ABSTRACT:
An arrangement is provided for interconnecting a set of two or more circuit breakers such that tripping of one will cause concurrent tripping of the others. A coupler adapted to be placed in a recess defined by the abutting side walls of two adjacent breakers is engageable with trip members in both of the associated breakers and provides operative interconnection between the two breakers. Only one of the breakers of the set need be provided with an operating handle which can be used to turn all of the breakers "on" and "off" in unison.
