摘要： A surge suppressor with a housing, a varistor located in the housing, an electrically conductive connecting element and at least one isolating interrupter. The isolating interrupter is movable relative to a first terminal of the varistor out of a first position into a second position, in the normal state of the surge suppressor, a first end of the electrically conductive connecting element being connected to the first terminal of the varistor in an electrically conductive manner and the isolating interrupter being held in its first position. When a critical state of the varistor is reached, the isolating interrupter is moved into its second position in which a segment of the interrupter is located between the first end of the electrically conductive connecting element and the first terminal. Reliable disconnection from the power system is ensured by the arc formed being moved into at least one partially closed chamber.

摘要： The invention relates to a separating device for an overvoltage protection element, wherein the separating device is to be arranged between the overvoltage protection element and a thermal disconnector, wherein the separating device has a first insulating layer and a second insulating layer, wherein a conductive layer is arranged between the first insulating layer and the second insulating layer, wherein the first insulating layer has a first cutout for a contact with the disconnector, and wherein the second insulating layer has a second cutout for a contact with the overvoltage protection element, wherein the cutouts provide a possibility for contacting the conductive layer and the conductive layer provides a thermal bridge between the overvoltage protection element and the thermal disconnector, with the insulating layers making both a thermal and an electrical insulation available, so that heat of the overvoltage protection element can be conducted in a focused manner to the thermal disconnector.
