Abstract:
A circuit breaker having a manual opening resistant feature comprising:a housing, at least one stationary electrical contact mounted in the housing, a movable contact assembly having at least one movable electrical contact movable between open and dosed contact positions with the at least one stationary electrical contact, a bushing extending from the housing and having an open end, a generally cylindrical pushbutton having a longitudinal axis and having a top surface, the pushbutton slidingly received in the bushing between an outer position with the top surface spaced out of the open end of the bushing and an inner position generally even with, the open end of the bushing, the pushbutton operatively coupled to the movable contact assembly for moving the movable contact into the closed contact position in response to movement of the pushbutton to the inner position and for moving the movable contact into the open contact position in response to movement of the pushbutton to the outer position, a reaction surface formed in the circuit breaker and an opening formed in the pushbutton providing access to the reaction surface whereby a contact opening force can be applied to the reaction surface.
