    摘要： The toggle mechanism (13) of a circuit breaker (1) is connected at one end to the pivoted contact arm (33) and at the other end to a pivoted latch lever (53) which is engaged to latch the toggle mechanism (13) by a latch member (85) pivoted for movement in a plane (107) perpendicular to the plane (105) of the toggle mechanism (13). The latch member (85) serves as an armature (93) for a trip motor (119) energized by a trip circuit (139) responsive to an arc fault and/or a ground fault to unlatch the toggle mechanism (13) and trip the circuit breaker (1) open. The latch member (85) is also tripped by a helical bimetal (109) responsive to persistent overcurrents and coupled to the latch member through an ambient compensator bimetal (113) cantilevered from the latch member (85). A flexible shunt (111) connected between the helical bimetal (109) and contact arm (33) passes through an extension (143) of the magnetic circuit (124) of the trip motor (119) to generate a magnetic field of sufficient strength to trip the latch member (85). A flexible shunt (111) connected between the helical bimetal (109) and contact arm (33) passes through an extension (143) of the magnetic circuit (124) of the trip motor (119) to generate a magnetic field of sufficient strength to trip the latch member (85) instantaneously in response to a short circuit.

    摘要： Electrical switching apparatus (1) such as a power circuit breaker, network protector or switch has a self-supporting operating mechanism module (17) including a cage (95) formed by a pair of side plates (97) rigidly clamped in spaced relation by spacers (99). The cage (95) supports all of the operating mechanism components (18,107,109,113) including a helical compression close spring (18) mounted fully between the side plates (97) and coupled to a cam member (171) through a rocker (155) in a manner which maintains the forces longitudinal to the spring (18). The cam member (171) has a charging cam (173) with a charge profile (189a) for compressing the close spring (18) and a close profile (189b) through which the spring (18) drives the cam member (171) to effect a controlled release of stored energy to close the contacts of the apparatus. A close prop (223), spring biased to an unlatched position, is latched to secure the close spring (18) in the charged state by a latch assembly (225) reset by a reset lever (247) separate from the close prop (223) which in turn is reset by rotation of the cam member (171) during charging. An interlock (265) prevents release of the close spring (18) when the contacts (43) are closed or the trip release is actuated. An indicator (27) actuated by a driver (345) pivoted against the cam shaft (115) snaps from a DISCHARGED to a CHARGED indication as the close spring (18) becomes fully charged and the driver (345) drops into a notch (343) created by a flat on the cam shaft (115). A snap action open/closed indicator (29) for the switch contacts (43) is also provided. Both indicators (27,29) are pivotally mounted in a face plate (19) pinned to the side plates (97) and are connected to the operating mechanism by wireforms (349,381). The close and open push buttons (23,25) snap out to a common shaft (301) and have actuating fingers (305,309) which trigger releases in the operating mechanism (17). The close rotating shafts (213,239) are journaled solely in confronting apertures in the side plates (97). The cam shaft (115) is captured between bushings (117) seated in non-circular openings (119) in the side plates (97) thereby eliminating the need for any fasteners. Likewise, other parts (165) mounted between the side plates (97) and joined by pins (167) having enlarged heads (169) retained by the side plates (97) do not need retainers. Various shafts (451) extending between the side plates (97) have reduced diameter ends (457) of progressive lengths for successive insertion in one side plate (97z) to aid in assembly of the operating mechanism (17).

    摘要： A modular asynchronous contactor assembly (88) includes a contactor (90A-C) for each phase (A, B, C) or pole of an electrical device. The contactor assembly (88) is applicable as both a switching device and an isolation or load protection device. As such, each contactor (90A-C) is constructed so that each includes multiple contact assemblies (96A-C, 98A-C). Moreover, the contactors (90A-C) within a single contactor assembly (88) or housing can be independently controlled so that the contacts (96A-C, 98A-C) of one contactor (90A-C) can be opened without opening the contacts (96A-C, 98A-C) of the other contactors (90A-C) of the contactor assembly (88).

    摘要： An aircraft circuit breaker (1) includes a housing (3); separable contacts (47) mounted in the housing (3); a latchable operating mechanism (22) including a latch member (51) which when unlatched opens the separable contacts (47); and an overcurrent assembly (53) responsive to selected conditions of current flowing through the separable contacts (47) for unlatching the latch member (51) to trip the separable contacts (47) open. A movable and illuminable arc fault indicator (37) has a first ring portion (274) and second leg portions (271,273) internal to the housing (3). An arc fault actuator (119) which when energized moves one (271) of the second leg portions (271,273). An arc fault current assembly (39) responds to selected arc fault conditions of current flowing through the separable contacts (47) to energize the arc fault actuator (119) to move the second leg portions (271,273) internal to the housing (3) and the first ring portion (274) external to the housing (3). The arc fault current assembly (39) includes a light (135) for illuminating the first ring portion (274).
