Abstract
An operating mechanism assembly used within molded case circuit breakers employing electronic trip units interconnects the operating mechanism with the circuit breaker movable contact arms by means of a slotted-cam arrangement. The slotted-cam optimizes the manual closing of the movable contact arms by controllably over-centering the circuit breaker operating mechanism springs.
