Abstract
A resettable contact closing device opens a load circuit connected to a power line protected by a ground fault interrupter circuit, if the neutral conductor is broken. The contacts are closed by a mechanical reset actuator only if a solenoid is energized by a potential proportional to the line-to-neutral voltage to hold the actuator in a contact closing position. If the neutral conductor is broken, the solenoid will not be energized and the contacts, and hence the power line to the load circuit, will be opened.
