Abstract: An overvoltage protection element with a housing, an overvoltage-limiting component arranged in the housing, and with two connection elements for electrically connecting the overvoltage protection element to the current or signal path to be protected, wherein, normally, the connection elements are each in electrical contact with a pole of the overvoltage-limiting component. Reliable and effective electrical connection in the normal state and reliable isolation of a defective overvoltage-limiting component are ensured by the fact that a thermally expandable material is arranged within the housing in a way that, in the event of thermal overloading of the overvoltage-limiting component, the position of the overvoltage-limiting component is changed by expansion of the thermally expandable material relative to the position of the connection elements in a way that causes at least one pole of the overvoltage-limiting component to be out of electrical contact with the corresponding connection element.

Abstract: The subject matter of the invention is a device for diverting surge currents or transient overvoltages (1), with a switching stage (2) and a switching element (3). The switching stage (2) is so designed as to switch on the switching element (3) upon identification of an overvoltage or a surge current. The switching element (3) is a reversible semiconductor switching element, while the switch-on event is achieved by operating of the switching element (3) outside of the specified parameters.
