Abstract
The device comprises means for applying a DC voltage U as a function of the voltage taken from the terminals of a fuse between a fixed electrode and a movable electrode forming together a capacitor. The movable electrode is urged towards the fixed electrode by an electret fast to the latter and in the opposite direction by a magnet and by the voltage U. As soon as this voltage exceeds a threshold corresponding to the rupture of the fuse, the movable electrode swings over and closes a switch for warning purposes.
