ABSTRACT:
A neutral line circuit interrupter having a switch in the neutral voltage line to trigger the interrupter upon the occurrence of a predetermined event to disconnect the line voltage from the load. Both contacts of the switch are at the identical, neutral voltage level so that the switch is not subject to a high voltage and can be used in remote locations where the presence of a high voltage would be undesirable.
