ABSTRACT OF THE DISCLOSURE An undervoltage tripping unit for a power line circuit breaker features a holding solenoid and a boosting solenoid having their associated plungers coupled to move together so as to be retracted against the force of plunger biasing springs when both solenoids are energized. Release of the plungers from the retracted position is used to trip the associated power line circuit breaker when the line voltage falls below a tripping voltage level. One solenoid serves as a holding solenoid and is continuously coupled to the circuit breaker power input terminals. The other solenoid serves as a booster solenoid and is energized through a plunger-actuated switch so as to be de-energized when the plungers are fully retracted or in a position proximate thereto.
