead of the modular manner of the exemplary embodiment shown in Figure 1. The housing (104) can be made of an insulating or non-conductive material, such as plastic, according to known methods and techniques, including without restriction the techniques of injection molding. In an exemplary embodiment, the housing (104) is formed in a generally rectangular size and shape that is complementary and compatible with the standards of the German Standards Institute (DIN) and the International Electrotechnical Commission (IEC). for its acronym in English) applicable to standardized electrical equipment. In particular, for example, each housing (104) has a lower edge (112), opposite side edges (114), side panels (116) extending between the side edges (114), and an upper surface (118) that is extends between the side edges (114) and the side panels (116). The lower edge (112) has a length L and the side edges (114) have a thickness T, such as 17.5 mm in one embodiment, and the length L and the thickness T define an area or footprint in the lower edge (112) of the housing (104). The imprint allows the lower edge 112 to be inserted into a standardized opening having a complementary shape and dimension. Additionally, the side edges (114) of the housing (104) have a height H according to known standards, and the side edges (114) include grooves (120) extending therethrough to vent the housing (104). The upper surface (118) of the housing (104) may be contoured to include a raised central portion (122) and recessed end portions (124) that extend to the side edges (114) of the housing (104). The fuse (106) of each module (102) can be loaded vertically into the housing (104) through an opening in the upper surface (118) of the housing (104), and the fuse (106) can be partially extended to through the elevated central portion (122) of the upper surface (118). The fuse cover (108) extends over the exposed portion of the fuse (106) extending from the housing (104), and the cover (108) secures the fuse (106) to the housing (104) in each module (102). In an exemplary mode, the cover (108) may be made of a non-conductive material, such as plastic, and may be formed with a flat or generally flat end section (126) and elongate fingers (128) extending between the upper surface (118) of the raised central portion (122) of the housing (104) and the end of the fuse (106). Openings are provided between the adjacent fingers (128) to vent the end of the fuse (106). In an exemplary embodiment, the cover (108) further includes edge sections (130) that attach the fingers (128) opposite the end section (126) of the cover (108), and the edge sections (130) ensure the cover (108) to the housing (104). In an exemplary embodiment, the edge sections (130) cooperate with notches in the housing (104) such that the cover (108) can rotate a predetermined amount, such as 25 degrees, between a secured position and a released position. That is, once the fuse (106) is inserted into the housing (104), the fuse cover (108) can be installed over the end of the fuse (106) inside the notch in the housing (104), and the cover (108) can be turned 25 degrees to the secured position, where the cover (108) will prevent removal of the fuse (106) from the housing (104). The notch may also be in the form of a ramp or inclined so that the cover (108) applies a slightly downward force on the fuse (106) as the cover (108) is installed. To remove the fuse (106), the cover (108) can be rotated from the secured position to the open position, where both the cover (108) and the fuse (106) can be removed from the housing (104). The switch actuator (110) may be located in an opening (132) of the raised upper surface (122) of the housing (104), and the switch actuator (110) may extend partially through the raised upper surface (122). ) of accommodation (104). The switch actuator (100) may be rotatably mounted to the housing (104) in a shaft or shaft (134) within the housing (104), and the switch actuator (110) may include a lever, handle or bar (136) which extends radially from the actuator (110). By moving the lever (136) from a first edge (138) to a second edge (140) of the opening (132), the shaft (134) rotates to an open or commutated position and electrically disconnects the fuse (106) at each module (102) Co or it is explained right away. When the lever (136) moves from the second edge (140) towards the first edge (138), the shaft (134) rotates back to the closed position illustrated in Figure 1 and electrically connects the fuse (106). A terminal element on the side of the line (142) may extend from the lower edge (112) of the housing (104) in each module (102) to establish the line and load connections to the circuitry. As shown in Figure 1, the terminal element on the line side (142) is a busbar clamp configured or adapted to be connected to a line input bus, although it is considered that other terminal elements on the side of the bus line could be used in alternative modes. A panel mounting clip (144) also extends from the lower edge (112) of the housing (104) to facilitate mounting of the circuit breaker (100) in a panel. Figure 2 is a side elevational view of one of the disconnection modules (102) shown in Figure 1 with the side panel (116) removed. The fuse (106) may be located in a compartment (150) within the housing (104). In an exemplary embodiment, the fuse (106) may be a fuse of cylindrical cartridge including an insulating cylindrical body (152), ferrules or conductive end caps (154) coupled to each end of the body (152), and a fuse element or fuse element assembly extending within the body (152) ) and which is electrically connected to the end caps (154). In exemplary embodiments, the fuse (106) may be a UL-class fuse CC, a supplementary fuse UL, or 10X38 IEC fuses commonly used in industrial control applications. These and other types of cartridge fuses, suitable for use in the module (102) are commercially available from Cooper / Bussmann of St. Louis, Missouri. It is understood that other types of fuses can also be used in the module (102), as desired. One terminal of the lower conductor fuse (156) can be located in a lower portion of the fuse compartment (150) and can be in the form of U in one modality. One end cap (154) of the fuse (106) is supported on an upper leg (158) of the lower terminal (156), and the other end cap (154) of the fuse (106) is coupled to a terminal upper (160) located in the housing (104) adjacent to the fuse compartment (150). The upper terminal (160) is, in turn, connected to a terminal on the load side (162) to accept a load side connection to the circuit breaker module (102) in a known manner. The load side terminal (162) in one embodiment is a known support screw terminal, although it is evident that other types of terminals could be used for connections on the load side to the module (102). Additionally, the lower fuse terminal (156) may include fuse reject features in a further mode, which prevent the installation of incorrect fuse types in the module (102). The switch actuator (110) may be located in an actuator compartment (164) within the housing (104) and may include the shaft (134), a rounded body (166) that extends generally radially from the shaft (134) , the lever (136) extends from the body (166), and a linkage of the actuator (168) coupled to the body of the actuator (166). The linkage of the actuator (168) may be connected to a spring-loaded contact assembly (170) including first and second movable or switchable contacts (172) and (174) coupled to a slide bar (176). In the closed position illustrated in Figure 2, the switchable contacts (172) and (174) are mechanically and electrically coupled to the stationary contacts (178) and (180) mounted in the housing (104). One of the stationary contacts (178) may be mounted to one end of the terminal element (142), and the other of the stationary contacts (180) may be mounted to one end of the lower fuse terminal (156). When the switchable contacts (172) and (174) are coupled to the stationary contacts (178) and (180), a circuit is completed by path through the fuse (106) from the line terminal (142) and the terminal of the bottom fuse (156) towards the upper fuse terminal (160) and the load terminal (162). While in an exemplary embodiment the stationary contact (178) is mounted to a terminal (142) having a bus bar clamp, another terminal element, such as a known box lug or clamp terminal could be provided in a compartment ( 182) in the housing (104) in place of the bus bar clamp. Thus, the module (102) can be used with a wired connection to the line side circuitry instead of a line input bus. In this way, the module (102) is easily convertible into different mounting options in the field. When the switch actuator (110) is rotates around the shaft (134) in the direction of the arrow A, the slide bar (176) can move linearly upwards in the direction of the arrow B to decouple the switchable contacts (172) and (174) from the stationary contacts (178) and (180). The lower fuse terminal (156) is then disconnected from the terminal element on the line side while the fuse (106) remains electrically connected to the lower fuse terminal (156) and to the load side terminal (162). An arc blowing box compartment (184) can be formed in the housing (104) below the switchable contacts (172) and (174), and the arc blowing box can provide a space to contain