Abstract:
A circuit breaker assembly includes a plurality of controllable circuit breakers. Each of the controllable circuit breakers includes separable contacts, an operating mechanism structured to open and close the separable contacts, a trip mechanism cooperating with the operating mechanism to trip open the separable contacts, a first line terminal, a second load terminal, and at least a third terminal. The trip mechanism is structured to trip open the separable contacts responsive to a signal from the third terminal. The circuit breaker assembly also includes a toggle electrical switching apparatus that includes separable contacts electrically connected between the third terminal and ground, and a toggle operating member structured to open and close the separable contacts of the toggle electrical switching apparatus.
Abstract:
A circuit interruption device includes a support, a set of separable contacts, a first member movable between an OFF position and an ON position, a second member, and a transport mechanism that includes a shape memory alloy element. When the first member is in the OFF position, the second member is in an extended position, the shape memory alloy element is in its first shape, and the first surface and the another first surface are engaged with one another and resist movement of the first member away from the OFF position. Responsive to an electrical pulse, the shape memory alloy element transforms into its second shape and moves the first member toward the ON position. When the second member is in the extended position, the another second surface engages with the second surface to resist movement of the first member away from the ON position.

Abstract:
An electrical switching apparatus includes a housing, separable contacts within the housing, and an operating mechanism structured to open and close the separable contacts. The operating mechanism includes a push/pull operating handle and a remotely controllable actuator. The electrical switching apparatus also includes a trip mechanism cooperating with the operating mechanism to trip open the separable contacts in response to a trip condition or remotely open the separable contacts when closed. The remotely controllable actuator is structured to move the push/pull operating handle in order to remotely close the separable contacts when opened or remotely reset the separable contacts when tripped open.
Abstract:
A circuit interrupter apparatus for plug-in connection to a panel board. The circuit interrupter apparatus includes a line terminal for plug-in connection with a line power member provided as part of the panel board, a load terminal for plug-in connection with a load power member provided as part of the panel board, a moveable contact moveable between a closed position, where the line terminal is electrically coupled to the load terminal, and an open position, where the line terminal is not electrically coupled to the load terminal. The circuit interrupter apparatus also includes a sensor module for a plug-in connection to a number of signal conductors provided as part of the panel board. The sensor module detects whether the moveable contact is in the closed position or the open position and output a signal to at least one of the signal conductors indicating a current position of the moveable contact.
