Abstract

A magnetothermal electric circuit breaker, comprising a casing which contains at least two fixed electrical contacts in a parallel arrangement which are separated by an insulating partition, each contact being associated with an arc quenching chamber, an electrical protection component associated with a magnetic tripping mechanism, a mechanism for the actuation of at least two electrical moving contacts in a parallel arrangement, a thermal tripping mechanism, a connection means for the external electrical connections; each one of the electrical moving contacts includes a double contact.
