Abstract

The invention relates to an overvoltage protection device with a short-circuit function for protecting installations and persons for low-voltage installations, wherein at least one overvoltage protection element and a thermally activatable short-circuit device are arranged in a common housing. The device is designed to be inserted into an NH fuse part, and the common housing is designed with contact blades so as to be spatially analogous to a NH fuse link.
