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.