and dissipate the energy of arc as the switchable contacts (172) and (174) are disconnected. The arc formation is broken at two sites in each of the contacts (172) and (174), thus reducing the arc intensity, and the arc formation is contained within the lower portions of the housing (104) and away from the upper surface (118) and the hands of a user when manipulating the switch actuator (110) to disconnect the fuse (106) from the terminal on the line side (142). The housing (104) can additionally including a securing ring (186) that can be cooperatively used with a retention opening (188) in the body of the switch actuator (166) to secure the switch actuator (110) in one of the closed position shown in the Figure 2 and the open position shown in Figure 3. A securing pin for example, can be inserted through the securing ring (186) and the retaining opening (188) to restrict the switch actuator in the open or closed position. correspondent. Additionally, a fuse retention arm could be provided on the switch actuator (110) to prevent removal of the fuses, except when the switch actuator (110) is in the open position. Figure 3 illustrates the circuit breaker module (102) after the switch actuator has been moved in the direction of the arrow A to an open or commutated position to disconnect the switchable contacts (172) and (174) from the stationary contacts (178) and (180). As the actuator moves toward the open position, the actuator body (166) rotates around the shaft (134) and the actuator link (168) therefore moves upwardly in the actuator compartment (164). According to the link (168) moves upwards, the link (168) pulls the slide bar (176) upwards in the direction of the arrow B to separate the switchable contacts (172) and (174) from the stationary contacts (178) and ( 180). A bypass element (200) can be provided below the slide bar (176) and can force the slide bar (176) up in the direction of the arrow B to a fully open position, separating the contacts (172), (174) and (178), (180) from each other. In this way, as the actuator body (166) is rotated in the direction of the arrow A, the link (168) moves past a point of equilibrium and the bypass element (200) helps to open the contacts (172) , (174) and (178), (180). The bypass element (200) therefore prevents partial opening of the contacts (172), (174) and (178) (180) and ensures a total separation of the contacts to safely interrupt the circuit through the module (102). Additionally, when the actuator lever (136) is pulled back in the direction of the arrow C to the closed position shown in Figure 2, the linkage of the actuator (168) moves to the position of the slide bar (176) downward in the direction of the arrow D to connect and close the contacts (172), (174) and (178), (180) and reconnect the circuit by means of the fuse (106). The slide bar (176) moves down against the bypass of the bypass element (200), and once it is in the closed position, the slide bar (176), the link of the actuator (168) and the switch actuator. they are in static equilibrium, so that the switch actuator (110) will remain in the closed position. • In an exemplary embodiment, and as illustrated in Figures 2 and 3, the bypass element (200) may be a helical spring element that is engaged in compression in the closed position of the switch actuator (110). It will be appreciated, however, that in an alternative embodiment, a coil spring could be charged in tension when the switch actuator (110) is closed. Additionally, other known bypass elements could be provided to produce opening and / or closing forces to assist in the proper operation of the circuit breaker module (102). 'The bypass elements can also be used for damping purposes when the contacts are open. The lever (136), when moving between the open and closed positions of the switch actuator, does not interfere with the work space around the circuit breaker module (102), and the lever (136) is likely to be involuntarily returned to the closed position from the open position. In the closed position shown in Figure 3, the lever (136) is located adjacent one end of the fuse (106). Therefore, the fuse (106) partially protects the lever (136) from the involuntary contact and the unintentional actuation to the closed position. The bypass element (200) further provides some resistance to the movement of the lever (136) and to the closure of the contact mechanism. Additionally, the stationary contacts (178) and (180) are always protected by the housing (104) of the module (102), and any risk of electric shock due to contact with the terminal on the side of the line (142) and the stationary contacts (178) and (180), is avoided. The circuit breaker module (102) is therefore considered to be safer than many known fuse disconnection devices. When the modules (102) are serially configured to form a multi-pole device, such as the device (100), a lever (136) can extend through and connect to multiple switch actuators (110) for different modules. So, all connected modules (102) can be disconnected and reconnected by manipulating a single lever (136). That is, the multiple poles in the device (100) can be switched simultaneously. Alternatively, the actuators of the switch (110) of each module (102) in the device (100) can be operated independently with separate levers (136) for each module. Figure 4 is a side elevational view of a further exemplary embodiment of a fuse breaker (102) including, for example, a retractable locking flat plug (210) that can be extended from the switch actuator (110) when the lever (136) moves towards the open position. The flat locking plug (210) may be provided with a securing opening (212) therethrough, and a padlock or other element may be inserted through the securing opening (212) to ensure that the lever (136). ) can not be moved to the closed position. In different embodiments, the flat lock plug 210 can be spring loaded and extended automatically, or it can be manually extended from the switch actuator body 166. When the lever (136) moves to the closed position, the flat locking plug (210) can be returned automatically or manually to the retracted position, wherein the switch actuator (110) can be rotated back to the closed position shown in Figure 2. Figure 5 is a perspective view of a third exemplary embodiment of a fuse circuit breaker module (FIG. 220) similar to the module (102) described above but having, for example, a DIN rail mounting groove (222) formed in a lower edge (224) of a housing (226). The housing (226) may also include openings (228) that can be used to serially configure the module (220) to other disconnect modules. The lateral edges (230) of the housing (226) may include connection openings (232) for line-side and load connections to the box lugs or to the brackets within the housing (226). The access openings (234) may be provided on recessed upper surfaces (236) of the housing (226). An unlined cable, for example, may extend through the connection openings (232) and a screwdriver may be inserted through the access openings (234) to connect the line and load circuitry to the module (220). ). As the module (102), the module (220) can include the fuse (106), the fuse cover (108) and the switch actuator (110). The switching of the module is achieved with switchable contacts as described above in relation to the module (102). Figures 6 and 7 are perspective views of a fourth exemplary embodiment of a fuse circuit breaker module (250) which, like the modules (102) and (220) described above, includes a switch actuator (110) rotatably mounted to the housing on a shaft (134), a lever (136) extending from the link of the actuator (168) and a slide bar (176). The module (250) also includes, for example, a mounting clip (144) and a terminal element on the line side (142). Different from the modules (102) and (220), the module (250) may include a housing (252) configured or adapted to receive a rectangular fuse module (254) instead of a cartridge fuse (106). The fuse module (254) is a known assembly that includes a rectangular housing (256), and terminal blades (258) that extend from the housing (256). A fuse or fuse assembly element may be located within the housing (256) and electrically connected between the terminal blades (258). Such fuse modules (254) are known and in one embodiment are CubeFuse modules commercially available from Cooper / Bussmann of St. Louis, Missouri. A line-side fuse clip (260) may be located within the housing (252) and may receive one of the terminal blades (258) of the fuse module (254). A fuse clip on the load side (262) may also be located within the housing (252) and may receive the other fuse terminal blades (258). The fuse clamp on the line side (260) may be electrically connected to the stationary contact (180). The fuse clip on the load side (262) may be electrically connected to the load side terminal (162). The terminal on the line side (142) may include the stationary contact (178), and switching may be achieved by turning the switch actuator (110) to engage and decouple the switchable contacts (172) and (174) with the respective stationary contacts (178) and (180) as described above. Since the line terminal (142) is illustrated as a bus bar clamp, it is clear that other line terminals can be used in other modes, and the load side terminal (162) can also be another type of terminal in place of the support screw terminal