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. 1. An overvoltage protection device with short-circuit function for protecting persons and low-voltage system installations , the overvoltage protection device comprising:at least one overvoltage protection element as well as one thermally triggered short circuit device are arranged in a common housing; andwherein the device is designed to be inserted into an NH fuse base and the common housing is designed with contact blades be spatially analogous to an NH fuse element.2. The overvoltage protection device according to claim 1 , wherein the short circuit device is configured as a mechanical short-circuiter having a fixed part and a movable part claim 1 , wherein a sacrificial element is situated between the two parts which triggers or enables an irreversible relative motion of the parts once a predefined or predefinable It value is reached.3. The overvoltage protection device according to claim 1 , and further comprising a status indicator having a remote signaling function.4. The overvoltage protection device according to claim 3 , wherein a mechanically released pin forms the status indicator claim 3 , wherein the pin blocks the device from re-inserting into the NH fuse base when released.5. The overvoltage protection device according to claim 1 , wherein a parallel connection is provided in the common housing which consists of a series connection of voltage-switching element claim 1 , the sacrificial elements and the short circuit device in the first branch and at least one voltage-limiting element in the ...
