Abstract The invention is an excess temperature protection element for photovoltaic installations. The element has a cylindrical housing closed off with two cover plates, encasing therein a plug-and-socket connection that is certified for photovoltaic installations. The plug connector is connected to the interior face of one cover plate and the socket connector to the interior face of the second cover plate, so that the two connectors are in electrical contact with each other when the housing is closed. A pressure element between the two cover plates biases the plates away from the housing. One of the plates is a releasable plate secured to the housing by a hot-melt material. When the temperature of the PV installation rises above a threshold value, the hot-melt material softens, allowing the pressure element to push the releasable cover plate away from the housing, thereby disconnecting the plug-in connection in the housing.