illustrated in another embodiment. The fuse module (254) can be plugged into or removed from the fuse clips (260), (262) to install or remove the fuse module (254) from the housing (252). For switching purposes, however, the circuit is switched on and off at the contacts (172), (174) and (178) and (180) instead of the fuse clamps (260) and (262). The arc formation between the disconnected contacts therefore I can be contained in a blow box of the arc or compartment (270) in the lower portion of the compartment and away from the fuse clamps (260) and (262). By opening the circuit breaker module (250) with the switch actuator (110) before installing or removing the fuse module (254), any risk faced by the arcing of arc or energized metal in the fuse and in the interface is eliminated. of the accommodation. It is believed that the circuit breaker module (250) is therefore safer to use than many known fuse circuit breakers. A plurality of modules (250) may be configured in series or otherwise connected together to form a multi-pole device. The poles of the device could be operated with just one lever (136) or independently operable with different levers. Figure 8 is a perspective view of a fifth exemplary embodiment of a fuse breaker device (300) which is, for example, a multi-pole device in an integrated housing (302). The housing (302) can be constructed to accommodate three fuses (106) in an exemplary embodiment, and is therefore well suited for a three-phase power application. The housing (204) may include a DIN rail slot (304) in the illustrated embodiment, although it is clear that other mounting options, mechanisms, and mounting schemes may be used in alternative embodiments. Additionally, in one embodiment, the housing (204) may have a width dimension D of about 45 mm in accordance with the IEC industrial standards for contactors, relays, manual motor protectors, and integral starters that are also commonly used in utility applications. industrial control systems. The benefits of the invention, however, also accrue to devices having different dimensions and devices for different applications. The accommodation may also include openings connection (306) and access openings (308) on each side edge (310) that can receive a wired connection and a tool, respectively, to establish line and load connections to the fuses (106). A simple switch actuator (110) can be rotated to connect and disconnect the circuit through the fuses between the line and load terminals of the circuit breaker device (300). Figure 9 is a perspective view of an exemplary switching assembly (320) for the device (300). The switching assembly may be accommodated in the housing (302) and in an exemplary embodiment may include a group of line terminals (322), a group of load terminals (324), a group of lower fuse terminals (326) associated with each respective fuse (106), and a group of slide bars (176) having switchable contacts mounted thereon for coupling and uncoupling stationary contacts mounted to the ends of line terminals (322) and lower fuse terminals (324). An actuator link (not visible in Figure 9) may be mounted to a drive shaft (134), such that when the lever (136) is rotated, the slide bar (176) may be moved to disconnect the contacts switchable contacts of stationary contacts. The bypass elements (200) can be provided below each of the slide bars (176) and assist in the operation of the switch actuator (110) as described above. As with the above embodiments of modules, a range of terminal structures on the line side and on the load side can be used in various modes of the switching assembly. The holding bars (328) can also be provided on the shaft (134) which extends to the fuses (106) and which couples the fuses in an interlock manner to prevent the fuses (106) from being removed from the device (300). ), except when the switch actuator (110) is in the open position. In the open position, the retainer bars 328 can be angled away from the fuses 106 and the fuses can be freely removed. In the closed position, as shown in Figure 9, the retaining arms or bars (328) secure the fuse in place. In an exemplary embodiment, the distal ends of the bars or arms (328) may be received in slots or detents in the fuses (106), although the fuses (106) could be secured in another manner as desired.

Figure 10 is a perspective view of a sixth exemplary embodiment of a fuse breaker device (370) including the breaker module (300) described above and, for example, a subvoltage module (372) mounted on one side of the module (300) and mechanically linked to the switching mechanism in the module (300). In an exemplary mode, the undervoltage module (372) may include an electromagnetic coil (374) calibrated at a predetermined voltage range. When the voltage falls below the range, the electromagnetic coil causes the switch contacts in the module (300) to open. A similar module (372) could be employed in an alternative embodiment to open the switch contacts when the voltage experienced by the electromagnetic exceeds a predetermined voltage range, and can therefore serve as an overvoltage module. In this way, the switching contact in the module (300) could be opened with the module (372) and the coil (374) as undervoltage or overvoltage conditions occur. Figure 11 is a perspective view of a seventh exemplary embodiment of a fuse breaker device (400) which is essentially the breaker device (300) and a breaker device (220) coupled together. The circuit breaker device (300) provides three poles for an alternating current (AC) power circuit and the device (220) provides an additional pole for other purposes. Figure 12 is a perspective view of an eighth embodiment of a fuse circuit breaker module (410) which, as in the above embodiments, includes a non-conductive housing (412), a switch actuator (414) extending through of a raised upper surface (415) of the housing (412), and a cover (416) that provides access to a fuse socket (not shown in Figure 12) within the housing (412) for installation and relocation of a fuse for overcurrent protection (also not shown in Figure 12). As in the above embodiments, the housing (412) includes switchable and stationary contacts (not shown in Figure 12) that complete or interrupt an electrical connection by means of the fuse in the housing (412) via the movement of an actuating lever (417). ). A DIN rail mounting groove (418) can be formed in a lower edge (420) of the housing (412), and the DIN rail mounting slot (418) can have dimensions, for example, for quick coupling and uncoupling with a 35 mm DIN rail manually and without the need for tools. The housing (412) may also include openings (422) which can be used to serially configure the module (410) or other disconnection modules as explained below. The side edges (424) of the housing (412) can be open ended to provide access to the wired lug terminals (426) to establish line-side and load-side electrical connections, external to the circuitry. Terminal access openings (428) can be provided on recessed top surfaces (430) of the accommodation (412). An unlined cable, for example, may extend across the sides of the wired lug terminals 426 and a screwdriver may be inserted through the access openings 428 to tighten a terminal screw to hold the wires. to the terminals (426) and connect line and load circuitry to the module (410). While the wired lug terminals 426 are included in one embodiment, it is clear that a range of alternative terminal configurations or types can be used in other embodiments to establish line side and wiring side electrical connections. charging the module (410) by means of wires, cables, busbars, etc. As in the above embodiments, the housing (412) is sized and is of complementary dimensions to and compatible with DIN and IEC standards, and the housing (412) defines an area or footprint on the lower edge (420) for use with openings standardized that have a complementary shape and dimension. By way of example only, the housing (412) of the single-pole module (410) can have a thickness T of approximately 17.5 mm for a disconnection capacity of up to 32 A; 26 mm for a disconnection capacity of up to 50 A, 34 mm for a disconnection capacity of up to 125 A; and 40 mm for a disconnection capacity of up to 150 A by the standard DIN 43 880. Likewise, it is understood that the module (410) could be manufactured as a multi-pole device such as a three-pole device having a T dimension of approximately 45 mm for a disconnection capacity of up to 32 A; 55 mm for a disconnection capacity of up to 50 A, and 74 ram for a disconnection capacity of up to 125 A. While exemplary dimensions are provided, it is understood that other dimensions of higher values may also be used. minors in alternative embodiments of the invention. Additionally, and as illustrated in Figure 12, the side edges (424) of the housing (412) may include opposite pairs of vertically oriented tabs (432) spaced apart from each other and projecting away from the wired lug terminals (426). adjacent to the upper surface of the housing (430) and to the sides of the wired lug terminals (426). The eyelashes (432), sometimes referred to as wings, provide an increased surface area of the housing (412) in a horizontal plane extending between the wired lug terminals (426) at the opposite lateral edges. (424) of the housing (412) that could otherwise occur if the tabs (432) were not present.

