Abstract

See full text

A multi-pole circuit interrupter configured to be coupled between an AC source and an electric load electronically detects a hazardous condition associated with energizing of poles and responds to overcome the hazardous condition using a solenoid. The multi-pole circuit interrupter comprises a first switch to energize a first pole on a phase A conductor of the multi-pole circuit interrupter and a second switch to energize a second pole on a phase B conductor of the multi-pole circuit interrupter. The multi-pole circuit interrupter further comprises an electronic solid-state circuit coupled to the phase A conductor and the phase B conductor to detect a line voltage variation and control a current to a device in response to trip an energized pole among the first pole and the second pole if only one of the first pole and the second pole is energized when a user controls a tie bar to turn ON or turn OFF the multi-pole circuit interrupter or when a trip bar fails to trip one of the first pole and the second pole.
