Abstract
An improved solenoid having an enhanced magnetic field and failsafe operation is provided, wherein a primary winding and a secondary winding are constructed such that the combined force imparted on a plunger by both windings energized together is greater than the sum of the forces imparted by the primary and secondary windings energized separately, resulting in a smaller solenoid capable of providing a predetermined force, and providing a solenoid capable of tripping a circuit interrupting latch even if one of the windings is broken.
