Abstract
An operating mechanism comprises an operating handle movable between on and off positions, the operating handle extending substantially up at a point between said on and off positions; a crank for controlling a contact arm of a circuit breaker to cause the contact arm to move between open and closed positions when the crank moved; mechanism springs connected between the operating handle and crank so that the crank moves when the mechanism springs are discharged and when the operating handle is moved between on and off positions; a trip latch restraining the mechanism springs from discharging unless moved; and a trip lever having a lever arm, the trip lever being biased by a tripping spring to cause the trip lever to extend substantially up from the operating mechanism and move the trip latch and discharge said mechanism springs unless the trip lever is prevented from rotating under the influence of said tripping spring.
