Abstract:
An overvoltage protection element with a housing, at least one overvoltage limiting component in the housing, especially a varistor, and two connecting elements for electrically connecting the overvoltage protection element to a current or signal path in a normal state, the connecting elements being in electrically conductive contact with a respective pole of the overvoltage limiting component. In the normal state of the overvoltage protection element, at least one pole is connected to a connecting element via a plug-and-socket connection, and at least one spring is located between the housing and the overvoltage limiting component such that, when the overvoltage limiting component is thermally overloaded, it is turned by the spring separating the at least one pole from the assigned connecting element, and creating a thermally separating connection between the overvoltage limiting component and the housing when the temperature of the overvoltage limiting component exceeds a given boundary temperature.
