Abstract

The invention relates to an overvoltage protection device, comprising at least one surge arrester and one switchgear assembly, which is connected in series to the surge arrester and which can be triggered thermally, wherein the aforementioned components form a structural unit, and the thermal tripping means is arranged in the area of the expected heating up of the surge arrester when overloaded. According to the invention, the thermal tripping unit is configured as a stop element through which operating current or surge current does not flow. In the event of thermal overload, the stop element opens a releasing device of the switchgear assembly, wherein said switchgear assembly has an increased self-extinguishing capacity.
