Abstract: An overvoltage protection element having at least one overvoltage limiting component in a housing, terminal contacts for electrical connection of the overvoltage protection element to a path to be protected, an electrically conductive connecting element and with a spring system acting on the connecting element, a first terminal contact being directly connected with the first pole of the overvoltage limiting component, the connecting element being in electrically conductive contact with the second terminal contact and the second pole of the overvoltage limiting component via a thermally separating connection. With the thermal connection separated, the connecting element moves out of electrically conductive contact with the second terminal contact and the second pole of the overvoltage limiting component by the force of the spring system an insulating disconnecting element connected to the connecting element is moved between the second terminal contact and the second pole of the overvoltage limiting component.

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.

Abstract: An overvoltage protection device for protection of low voltage electrical installations, has a device base part with terminals for phase conductors and ground or neutral conductors and at least one overvoltage protection element, with at least one arrester which is located in a housing. The base part of the device has at least one telecommunications contact which has a switch for remote indication of the state of at least one overvoltage protection element, the base part of the device having plug contacts which are connected to the terminals, and the overvoltage protection element having corresponding connector contacts so that the overvoltage protection element can be plugged onto the base part of the device. The overvoltage protection device is improved by the overvoltage protection element having an optical status display and the optical status display and the switch of the telecommunications contact being actuated via a common mechanical actuating system.
