ABSTRACT:
A modular option deck is disposed adjacent the trip bar of the circuit breaker to facilitate the addition of circuit breaker options, such as an undervoltage trip device and shunt trip device to the circuit breaker. The option deck includes an aperture disposed adjacent the trip bar to allow the actuating lever or plunger from the option device to communicate with the trip bar. The option devices are mounted on brackets having diametrically opposite downwardly extending L-shaped depending arms, adapted to be received in any one of a plurality of sets of slots provided on the deck. The brackets are quickly and easily slid into the slots on the bracket and secured in place.
