ABSTRACT OF THE DISCLOSURE In a circuit breaker undervoltage release device, a spring powered trip slide is held in a latched position by a latch lever while the plunger of a solenoid is magneti- cally held in a seated position against the bias of a calibrated return spring. In the event of an undervoltage condition, the spring retracts the plunger, causing the latch lever to release the trip slide, which then moves to trip the breaker. Opening movement of the breaker mechanism first actuates a reset lever to load a reset spring and then returns the slide to its latched position. As the latch lever regains latching control of the slide, the reset spring discharges to snap the plunger to it- seated position.
