摘要：At least one embodiment of the invention relates to a protective circuit for
protection of an appliance, in particular of an electric motor, against thermal overloading.In at least one embodiment, the protective circuit includes a first and a second terminalfor connecting a temperature detection element; a detection unit for detecting whethera resistance value of the temperature detector element which is connected between thefirst and the second terminals, is in a first or a second resistance range; a short-circuitdetector for identifying whether there is a short circuit between the first and the secondterminals; signaling outputs for emitting signal messages to an evaluation unit when thedetected resistance value is in the second resistance range and/or when a short circuithas been identified by the short-circuit detector; and a third terminal, which is connectedto the second terminal via a predetermined resistance.
