Abstract

The invention concerns a double-motion circuit breaker comprising primary and secondary movable contacts slidingly mounted within primary and secondary holders, wherein the primary movable contact comprises a tulip and a contact cylinder attached thereto, and the secondary movable contact comprises a pin for engaging the tulip but no counter-contact for engaging the contact cylinder. The circuit breaker also has a non-linear linkage mechanism with a pin and slot mechanism, and a fixed dielectric shield provided on the secondary holder. During disconnection, the linkage mechanism is preferably arranged to move the pin more than the tulip, proportionally to their maximum stroke, so as to quickly bring the pin tip within the fixed dielectric shield, whereafter the tulip moves more than the pin. This circuit breaker is cheaper, lighter and can be disconnected more quickly.
