Abstract (en)
A circuit-breaker with moulded casing (10) of the limiter type includes an overpressure actuator (26, 27) bringing about, when an overpressure appears in the disconnection chamber (13) under the action of an arc drawn by the electrodynamic repulsion of the contacts (11, 12), actuation by a piston (26), subjected to this overpressure, of the tripping bar (23) of the circuit-breaker. The overpressure actuator constitutes a quasi-sealed unit. <IMAGE>
