摘要:The invention relates to a protective circuit (1) for protection of an appliance, inparticular of an electric motor, against thermal overloading, comprising a first and asecond terminal (2, 3) for connecting a temperature detection element (4, 11); adetection unit (6) for detecting whether a resistance value of the temperature detectorelement (4, 11), which is connected between the first and the second terminals (2, 3), is ina first or a second resistance range; a short-circuit detector for identifying whether thereis a short circuit between the first and the second terminals (2, 3); signalling outputs (8, 9)for emitting signal messages to an evaluation unit (14) when the detected resistancevalue is in the second resistance range and/or when a short circuit has been identified bythe short-circuit detector (10); and a third terminal (12), which is connected to the secondterminal via a predetermined resistance.
