Abstract

A device () for discharging an electrical overvoltage includes an overvoltage discharge unit () having a non-linear current/voltage characteristic at least in sections. A first terminal electrode () of the overvoltage discharge unit () is connected to a high-voltage terminal () of the device (). A second terminal electrode () of the overvoltage discharge unit () is connected to a low-voltage or ground terminal () of the device (). The overvoltage discharge unit () is surrounded, at least in sections, by an insulating body (). A cutting element () is connected to the low-voltage or ground terminal () and is disposed close to a high-voltage section of the overvoltage discharge unit (). The cutting element cuts into the insulating body () when the insulating body () distends as a result of an electrical overload, enabling an are to be sparked and stabilized between the high-voltage section and the cutting element ().
