ABSTRACT:
A multi-pole excess current circuit breaker assembly has a plurality of single-pole circuit breakers. In each of the latter the electric contacts are openable by a spring-loaded tripping mechanism actuated by a release lever as the release lever is moved from a first position to a second position by an excess current responsive device. The actuated tripping mechanism moves the release lever from the second position to a third position. The release levers of all the single-pole circuit breakers are operatively interconnected by a one-piece coupling member which is fixedly attached to one of the release levers, but is coupled to the others with a clearance, so that when excess current flows through the contacts of one of the single-pole circuit breakers, the release lever of the latter will move the release levers of the other single-pole circuit breakers only when it is displaced from the second position to the third position by the tripping mechanism of that single-pole circuit breaker through which the excess current flows.