That is, a peripheral outer surface area path length extends in a plane parallel to the lower surface (420) of the housing (412), includes the sum of the outer surface dimensions of one of the pairs of tabs (432) extending from one of the terminals (426), the outer dimensions of the respective front or rear panel (431), ( 433) of the housing, and the outer surface dimensions of the opposing flanges (432) extending to the terminal opposite (426). Additionally, the housing (412) may also include projections or shelves (434) that extend horizontally, spaced apart from one another and interconnecting the innermost flanges (432) in a lower portion of the side edges of the housing (424). The projections or ledges (434) increase a surface area path length between the terminals (426) in a vertical plane of the housing (412) to meet the external space requirements between the terminals (426). The flanges (432) and the projections (434) result in surface areas in serpentine form in the horizontal and vertical planes of the housing (412) that allow higher voltage regimes of the device, without increasing the footprint of the module (410) in comparison , for example, with the previously described embodiments of Figures 1-11. For example, the tabs (432) and the projections (434), facilitate a voltage regime of 600 volts of alternating current (VAC, by its abbreviation in English), while meeting the internal and external space requirements applicable between the terminals (426) under applicable UL standards. The cover (416), other than the embodiments described above, may include a portion of substantially flat cover (436), and a vertical finger holding portion (438) projecting up and out from one end of the flat cover portion (436) and facing the switch actuator (414) . The cover may be made of a non-conductive material or insulating material such as plastic, according to known techniques, and the flat cover portion (436) may be hinged at one end thereof, opposite the finger holding portion ( 438) in such a way that the cover portion (436) pivots about the hinge. Thanks to the hinge, the finger clamping portion (438) is movable outside the switch actuator, together with an arcuate path as explained in more detail below. As illustrated in Figure 12, the cover (416) is in a closed position that hides the fuse within the housing (412), and as explained below, the cover (416) is movable for an open position providing access to the fuse in the circuit breaker module (410). Figure 13 is a side elevational view of the module (410) with the front panel (431) (Figure 12) removed, so that the internal components and features can be observed. The wired lug terminals (426) and the terminal screws (440) are positioned adjacent the side edges (424) of the housing (412). A fuse (442) is loaded or inserted into the module (410) in a direction substantially perpendicular to the upper surface of the housing (415), and as illustrated in Figure 13, a longitudinal axis (441) of the fuse (442) it extends vertically, as opposed to horizontally, within the housing (412). The fuse (442) is contained within the housing (412) below the cover (416), and more specifically below the flat cover portion (436). The fuse (442) is located longitudinally in a fuse socket (437) formed integrally in the housing (412). That is, the fuse socket (437) is not mobile in relation to the housing (502) for loading and unloading the fuse (442). The fuse (442) is received in the receptacle (437) with one end of the fuse (442) placed adjacent and below the cover (416) and the upper surface of the module (415) and the other end of the fuse (442) spaced of the cover (416) and the upper surface of the module (415) by a distance equal to the length of the fuse (442). An interlock of the actuator (443) is formed with the cover (416) and extends down into the adjacent housing (412) and next to the fuse socket (437). He interlock of the actuator (443) of the cover (416) extends opposite and away from the cover finger fastening portion (438). A flat cover locking plug (444) extends radially outwardly from a cylindrical body (446) of the switch actuator (414), and when the switch actuator (414) is in the closed position illustrated in Figure 13, complete an electrical connection by means of the fuse (442), the flat cover locking plug (444) extends generally perpendicular to the interlock of the actuator (443) of the cover (416) and a distal end of the flat cover locking plug (444) is positioned adjacent the interlock of the actuator (443) of the cover (416). The flat cover locking plug (444) therefore directly opposes the movement of the interlock of the actuator (443) and resists any attempt by a user to pivot the cover (416) around the cover hinge (448) in the direction of the arrow E to open the cover (416). Thus, the fuse (442) can not be accessed without first turning the switch actuator (414) in the direction of the arrow F to move the pair of switchable contacts (450) away from the stationary contacts (452) via the actuator link (454) and the slide bar (456) carrying the switchable contacts (450) in a manner similar to the previous modes. Involuntary contact with energized portions of the fuse (442) is therefore prevented, since the cover (416) can only be opened to access the fuse (442) after the circuit through the fuse (442) is disconnected via the switchable contacts (450), thereby providing a degree of security to the human operators of the module (410). Additionally, and because the cover (416) hides the fuse (442) when the switchable contacts (450) are closed, the outer surfaces of the housing (412) and the cover (416) are secure when touched. A conductive path through the housing (412) and the fuse (442) is established as follows. A rigid end member (458) extends from the load side terminal (426) closest to the fuse (442) on one side of the housing (412). A flexible contact member (460), such as a cable may be connected to the terminal member (458) at one end and attached to an inner surface of the cover (416) at the opposite end. When the cover (416) is closed, the contact member (460) is put into mechanical and electrical coupling with a bushing top or end cap (462) of the fuse (442). A terminal of the movable lower fuse (464) is mechanically and electrically connected to the end cap or cap of the lower fuse (466), and a flexible contact member (468) interconnects the terminal of the moving lower fuse (464) to a stationary terminal (470) bearing one of the stationary contacts (452). The switchable contacts (450) interconnect the stationary contacts (452) when the switch actuator (414) is closed, as shown in Figure 13. A rigid terminal member (472) completes the circuit path to the terminal on the power side. the line (426) on the opposite side of the housing (412). During use, current flows through the path of the circuit from the terminal on the line side (426) and the terminal member (472), through the switch contacts (450) and (452) towards the member terminal (470). From the terminal member (470), the current flows through the contact member (468) towards the lower fuse terminal (464) and through the fuse (442). After flowing through the fuse (442), the current flows to the contact member (460) towards the terminal member (458) and to the terminal on the line side (426). The fuse (442) in different modes copies may be a 10x38 Midget fuse commercially available from Cooper / Bussmann of St. Louis, Missouri; a 10x38 IEC fuse; a class CC fuse; or a European style D / DO fuse. Additionally, and as desired, optional fuse reject features can be formed in the lower fuse terminal (464) or anywhere in the module, and cooperate with the fuse rejection characteristics of the fuses, so that only certain types of fuses can be properly installed in the module (410). Since certain examples of fuses are described herein, it is understood that other types and configurations of fuses may also be employed in alternative embodiments, including without restriction various types of cylindrical or cartridge fuses and rectangular fuse modules. A bypass element (474) may be provided between the terminal of the mobile lower fuse (464) and the stationary terminal (470). The bypass element (474) can be, for example, a helical spiral spring that is compressed to provide an upward bypass force in the direction of the arrow G to ensure the mechanical and electrical coupling of the mobile lower fuse terminal ( 464) to the lower fuse bushing (466) and mechanical and electrical coupling between the upper fuse bushing (462) and the flexible contact member (460). When the cover (416) opens in the direction of the arrow E towards the open position, the bypass element (474) forces the fuse upwards, along its axis (441) in the direction of the arrow G as is shown in Figure 14, exposing the fuse (442) through the raised upper surface (415) of the housing (412) for easy retrieval by an operator for replacement. That is, the fuse (442), thanks to the bypass element (474), automatically rises and is ejected from the housing (412) when the cover (416) rotates around the hinge (448) in the direction of the arrow E after the switch actuator (414) is rotated in the direction of the arrow F. Figure 15 is a side elevational view of the module (410) with the cover (416) pivoted about the