Abstract (en)

[origin: DE19702116A1] A protecting device has a disconnecting contact (13) connected to the load current line (2) and actuated by an electromagnetic system (9). A shunt circuit leads from the side of the disconnecting contact (13) opposite to the battery to an earth line (3), via a diode polarised in the blocking direction. The earth line (3) crosses or extends through the ferromagnetic circuit of the electromagnetic system (9). When the battery terminals are connected to reverse poles, a high short-circuit current flows through the diode (23) and induces an excitation in the ferromagnetic circuit (11, 12) of the magnetic system (9), lifting the armature (12) and opening the disconnecting contact (13).
