Abstract
A remote actuator for an enclosed molded case circuit breaker or disconnect switch utilizes an actuator cable connection with the circuit breaker operating handle in a "pull-pull" arrangement. The cable is arranged in an endless loop between the actuator handle and the circuit breaker operating handle. Moving the actuator handle in a first direction pulls the circuit breaker operating handle to its ON position while moving the actuator handle in an opposite direction pulls the circuit breaker operating handle to its OFF positoin. A retractable handle extender on the actuator handle increases the torquing force applied to the actuator handle and the circuit breaker operating handle.
