ABSTRACT:
A circuit breaker includes separable contacts, an operating mechanism structured to open and close the separable contacts, a molded enclosure comprising a first molded portion and a second molded portion, a plurality of thread cutting screws fastening the first molded portion to the second molded portion, and a plurality of machine screws. The first molded portion and the second molded portion cooperate to form a plurality of exterior walls. The exterior walls define an interior volume, which encloses the separable contacts and at least a portion of the operating mechanism. The machine screws extend within and reinforce the exterior walls and restrict expansion of the exterior walls away from the interior volume.
