DEVICE FOR INTERRUPTING NON-SHORT CIRCUIT CURRENTS ONLY, IN PARTICULAR DISCONNECTOR OR EARTHING SWITCH
The present invention relates to a device for interrupting non-short circuit currents only, and in particular relates to a disconnector, more particularly high voltage disconnector, or to an earthing switch, more particularly make-proof earthing switch, and further relates to a low voltage circuit breaker. The device comprises at least two contacts movable in relation to each other between a closed state and an open state and defining an arcing region, in which an arc is generated during a current interrupting operation and in which an arc-quenching medium comprising an organofluorine compound is present. According to the application, a counter-arcing component is allocated to the arcing region, the counter-arcing component being designed for counteracting the generation of an arc and/or being designed for supporting the extinction of an arc.
