ABSTRACT:
A circuit breaker characterized by a circuit breaker structure having separable contacts and a releasable mechanism which mechanism is retained in untripped position by a latch including a rotatable trip bar. A solenoid, that is operable automatically in response to overload current conditions, is located adjacent to the trip bar and has a plunger movable parallel to the axis of the trip bar. A lever is disposed between the plunger and the trip bar to translate longitudinal motion into rotational trip bar motion.
