Abstract

An auxiliary device for opening a circuit breaker associated therewith following a remote opening command, comprising an insulating enclosure which contains fixed contacts and a corresponding moving contact, connection terminals, a fixed magnet on which a coil is wound and a moving magnet which can be coupled electromagnetically to the fixed magnet, comprising: actuation means which arc operatively connected to and actuated by the moving magnet; means for coupling to the circuit breaker which are operatively associated to the actuation means; a kinematic chain operatively connected to the means for coupling to the circuit breaker; means for interacting with the moving contact, which are operatively connected to the kinematic chain; means for providing a local visual indication of the open state of the circuit breaker following said remote opening command, actuated by the actuation means. <IMAGE>
