Abstract

An overvoltage protection element with a housing, with at least one overvoltage limiting component which is located in the housing, especially a varistor, with two terminal lugs which are each connected to a respective pole of the overvoltage limiting component in an electrically conductive manner, especially soldered or welded, and with two connecting elements for electrical connection of the overvoltage protection element to the current path or signal path to be protected. In the normal state of the overvoltage protection element, the connecting elements are each in electrically conductive contact with a respective terminal lug. The overvoltage protection element can be produced especially easily and economically by the first terminal lug and the first connecting element being integrally connected to one another and by the free end of the first connecting element which faces away from the overvoltage limiting component being made as a plug-in contact.
