Abstract
An electric operator having a reciprocally mounted actuator is adapted to be mechanically coupled to an operating handle from a molded case circuit breaker or a molded case switch for moving the operating handle between an open position or, alternatively, to a closed position. The electric operator includes an electric motor for driving the actuator and allowing the circuit breaker to be controlled from a remote location and a mechanical crank assembly which alternatively allows for manual operation of the actuator in the event of a loss of electric power to the electric motor.
