Abstract (en)
An enclosed magnetothermal electric circuit breaker, comprising a containment body that contains a plurality of movable electrical contacts, which are in parallel and move synchronously, and of fixed contacts with corresponding arc quenching chambers, a mechanism for actuating the movable electrical contacts, a thermal tripping mechanism and an electrical protection device associated with a magnetic tripping mechanism, and a connection means for the external electrical connections. The actuation mechanism allows the movable electrical contacts to reach a stable position that is extremely close to the fixed contacts and then trip, from that position, onto the fixed contacts, closing the circuit breaker, regardless of the force and speeds applied to the actuation handle. <IMAGE>
