Abstract (en)
[origin: EP1953787A2] The device (1) has an actuating mechanism (7) displacing a mobile arc switching electrode (60) to open electric contacts (4, 6). A thermal disconnector (9) e.g. protective fuse, is connected in series between the electrode and a connecting lug (51). The disconnector is disabled when an electric arc (100) is switched between connecting electrodes (40, 50). The disconnector is passed from a closed electrical state to an open electric state when electrical short-circuit alternating current is passed into the disconnector, where energy of current is lower than an energetic triggering threshold.