hinge (448) and the switch actuator (414) in the open position. The switchable contacts (450) are moved up by rotation of the actuator (414) and the displacement of the link of the actuator (454) causes the slide bar (456) to move along a linear axis (475) substantially parallel to the shaft (441) of the fuse (442), separating physically the switchable contacts (450) of the stationary contacts (452) within the housing (412) and disconnecting the conductive path through the fuse (442). Additionally, and because of the pair of switchable contacts (450), the electric arc formation is distributed among more than one site as described above. The bypass element (474) is deflected when the cover (416) opens after the actuator (414) moves to the open position, and the bypass member (474) raises the fuse (442) of the housing (412) ), so that the upper fuse bushing (462) extends above the upper surface (415) of the housing. In such a position, the fuse (442) can be easily grasped and removed or removed from the module (410) along the axis (441). Therefore, the fuses can be easily removed from the module (410) for replacement. Also, when the actuator (414) is moved to the open position, a flat plug for locking the actuator (476) extends radially outwardly from the actuator body of the switch (446) and can accept for example, a padlock to prevent the involuntary closing of the actuator (414) in the direction of the arrow H that could otherwise cause the Slide bar (456) moves downward in the direction of arrow I along shaft (475) and engage switchable contacts (450) to stationary contacts (452), again completing electrical connection to fuse (442) and presenting a risk prevention for operators. When desired, the cover (416) can be rotated rearwardly around the hinge (448) to the closed position shown in Figures 12 and 13, and the switch actuator (414) can be rotated in the direction of the arrow H to move the flat cover interlock plug (444) in engagement with the interlock of the actuator (443) of the cover (416) to hold each of the cover (416) and the actuator (414) in static equilibrium in a closed and secured position. The closing of the cover (416) requires some force to overcome the resistance of the bypass spring (474) in the fuse socket (437), and the movement of the actuator to the closed position requires some force to overcome the resistance of an element. of derivation (478) associated with the slide bar (456), resulting in the involuntary closing of the contacts and termination of the circuit through the module (410) much less likely. Figure 16 is a perspective view of a serial configuration of fuse circuit breaker modules (410). The connectors (480) can be made of plastic, for example, and can be used with the openings (422) in the housing panels for retaining the modules (410) in a side-to-side relationship for example, with the quick-release coupling. The pins (482) and / or wedges (484), for example, can be used to join or link the actuator levers (417) and the portions to hold the cover fingers (438) of each module (410) to another, in such a way that all the actuating levers (417) and / or all the covers (416) of the combined modules (410) move simultaneously with each other. The simultaneous movement of the covers (416) and levers (417) can be especially advantageous for cutting the three-phase current or, as another example, when the switching power to the related equipment, such as motor and a cooling fan for the motor, so that one does not operate without the other. While single-pole modules 410 have been described which are configured in series with each other to form multi-pole devices, it is understood that a multi-pole device having the characteristics of the module 410 could be constructed in a single housing, with appropriate modification of the mode shown in Figures 8 and 9, for example. Figure 17 is a perspective view of a ninth embodiment of a fuse breaker module (500) which, as in the above embodiments, includes a single pole housing (502), a switch actuator (504) extending through a raised upper surface (506) of the housing (502), and a cover (508) that provides access to a fuse socket (not shown in Figure 17) within the housing (502) for installation and replacement of an overcurrent protection fuse (Also not shown in Figure 17). As in the above embodiments, the housing (502) includes switchable and stationary contacts (not shown in Figure 17) that connect or disconnect an electrical connection by means of the fuse in the housing (502) via the movement of an actuator lever (510). ). Similar to the module (410), the module (500) may include a DIN rail mounting slot (512) formed in a lower edge (514) of the housing (502) for mounting the housing (502) without the need for tools . The housing (502) may also include an opening of the actuator (515) that provides access to the actuator body of the switch (504), so that the actuator (504) may rotate between the open and closed positions in an automatic way and facilitate remote control of the module (500). The openings (516) are also provided so that they can be used to serially configure the module (500) to other disconnect modules. An arcuate or curved interruption guide groove (517) is also formed in a front panel of the housing (502). A sliding interrupting mechanism, described below, can be selectively placed within the slot (517) to interrupt the module (500) and disconnect the current path by means of this after the appearance of predetermined circuit conditions. The slot (517) also provides access to the interruption mechanism for manual interruption of the mechanism with a tool, or to facilitate remote interruption capability. The side edges (518) of the housing (502) may be open ended to provide access to the wired lug terminals on the line side and the load (520) to establish the electrical connections on the load side and the load side. line to the module (500), although it is understood that other types of terminals can be used. The terminal access openings (522) may be provided on recessed upper surfaces (524) of the housing (502) for receiving an unlined cable or other conductor extended across the sides of the wired lug terminals (520), and a screwdriver can be inserted through the access openings (522) to connect the line circuitry and loading the module (500). As in the above embodiments, the housing (502) is sized and is of complementary dimensions to and compatible with the DIN and IEC standards, and the housing (502) defines an area or footprint on the lower surface (514) of the housing for used with standardized openings that have a complementary shape and dimension. Like the module (410) described above, the side edges (518) of the housing (502) can include opposite pairs of vertically oriented flanges or tabs (526), spaced apart from and protruding from the adjacent wired lug terminals (520) to the upper housing surface (524) and to the sides of the wired lug terminals (520). The housing (502) may also include projections or shelves (528) that extend horizontally, spaced apart from one another and interconnecting the innermost flanges (526) in a lower portion of the side edges of the housing (518). The tabs (526) and the projections (528) result in surface areas in serpentine form, in horizontal and vertical planes of the housing (502) that allow higher voltage regimes of the device without increasing the footprint of the module (500) as explained above. The cover (508), other than the embodiments described above, may include a contoured outer surface that defines a peak (530) and a concave section (532) that slopes downwardly from the peak (530) and faces the actuator of the switch (504). The peak (530) and the concave section (532) form a finger protection area on the surface of the cover (508) and are suitable for example, to serve as a thumb rest for an operator that will open or close the cover (508). The cover (508) may be hinged at one end thereof, closer to the peak (530) so that the cover (508) pivots about the hinge and the cover (508) is movable away from the switch actuator (504). ) along an arched path. As illustrated in Figure 17, the cover (508) is in a position that is secure when touched, closed, that the fuse hides within the housing (502), and as explained below, the cover (508) is mobile to an open position by providing access to the fuse. Figure 18 is a side elevation view of a portion of the fuse breaker module (500) with a front panel thereof removed, so that internal components and features can be observed. In some aspects, the module (500) is similar to the module (410) described above in its internal components, and for brevity the similar characteristics of the modules (500) and (410) are indicated with similar reference numbers in Figure 18 The wired lug terminals (520) and the terminal screws (440) are positioned adjacent the side edges (518) of the housing (502). The fuse (442) is loaded vertically within the housing (502), below the cover (508), and the fuse (442) is located in the outlet of the motionless fuse (437) formed in the housing (502). The cover (508) may be formed with a conductive contact member which may be, for example, cup-shaped to receive the upper fuse bushing (462) when the cover (408) is closed. A conductor circuit path is established from the terminal