A surge protector includes a thermal separating device and an error display, and at least two first protection elements, particularly disk-shaped varistors (), and at least one second protection element, particularly a gas arrester (), wherein the first and the at least one second protection elements are switched in a Y arrangement. The surge protector further includes a device housing for accommodating the protection elements, and structure, such as a spring (), for the mechanical biasing of the thermal separating device, wherein the thermal separating device has a low-melting solder, and the first protection elements () are disposed in the device housing such that a connection arm of a protection element () is positioned opposite the connection arm of the further protection element () at a distance, and the thermal separating device is predominantly positioned in the distance space () formed in such a manner.

Surge protector having a thermal separating device

The invention relates to a plug-in combination of appliances for protecting against overvoltages, said combination of appliances comprising: a socket-type lower part and at least one plug-in module, which can both receive overvoltage protection elements; contact elements and contact counter elements that are respectively arranged in the lower part and in the plug-in module; and complementary guide rails or guide grooves for inserting or pushing-on and fixing the respective plug-in module. According to the invention, functionally separated, mechanical catch or snap-in elements act between the respective plug-in module and the socket-type lower part independently of the forces which hold together the contact elements and the contact counter elements in a positively fixed and/or non-positively fixed manner when the plug-in module is in use. The catch or snap-in function can be cancelled without any mechanical auxiliary means when the respective plug-in module is to be replaced.
