Definitions
- the invention relates to a circuit breaker according to the preamble of the claim
- Circuit breakers are known which are used in switchgear for the distribution of electrical
- the circuit breakers can either be fixed, in a drawer or as
- Plug-in NH fuse strips are also frequently used, which are arranged one above the other and each have a height of 50 mm.
- DE 4305746 shows and describes a circuit breaker arrangement which is detachably housed in a housing. With this load switch arrangement, connection contacts are also provided and fuses are arranged.
- a switchable fuse switch for low voltage systems is shown and described in DE 4102143, which has at least one fuse set.
- the object of the invention is to provide a protective device according to the preamble of claim 1, which combines the advantages of NH fuse strips and known circuit breakers and can be used universally.
- the object of the invention is characterized by the characterizing features of
- Fig. 1 is a schematic overall perspective view of a
- FIG. 2 is an overall perspective view of a circuit breaker with the cover removed
- Fig. 3 shows another overall perspective view of a
- Fig. 4 is an enlarged perspective partial view according to the right
- FIG. 5 shows a further enlarged perspective partial view according to the left part of FIG. 2,
- Fig. 6 is a plan view of an alternative circuit breaker
- Fig. 7 is a schematic side view of the circuit breaker according to
- Fig. 6. 1 shows a control cabinet 20 with busbars 22, which are arranged vertically and in an insertion region 21 and for feeding several
- Circuit breaker 1 are provided.
- the busbars 22 are so-called
- the circuit breakers 1 are provided with plug contacts 7. At the side of everyone
- Circuit breaker is an outgoing connection 14 is provided on the
- Outgoing lines can be connected in a separate
- the circuit breaker 1 is in accordance with the invention as a plug-in cassette
- control cabinets which are provided with retractable fuse switch conductors can be converted with circuit breakers 1.
- circuit breakers 1 can also be replaced by fuse switch leads.
- Fig. 2 shows a circuit breaker 1 consisting of switch contacts, which include movable switch contacts 2a and fixed switch contacts 2b, with quenching plates 3, a switch lock 4 with an operating lever 5, an overcurrent and / or short-circuit release 6, and plug contacts 7 for load current. Furthermore, the circuit breaker 1 comprises an electronics module 8 for controlling an electronics release or overcurrent and / or short-circuit release 6.
- the slide-in cassette has a height of 50 mm and is therefore interchangeable with an NH fuse block.
- the slide-in cassette can also have the usual height of 250 mm.
- the switching contacts 2a, 2b are arranged flat next to one another on a plane arranged parallel to the floor level, which enables a relatively flat construction. That the switching contacts 2a, 2b are not arranged one above the other or on a plane perpendicular to the floor plane, which in this case would exceed the overall height of 50 mm.
- the axis of rotation of the switching shafts of the movable switching contacts 2a are arranged perpendicular to the floor plane and aligned in a row.
- thermomagnetic release with a bimetal or a quick release with a hinged anchor or immersion anchor or the like.
- the switching shafts of the switching contacts 2a for transmitting the switching mechanism drive are connected to one another with a coupling rod 9, as shown in particular in FIG. 3. 4 shows, the coupling rod 9 performs a linear movement, which is indicated by the double arrow.
- the articulated pieces 38 arranged between the coupling rod 9 and the movable switching contacts 2a each perform a rotary movement.
- connecting rails 13, which are arranged between the fixed switching contacts 2b and the outgoing connections 14, are embedded in an insulating material duct 15.
- the connecting rails 16, which are arranged between the movable switching contacts 2a and the plug contacts 7, are arranged in a bridge-like manner over the insulating material duct 15.
- At least one auxiliary switch 17 can be mounted in the front of the plug-in cassette, which is connected to a switching cam of the switching shaft 31a of one of the movable switching contacts
- An undervoltage or shunt release can also be present.
- An active connection 18 is arranged between the switching lock 4 and the overcurrent and / or short-circuit release 6, as shown in broken lines in FIG. 2.
- the switch contacts can alternatively be designed as rotary contacts 10, as shown in principle in Fig. 6 or 7.
- the axis of rotation of the rotary contacts 10 is arranged in the plug-in direction or insertion direction 23, as shown in FIG. 6.
- the switch lock 11 is arranged between the front plate 12 and the rotary contacts 10, the rotary contacts having a common axis of rotation or switching shaft 31b.
- connections 34 and 35 are arranged on different levels, which are provided with fixed switching contacts 30b.
- the movable switching contacts 30a are arranged diametrically opposite each other, as shown in FIG. 7, around the common switching shaft 31.
- the quenching plates 32 are integrated in a housing together with the fixed switching contacts 30b, the movable switching contacts 30a and the switching shaft 31.
- control button 5 is designed as a rocker arm.
- the circuit breaker 1 can also be equipped with a Fl protection.
- elements can be integrated in the circuit breaker that contain the functionality of a contactor.
- three contactor contacts with a magnetic drive are additionally integrated in the housing.
- the present invention is not limited to the embodiments described above, but also encompasses all embodiments having the same effect in the sense of the invention.
- the invention can be used with Connecting strand, the strand is flexible, or conductor tracks
- a circuit breaker without a protective function is also conceivable, which is only used as an isolator or load isolator.
- circuit breaker can e.g. than can be provided without an overcurrent release, without a quick release but also without a switch lock.
- Insulation duct 15 Insulation duct 15
