Abstract: The invention relates to a surge protection device with connection elements, an overvoltage protection device (ÜSE1), two contact elements (K1, K2), a slide (AS), a connection plate (B) and a force accumulator (F). The two contact elements (K1, K2) and the overvoltage protection device (ÜSE1) are encased with an electrically nonconducting material on the surface. The electrically nonconducting material leaves open a connection area (A) formed on the second contact element (K2). In a first state, the connection plate (B) is connected to the connection area (A). The slide (AS) is arranged such that it can slide on a surface of the electrically nonconducting material under the action of the force when the thermally softenable contact means softens in a second state, wherein the slide (AS) is displaced between the connection plate (B) and the connection area (A). The electrically nonconducting material is assigned a further function.

Abstract: The invention relates to an overvoltage protection device with varistors, wherein a first varistor and a second varistor are connected in series, wherein the first varistor has a thermal disconnector, wherein the first varistor has a lower operating voltage than the second varistor, and wherein the first varistor has a lower energy absorption capacity than the second varistor, with the first varistor heating up more in the event of an overload and thereby causing the thermal disconnector to disconnect.

Abstract: 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.