on the line side (520) and the terminal member (472), by means of the switch contacts (450) and (452) to the member terminal (470). From the terminal member (470), current flows through the contact member (468) to the lower fuse terminal (464) and through the fuse (442). After flowing through the fuse (442), current flows from the conductive contact member (542) of the cover (508) to the contact member (460) connected to the conductive contact member (542), and from the contact member (460) to the terminal member (458) and to the terminal on the line side (426). A bypass element (474) can be provided between the terminal of the movable lower fuse (464) and the stationary terminal (470), as described above to ensure the mechanical and electrical connection between the cover contact member (542) and the upper fuse bushing (462) and between the lower fuse terminal (464) and the lower fuse bushing (466). Also, the bypass element (474) automatically ejects the fuse (442) from the housing (502) as described above, when the cover (508) is rotated around the hinge (448) in the direction of the arrow E, then that the actuator of the switch (504) is rotated in the direction of the arrow F. Different to the module (410), the module (500) it may further include an interruption mechanism (544) in the form of a slidable-mounted interruption bar (545) and a solenoid (546) connected in parallel through the fuse (442). The interruption bar (545) is slidably mounted to the interruption guide groove (517) formed in the housing (502), and in an exemplary embodiment, the interruption bar (545) may include a solenoid arm (547), a cover interlock arm (548) extending substantially perpendicular to the solenoid arm (547); and a support arm (550) extending obliquely to each of the solenoid arm (547) and to the interlock arm of the solenoid arm (547). cover (548) The support arm (550) may include a latching lug (552) at a distal end thereof. The body (446) of the switch actuator (518) can be formed with a flange (554) cooperating with the latching lug (552) to maintain the interruption bar (545) and the actuator (504) in static equilibrium with the solenoid arm (547) that is supports on a top surface of the solenoid (546). A torsion spring (555) is connected to the housing (502) at one end and to the body of the actuator (446) at the other end, and the torsion spring (555) deflects the switch actuator (504) in the direction of arrow F to the open position. That is, the torsion spring (555) is resistant to the movement of the actuator (504) in the direction of the arrow H and tends to force the actuator body (446) to rotate in the direction of the arrow F to the open position . In this way, the actuator (504) is fail-safe thanks to the torsion spring (555). If the switch actuator (504) is not completely closed, the torsion spring (555) will force it to the open position and prevent the involuntary closing of the switch-able contacts by the actuator (450), together with the safety and reliability issues. associated with the incomplete closure of the switchable contacts (450) related to the stationary contacts (452). Under normal operating conditions, when the actuator (504) is in the closed position, the tendency of the torsion spring (555) to move the actuator to the open position is counteracted by the support arm (550) of the interruption bar (545), as shown in Figure 18. The latch lug (552) of the solenoid arm (550) engages the flange (554) of the actuator body (446) and holds the actuator (504) stably in static equilibrium in a closed and secured position. Once the The latching lug (552) is released from the rim (554) of the actuator body (446), however, the torsion spring (555) forces the actuator (504) to the open position. An interlock of the actuator (556) is formed with the cover (508) and extends down into the housing (502), adjacent to the fuse socket (437). The cover interlock arm (548) of the interruption arm (545) is received in the interlock of the actuator (556) of the cover (508) and prevents the cover (508) from being opened, except that the switch actuator ( 504) is turned in the direction of arrow F as explained below, to move the interruption bar (545) and release the cover interlock arm (548) from the interrupter bar (545) of the actuator interlock (556). ) of the cover (508). The deliberate rotation of the actuator (504) in the direction of the arrow F causes the latch lug (552) of the solenoid arm (550) of the interrupter bar (545) to pivot away from the actuator and causes the solenoid arm (547) it becomes inclined or angular with respect to the solenoid (546). The inclination of the interruption bar (545) results in an unstable position and the torsion spring (555) forces the actuator (504) to rotate and then pivot the interruption bar (545) to the release point. Without deliberate movement of the actuator to the open position in the direction of arrow F, the interruption bar (545), via the interlock arm (548), directly opposes the movement of the cover (508) and resists any attempt of a user to rotate the cover (508) around the cover hinge (448) in the direction of the arrow E to open the cover (508), while the switch actuator (504) is closed and the switch contacts (450) they are coupled to the stationary contacts (452) to complete a circuit path by means of the fuse (442). The involuntary contact with energized portions of the fuse (442) is therefore prevented, since the fuse can only be accessed when the circuit through the fuse is cut off via the switchable contacts (450), thereby providing a degree of safety to the human operators of the module (500). Upper and lower solenoid contact members (557), (558) are provided and establish electrical contact with the respective upper and lower bushes (462), (466) of the fuse (442) when the cover (508) is closed on the fuse (442). The contact members (557), (558) establish, in turn, electrical contact to a circuit board (560). The resistors (562) are connected to the circuit board (560) and define a high resistance parallel circuit path through the bushes (462), (466) of the fuse (442), and the solenoid (546) is connected to this parallel circuit path in the circuit board (560). In an exemplary embodiment, the resistor is selected such that, in normal operation, virtually all of the current flow passes through the fuse (442) between the fuse holders (462), (466) instead of through the the upper and lower solenoid contact members (557), (558) and the circuit board (560). The solenoid coil (546) is calibrated, so that when the solenoid (546) experiences a predetermined voltage, the solenoid generates an upward force in the direction of the arrow G which causes the interruption bar (545) to be displaced in the interruption guide slot (517) along an arcuate path, defined by the slot (517). As those skilled in the art can appreciate, the solenoid coil (546) may be calibrated to respond to an undervoltage condition default or to a predetermined overvoltage condition, as desired. Additionally, the circuit board (560) may include circuitry to actively control the operation of the solenoid (546), in response to the conditions of the circuit. In addition, the contacts may be provided on the circuit board (560) to facilitate the remote control interruption of the solenoid (546). Thus, in response to the abnormal circuit conditions that are predetermined by the calibration of the solenoid coil or the control circuitry in the board (560), the solenoid (546) is activated to move the interruption bar (545). Depending on the configuration of the solenoid (546) and / or the board (560), the opening of the fuse (442) may or may not activate an abnormal condition of the circuit, causing the solenoid (546) to activate and move the interruption bar (545). As the interruption bar (545) traverses the arcuate path in the guide slot (517) when the solenoid (546) operates, the solenoid arm (547) pivots and becomes inclined or angled with respect to the solenoid (546). The inclination of the solenoid arm (547) causes the interruption bar (545) to become unstable and be susceptible to forcing the torsion spring (555) to act on the engagement lug of the interrupting arm (552) via the rim (554) in the actuator body (446). As the torsion spring (555) begins to rotate the actuator (504), the interruption bar (545) further pivots, due to engagement of the latch lug of the interrupting arm (552) and the flange of the actuator (554) and becomes even more unstable and is subjected to the force of the torsion spring. The interruption bar (545) is further moved and pivoted by the combined action of the guide groove (517) and the actuator (504), until the latch lug of the interrupting arm (552) is released from the flange of the actuator ( 554), and the interlock arm (548) of the interruption bar (545) is released from the interlock of the actuator (556). At this point, each of the actuator (504) and the cover (518) rotate freely. Figure 19 is a side elevational view of the fuse breaker module (500) illustrating the solenoid (546) in an interrupting position, wherein a solenoid piston (570) is moved up and engages the interrupter bar ( 545), causing the interruption bar (545) to move along the curved guide groove (517) and to reach tilt and become unstable with respect to the piston.

