Abstract: Circuit breakers are configured with line terminal geometry that drives the current from a terminal input in a direction that can reduce electromagnetic forces and that can also or alternatively include an arc chute assembly that can reduce repulsive electromagnetic forces to improve the operating level of withstand current (Icw).

Abstract: A limiter includes a housing having a first surface and a second surface, a line terminal, a load terminal, a fusible conductor electrically connected between the line and load terminals and an indicator button disposed proximate the first surface. The button includes a first end and a second end having a first opening, a second opening and a conduit therein between the first and second openings. The fusible conductor passes from the first terminal, through the first opening, through the conduit, through the second opening, and to the load terminal. A spring biases the button away from the first surface. The fusible conductor, when electrically connected between the line and load terminals, holds the second end proximate the first surface. The spring, when the fusible conductor is electrically disconnected from one or both of the terminals, moves the button away from the first surface and toward the second surface.

Abstract: 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.
