Abstract

The protection circuit has at least one discharge tube (5, 5'), which discharge tubes are connected between earth and a current conductor or which are connected between earth and in each case one current conductor (1, 2). In order effectively to protect sensitive components in the loads which are connected to the domestic installation, the connection of the discharge tube between earth and a current conductor is inserted downstream of the main switch (4) and upstream of the first load. In the event of overvoltages above a threshold value which is larger than temporary interference voltages in normal operation, but less than the maximum permissible voltage for the sensitive components, the discharge tubes (5, 5') trigger without any delay and short-circuit the current conductors via earth. The main switch (4) interrupts this short-circuit current and disconnects the discharge tubes and loads from the distribution line.