As the interruption bar (545) moves and pivots to become unstable, the torsion spring (555) helps to cause the interruption bar (545) to become more unstable as described above, until the flange (554) of the actuator body (446) is released from the latching lug. (552) of the interruption bar (545), and the torsion spring (555) forces the actuator (504) to rotate fully to the open position shown in Figure 19. As the actuator (504) rotates to the open position , the link of the actuator (454) pulls the slide bar (456) upwards, along the linear axis (475) and separates the switchable contacts (450) from the stationary contacts (452) to open or disconnect the circuit path between the terminals of the housing (520). Additionally, the pivoting movement of the interruption bar (545) releases the interlock of the actuator (556) of the cover (508), allowing the bypass element (474) to force the fuse upwardly from the housing (502) and cause the cover (508) to pivot about the hinge (448), so that the fuse (442) is exposed for easy removal and replacement.

Figure 20 is a perspective view of the fuse breaker module (500) in the interrupted position and the relative positions of the actuator (504), the interruption bar (545) and the cover (508). As also shown in Figure 20, the slide bar (456) carrying the switchable contacts (450) can be aided in the open position by a first branch element (572), external to the slide bar (456) and a second branch element (574) internal to the slide bar (456). The bypass elements (572), (574) may be axially aligned with each other, but oppositely charged in one embodiment. The bypass elements (572), (574) can be, for example, helical spiral spring elements, and the first bypass element (572) can be loaded in compression, for example, while the second bypass element (574). ) is charged in tension. Therefore, the first branch member (572) exerts an upward thrust force (572) on the slide bar (456), while the second branch member (574) exerts a pull force directed upwardly in the slide bar (456). The combined forces of the bypass elements (572), (574) force the slide bar in one direction upwards, indicated by the arrow G when the actuator is turned to the open position as shown in Figure 20. The double spring action of the bypass elements (572), (574), together with the torsion spring ( 555) (Figures 18 and 19) acting on the actuator (504), ensures rapid, automatic and complete separation of the switchable contacts (450) from the fixed contacts (452) in a reliable manner. Additionally, the double spring action of the bypass elements (572), (574) effectively prevents and / or compensates for the contact jump when the module (500) is operating. Also as illustrated in Figure 20, the interlock of the actuator (556) of the cover (508) is substantially U-shaped in an exemplary embodiment. As seen in Figure 21, the interlock (556) extends downwardly into the housing (502), when the cover (508) is in the closed position on the fuse (442), loading the bypass element (474). in compression. Figure 22 illustrates the cover interlock arm (548) of the interruption bar (545) aligned with the interlock of the actuator (556) of the cover (508), when the cover (508) is in the closed position. In such a position, the actuator (504) can be rotated backward in the direction of the arrow H to move the slide bar (456) downward in the direction of the arrow I to engage the switchable contacts (450) to the stationary contacts (452) of the housing (502). As the actuator (504) is rotated in the direction of the arrow H, the interruption bar (545) is pivoted back to the position shown in Figure 18, stably holding the actuator (504) in the closed position, in a interlocking configuration with the cover (508). The interruption bar (545) can be spring loaded to further assist the interrupting action of the module (500) and / or the return of the interruption bar (545) to the stable position, or even more so to deflect the arm of interruption (544) to a predetermined position with respect to the interruption guide slot (517). Figures 23 and 24 illustrate a tenth embodiment of a fuse breaker device (600) including a breaker module (500) and an auxiliary contact module (602) coupled or serially configured to the housing (502) in a side relation next to the module (500) via the openings (516) (Figure 17) in the module (500). The auxiliary contact module (602) may include a housing (604) generally complementary in shape to the housing (502) of the module (500), and may include an actuator (604) similar to the actuator (508) of the module (500). A linkage of the actuator (606) can interconnect the actuator (604) and a slide bar (608). The slide bar (608) can carry, for example, two pairs of switchable contacts (610) spaced apart from each other. One of the pairs of switchable contacts (610) connects and disconnects a circuit path between a first group of auxiliary terminals (612) and rigid terminal members (614) that extend from the respective terminals (612) and each carries a respective stationary contact for coupling and decoupling with the first group of switchable contacts (610). The other pair of switchable contacts (610) connects and disconnects a circuit path between a second group of auxiliary terminals (616) and rigid terminal members (618) that extend from the respective terminals (616) and each carries a contact respective stationary for coupling and decoupling with the second group of switchable contacts (610). By joining or linking the actuator lever (620) of the auxiliary contact module (602) to the actuator lever (510) of the circuit breaker module (500) with a pin or a wedge, for example, the actuator (604) of the auxiliary contact module (602) can be moved or interrupted simultaneously with the actuator (508) of the circuit breaker module (500). A) Yes, the auxiliary connections can be connected and disconnected together, with a primary connection established through the circuit breaker module (500). For example, when the primary connection established through the module (500) supplies power to an electric motor, an auxiliary connection to a cooling fan can be carried out for the auxiliary contact module via one of the groups of terminals (612). ) and (616), so that the fan and motor will be turned on and off simultaneously by the device (600). As another example, one of the auxiliary connections through the terminals (612) and (616) of the auxiliary contact module (602) can be used for remote indication purposes to signal a remote device regarding the state of the device, as open or close to connect or disconnect circuits through the device (600). While auxiliary contact features have been described in the context of an additional module (602), it is understood that the components of the module (602) could be integrated in the module (500), if you want Likewise, single-pole or multi-pole versions of such a device could be provided. Figures 25-27 illustrate an eleventh embodiment of a fuse-breaker device (650) including a circuit breaker module (500) and a monitoring module (652) coupled or configured in series to the housing (502) of the module (500) via the openings (516) (Figure 17) in the module (500). The monitoring module (652) may include a housing (654) generally complementary in shape to the housing (502) of the module (500). A sensor board (656) is located in the housing (652), and the flexible contact members (658), (660) are respectively connected to each of the ferrules (462), (466) (Figure 18) (442) (Figure 1) in the circuit breaker module (500) via, for example, the upper and lower solenoid contact members (557), (568) (Figure 18) that establish a parallel circuit path through the fuse bushes (462), (466). The sensor board (656) includes a sensor (662) which monitors the operating conditions of the contact members (566), (568) and sends a signal to an input / output element (664) energized by an on-board power supply such as a battery (670) . When operating conditions are detected predetermined with the sensor (662), the input / output element (664) sends a signal to an output signal port (672) or alternatively to a communications device (674) that communicates wirelessly with a general view system and remote response response (676) that alerts, notifies, and calls the maintenance personnel or responsible technicians to respond to the interruption and open fuse conditions to restore or re-energize the associated circuitry, with minimal downtime. Optionally, an input signal port (678) may be included in the monitoring module (652). The input signal port (678) can be interconnected with an output signal port (672) of another monitoring module, so that the signals from the multiple monitoring modules can be daisy chained together with a single device of communications (674) for transmission to the remote system (676). Interface plugs (not shown) can be used to interconnect one monitoring module to another in an electrical system. In one embodiment, the sensor (662) is a voltage sensing hook circuit that has first and second portions optically isolated from each other. When