description The invention relates to an arrangement for overload protection of overvoltage protection devices, consisting of at least one type II surge arrester with or without a thermal disconnecting device that responds in the event of an of overload. According to the invention, a switching unit free of movable contacts is connected in series with the at least one surge arrester and structurally combined therewith, which switching unit has at least two fixed narrow spaced switching contacts, wherein the spacing of the switching contacts is specified in such a way that in the event of every surge current or discharge process, the switching device changes into a quasi-closed state because of the arc formed; whereas in the idle state, the voltage of the connected mains drops at the switching device, with the surge arrester arranged in series remaining free of leakage current.
