Abstract
Multi-pole circuit breakers are joined together to form a common assembly. The individual poles are in the form of compact circuit breakers having a pair of separable contacts controlled by a single externally-accessible operating handle. The individual circuit breakers are riveted together and are keyed such that the contacts open and close in unison. The individual handles are interlocked together by means of a unitary plastic handle tie.
