ABSTRACT:
A handle mounted externally on the door of a sealed enclosure operates a mechanism on the inner side of the door which controls the opening and closing of a circuit breaker located within the enclosure. The handle has a detented OPEN and AUTO position and a spring returned CLOSE position. When the handle is in the OPEN position an extensor assembly moves a contact member perpendicularly away from the inner surface of the door to operate a mechanical trip plate of the associated circuit breaker. When the handle is moved to the CLOSE or AUTO position a bumper member is moved by the mechanism in a direction parallel to the inner surface of the door to selectively activate either of two switches located on a switch bracket resiliently mounted upon the associated circuit breaker. The door can be hinged from either side. The handle can be padlocked in the OPEN or AUTO position but not in the CLOSE position.
