Abstract
Single pole circuit breakers are connected in a modular array to provide up to four poles by means of a handle tie bar assembly. The circuit breaker operating handles are grooved to receive a metal interlocking pin and a plastic tie bar to cause the circuit breakers to move in unison. A locking clip arranged between one of the operating handle slots and the tie bar assembly prevents the circuit breakers from being turned from their OFF-to-ON or ON-to-OFF conditions.
