    摘要： An opening assist mechanism is for the cradle assembly of a circuit breaker including a housing enclosing separable contacts, and an operating mechanism for opening and closing the separable contacts. The operating mechanism includes a trip bar and a cradle assembly. The cradle assembly includes a first toggle link, a second toggle link pivotally coupled to the first toggle link by a first pivot, and a cradle member pivotally coupled to the second toggle link by a second pivot. The cradle member includes a third pivot and a latching portion structured to engage the trip bar when the cradle assembly is disposed in a position corresponding to the separable contacts being closed or otherwise closeable. The opening assist mechanism comprises an actuator, such as a kicker pin, disposed on the cradle member and structured to engage and move at least one of the first and second toggle links in response to an actuation of the operating mechanism. In this manner, the opening assist mechanism resists the tendency of the first and second toggle links to jam in an over-center configuration.

    摘要： A positive off mechanism for a circuit breaker includes a pair of positive off levers slideable in slots in the side plates and extendable into the path of the operating handle to prevent movement of the handle to the off position when the contacts are welded closed. The positive off levers are actuated by positive off links pivotally mounted to the side plates and coupled to the positive off levers by "dog bone" connections. The positive off links in turn are actuated by the toggle mechanism of the circuit breaker which collapses to open the contacts during normal circuit breaker operation, but which remains erect when the contacts are welded closed.

    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 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.
