ABSTRACT:
A control circuit combined with a magnetically bistable solenoid armature provides a bistable undervoltage release function to a circuit breaker. The solenoid is fabricated from a material having high magnetic remnance and low coercivity. A first signal to the solenoid coil develops a high remnance flux to hold the armature against a spring force. A second signal, of opposite polarity and predetermined voltage, produces an opposing magnetic flux to cancel that retained by the solenoid. The armature then becomes extended under the influence of a charged spring to trip the breaker.