the primary fuse element (680) of the fuse (442) opens to interrupt the current path through the fuse, the sensor (662) detects the voltage drop across the terminal elements Ti and T2 (the members of Solenoid contact (566) and (558)) associated with the fuse (442). The voltage drop causes one of the portions of the circuit, for example, to latch high and provide an input signal to the input / output element (664). Sensor technology acceptable for the sensor (662) is available, for example, from SymCom, Inc. of Rapid City, South Dakota. While in the exemplary embodiment, the sensor (662) is a voltage sensor, it is understood that other types of sensors could be used in alternative modes to monitor and detect a fuse operating state (442), which includes without restriction sensors of current and temperature sensors that could be used to determine whether the primary fuse element (680) has been interrupted in an overcurrent condition to isolate or disconnect a portion of the associated electrical system. In a further embodiment, one or more sensors or transducers may be provided additional (682), internal or external to the monitoring module (652), to collect data of interest with respect to the electrical system and the load connected to the fuse (442). For example, the sensors or transducers (682) may be adapted to monitor and detect vibration and displacement conditions, mechanical stress and voltage conditions, acoustic emissions and noise conditions, thermal imaging and thermographic states, electrical resistance, pressure conditions, and conditions of humidity in the vicinity of the fuse (442) and loads connected. The sensors or transducers (682) may be coupled to the input / output device (664) as signal inputs. Video and surveillance image formation devices (not shown) can also be provided to supply video data and inputs to the input / output element (664). In an exemplary embodiment, the input / output element (664) can be a microcontroller having a microprocessor or equivalent electronic package that receives the input signal from the sensor (662) when the fuse (442) has operated to interrupt the path of current through the fuse (442). The input / output element (664), in response to the sensor input signal (662), generates a data packet in a predetermined message protocol and sends the data packet to the signal port (672) or to the communications device (674). The data packet can be formatted in any desirable protocol, but in an exemplary embodiment it includes at least one fuse identification code, a default code, and a position or address code in the data packet, so that the fuse which is operating can be easily identified and its status confirmed, along with its location in the electrical system by the remote system (676). Obviously, the data packet could contain other information and codes of interest, including without restriction system test codes, data acquisition codes, security codes and the like, which are desirable or advantageous in the communications protocol. Additionally, the signal inputs from the sensor or transducer (682) can be inputs of the input / output element (664), and the input / output element (664) can generate a data packet in a predetermined message protocol and send the data packet to the signal port (672) or to the communications device (674). The data package may include, for example, codes related to vibration and displacement conditions, mechanical stress and pressure conditions, acoustic and noise emission conditions, thermographic and thermal image states, electrical resistance, pressure conditions, and humidity conditions in the vicinity of the fuse (442) and connected charges. The video and image data, supplied by the image and surveillance devices (682) can also be provided in the data packet. Such data can be used to solve problems, diagnose, and log events for detailed analysis, to optimize the largest electrical system. The data packet transmitted from the communication device (674), in addition to the data packet codes described above, also includes a unique transmitter identifier code, so that the general view and response send system (676) can identify the particular monitoring module (652) that is sending a data packet in a larger electrical system having a large number of monitoring modules (652) associated with a number of fuses. As such, the precise location of the circuit breaker module (500) affected, in an electrical system can be identified by the general view and response sending system (676) and communicating to the corresponding personnel, together with other information and instruction to quickly restore the affected circuitry when one or several of the modules (500) operate to disconnect a portion of the electrical system. In one embodiment, the communications device (674) is a low power radio frequency (RF) signal transmitter that digitally transmits the data packet in a wireless manner. Therefore the placement of cables from point to point in the electrical system for purposes of monitoring fuses is avoided, although it is understood that the placement of cables from point to point could be used in some embodiments of the invention. Additionally, while a low power digital radio frequency transmitter has been specifically described, it is understood that other known communication schemes and equivalents could be used alternatively, if desired. Status indicators and the like such as light emitting diodes (LEDs) can be provided in the monitoring module (652) to locally indicate a fuse that is operating (442) or a disconnect condition interrupted Thus, when the maintenance personnel arrives at the site of the circuit breaker module (500) containing the fuse (442), the status indicators can provide identification of the local state of the fuses associated with the module (500). Additional details of such monitoring technology, communication with the remote system (676), and response and operation of the system (676) are described in commonly owned U.S. Patent Application Serial No. 11 / 223,385 filed September 9, 2005 and entitled "Mounting, Equipment, and Monitoring Method". Protector Circuits. While the monitoring features have been described in the context of an addition module (652), it is understood that the module components (652) could be integrated into the module (500) if desired. Likewise, single-pole or multi-pole versions of such a device could be provided. Additionally, each of the monitoring module (652) and the auxiliary contact module could be used with a single circuit breaker module (500) if desired, or alternatively it could be combined into an integrated device with single pole or multiple capacity poles Figure 28 is a side elevational view of a portion of a twelfth embodiment of a fuse breaker module (700) that is constructed similarly to the breaker module (500) described above, but includes a bimetallic overload element (702) in place of the solenoid previously described. The overload element (702) is made of strips of two different types of metallic or conductive materials having different thermal expansion coefficients, joined together, and an alloy of strength attached to the mechanical elements. The strength alloy may be electrically isolated from the metal strips with insulating material, such as a double cotton coating in an exemplary manner. During use, the resistance alloy strip is attached to the contact members (557) and (558) and defines a high resistance parallel connection through the ferrule bushes (462) and (466) (442). The resistance alloy is heated by the current flowing through the resistance alloy and the resistance alloy, in turn heating the bimetallic strip. When a predetermined current condition approaches, the different rates of thermal expansion coefficients in the bimetallic strip cause the overload element (702) to bend and move the interrupter bar (545) to the release point, where the spring loaded actuator (508) and the slide bar (456) are moved to the open positions for disconnect the circuit by means of the fuse (442). The module (700) can be used in combination with other modules (500) or (700), auxiliary contact modules (602), and monitoring modules (652). Single-pole and multi-pole versions of the module (700) can also be provided. Figure 29 is a side elevational view of a portion of a thirteenth embodiment of a fuse circuit breaker (720) that is constructed similar to the circuit breaker module (500) described above, but includes an electronic overload element (722) that monitors the flow of current through the fuse thanks to the contact members (557) and (568). When the current reaches a predetermined level, the electronic overload element (722) energizes a circuit to supply power to the solenoid and interrupt the module (720) as described above. The electronic overload element (722) can also be used to reset the module after an event of interruption The module 702 can be used in combination with other modules 500 or 700, auxiliary contact modules 602, and monitoring modules 652. Single-pole and multi-pole versions of the module (700) can also be provided.
