Abstract
A high-current multipole circuit breaker is made up of standard poles juxtaposed in a molded case. At least two adjacent poles are twinned, that is to say electrically arranged in parallel and connected to a common connecting strip. The connecting strips of the other poles are widened, so as to partially overlap the immediately adjacent twinned pole. In this way, the circuit breaker rating is higher than that of the individual poles which make it up.
