Abstract (en)
[origin: EP1615247A1] The device has first and second fixed contacts for connection to the terminals of a circuit breaker, a contact path between the fixed contacts that carries current with the switch closed with a movable contact bridge with a first bridge contact forming a first contact point with the first bridge contact, a fore chamber with a first spark rail for accepting a spark formed when the first contact point opens and a quenching chamber connected to the fore chamber. A current path with no current with the switch closed contains the first spark rail and a current-limiting element. The quenching path is connected to the second fixed contact and the first spark rail is designed to receive a spark foot point from the first bridge contact. An independent claim is also included for a protection circuit with a circuit breaker.
