    摘要： An electrical switching apparatus interface assembly provides remote actuation of the operating handle of a circuit breaker. The interface assembly includes the circuit breaker, a second switching apparatus, such as an actuating handle disposed in a remote location from the circuit breaker, a connector and an operating handle attachment including a handle-engaging segment for securely engaging the circuit breaker operating handle and an interfacing segment for receiving the connector. The actuating handle is operable between ON and OFF positions corresponding to ON and OFF positions, respectively, of the circuit breaker operating handle. The connector interfaces or links the circuit breaker to the actuating handle. In this manner, when the actuating handle is moved from the ON or OFF position, the connector moves the circuit breaker operating handle in a likewise manner.

    摘要： The movable contact arm of a circuit breaker is mounted on a pivot pin by a slot which extends generally transverse to the longitudinal arm of the contact arm, so that when the contacts are welded, initial motion of the circuit breaker operating mechanism to open the contacts is translated into pivoting of the contact arm about, and thereby breaking the weld. In a circuit breaker in which the contact arm is coupled to the operating mechanism through a cam mechanism which allows the contact arm to blow open in response to very high overcurrents, the slot extends generally longitudinally so that the cam mechanism translates initial movement of the operating mechanism into longitudinal movement of the contact arm to apply a shear force tending to break the weld.

    摘要： The handle of an electrical switch reciprocally movable in a slot in the switch housing is locked in a desired position by a locking mechanism which includes a base plate secured to the housing adjacent one end of the handle slot. A hasp member is hinged to the base plate at a hinge end for rotation about a hinge axis transverse to the path of reciprocal movement of the handle. The hasp member is rotatable between a locking position in which it overlaps the front end of the slot so that the handle cannot be moved away from the second end of the slot. A staple extending transversely from the base plate protrudes through an opening in the hasp member and has an opening for receiving one or more padlocks for locking the hasp member in the blocking position. In a second embodiment, the hasp member has a second opening through which the handle protrudes for locking the handle at the front end of the slot. Notches in arcuate fingers forming the hinge connection for the hasp member are engaged by sliding the hasp member axially on the hinge connection to latch the hasp member clear of the handle which allows unrestricted movement of the handle even with the switch mounted vertically.
