Abstract
A circuit breaker includes a plurality of poles that are connected with one another in parallel, and additionally includes a mutual connection connecting the poles with one another to isolate the trip units associated with the poles from any imbalance in the current flowing through the poles. Each pole includes a first conductor structured to be connected with a power source, a second conductor structured to be connected with an electrical load, and a pair of separable contacts that disconnectably connect the first conductor with the second conductor. The trip unit of each pole is configured to measure the current flowing through a given point of the second conductor, and the mutual connection connects the second conductors together at a connection point, the connection point of each second conductor being between the separable contacts and the given point.
