ABSTRACT:
A limiting circuit breaker with a molded case comprises an overpressure actuator which, when an overpressure occurs in the arc extinguishing chamber due to the action of an arc drawn by the electrodynamic repulsion of the contacts, brings about actuation by a piston, subjected to this overpressure, of the circuit breaker trip bar. The overpressure actuator forms an almost leaktight assembly.
