Abstract

2069505 9206484 PCTABS00011 An accessory module (104) for use with a circuit breaker (10) is configured for mounting to the breaker, and has rotor system (142) which follows the movement of the circuit breaker blade (24) in the breaker by means of a coupling member (118) passing through a passage (110) in the circuit breaker wall. A portion of the rotor is configured as a cam (162) operating a switch (152) in the module, the switch thus giving a reliable indication of the position of the breaker blade. The breaker is preferably of the type which carries a trip lever (50) carried on the breaker blade and mounted for slight movement thereon, and the rotor is preferably coupled to the trip lever. A solenoid (148) within the accessory module is disposed to engagingly rotate the rotor when energized, this rotation being coupled to trip the breaker to provide for remote tripping. Since the trip lever is carried with the breaker blade, blade position is monitored by the switch.
