TH14571B - Distance of molded case low voltage circuit breaker - Google Patents

Abstract

The range of a molded low-voltage circuit breaker is realized through a standard single-pole device with a casing made of insulating cast material (11) containing various contacts and a debug chamber. A multi-pole circuit breaker can be performed by device arrangement. Single pole type (10) multiple in a enclosure (31) The arrangement between unipolar devices (10) is the gap obtained by the splitter (32) to obtain the assembly pattern determined by the width of the The cover of a single-pole phase-splitter circuit breaker (32) consists of an overpressure actuator (45).

Claims (9)

1. Low voltage double shielded, multi-pole circuit breaker, made up of a standard single-pole open circuit device (10), encapsulated in a molded joint enclosure (31) and a device. Each unipolar (10) consists of a parallel six-sided insulating box (11) with two large parallel and opposite (18,19) facades and two small parallel and opposite facades. Two (20,21) discs and also have a movable contact (12) that is rockable on the axis (17), which is perpendicular to the large front plan. And will work together the stationary contact (13,14) adjacent to the small faceplate supporting the junction (22,23) connected to the stationary contact (13,14) type device Several unipolar (10) characters are arranged in size in a casing (31) in accordance with their large frontal layout. The moving contacts are arranged into tabs (12) that work together, two fixed contacts (13,14), each attached to a small (20,21) face plate for This resulted in the opening of a dual circuit in the suspension chamber (15,16) of a single-pole device (10).

The two end fittings are attached to the wall (30) of the upholstery (31) by means of a sheet. Its large front (18) to allow for the preservation of the assembly form defined by the single-pole circuit breaker (26) and the single-pole device (10) being bolted together as a single piece. The insertion of the separator (32,38) or the wedge, which defines the space between adjacent devices (10). 2. The circuit breaker according to claim 1 shall be in such a form that the width of the enclosure (31) shall be 35 m m. The width of the enclosure of the different circuit breaker shall be in The distance that is a product of 35m m. And the connection point (22,23) is located where the distance is 35mm. 3. Circuit breakers according to claim 1 will be in such a way that the splitters (32,38) will be in the form of a slab with a groove (34) or a passageway for the control beam and / or wire. Reinforced protrusion between the back plate (24) and the front plate of the box (11) 4.The circuit breaker according to claim 3 will be in such a way that the splitter (32) has a positioning pin (37) held in a corresponding hole arranged in the large front (19) of the Box (11) to position the box with the rest 5.The circuit breaker according to claim 4 will be such that the splitter (32) will have a channel (41) that is connected through hole (48) to the box (11) of the unipolar device (10). And in such a way that the actuator (44,45) in response to the overvoltage available in the cavity (41) controls the mechanism (25) to open the circuit breaker when the overvoltage is greater than the Hold on 6. The circuit breaker according to claim 5 will be in such a way that the actuator consists of a piston (44) mounted for the movement in a cylinder located in the cavity (41). 7. The circuit breaker according to claim 5 or 6 will be in such a way that corridor (51) is formed by a set of rivets tubular rivets that provide a contact link between the cavity (4) and Box (11) of non-adjacent unipolar devices 8. The circuit breaker according to claim 1 will be such that the operating mechanism (25) is the operating mechanism with the rocker knob (29) enclosed in the casing (31) over the unipolar device (10). The mechanism is filtered by two large flanges (26), two large facades (18,19) of the unipolar device (10) and such flanges (26) with distance. The distance between them corresponding to the width of the device (10) is fixed to a single pole device. 9. Circuit breakers according to claim 8 are in such a way that the contact tabs (13) of the unipolar devices (10) of the circuit breaker are rotated to the operating mechanism. (25) like all unipolar devices
