Abstract

A circuit breaker comprises a magnetic trip actuator comprising an armature movably supported on a stationary non-magnetic support pin, and permanent magnet means supplying magnetic flux that operates through a magnetic supporting frame to maintain the armature in an initial position. When released, the armature moves in an opening in the frame to actuate the breaker mechanism to trip the breaker. Upon movement of an operating handle structure to a reset position to reset the mechanism of the circuit breaker, the handle structure engages a pivoted reset member to move the reset member against the armature to thereby reset the armature in the initial position.
