ELECTRICAL SWITCHING APPARATUS AND TRIP ACTUATOR ASSEMBLY THEREFOR

A trip actuator assembly is provided for an electrical switching apparatus, such as a circuit breaker. The trip actuator assembly includes a trip actuator with an actuating element, which is movable among unactuated and actuated positions corresponding to separable contacts of the circuit breaker being closeable and tripped opened in response to a trip condition, respectively. The trip actuator is disposed at a mounting portion of a frame. An interface assembly is movably coupled to the frame and includes an interface element disposed between the actuating element of the trip actuator and a portion of the circuit breaker operating mechanism. When the actuating element moves from the unactuated position toward the actuated position, it engages and moves the interface element, thereby moving the operating mechanism to trip open the separable contacts. The frame secures the trip actuator assembly in a desired orientation within a corresponding one of the housing compartments.
