The invention relates to an apparatus (1) for protecting a consumer (2) from overload. In order to provide an improved apparatus (1) which has an optimized design in particular as regards its thermal loading, what is proposed is: a monitoring device of the apparatus (1) which has a temperature measurement unit (18), an evaluation unit (4) and an instrument transducer (10), which electrically conductively connects the first line (101) to the second line (102), wherein the temperature measurement unit (18) can detect a temperature of the instrument transducer (10), wherein the evaluation unit (4) can determine a temporal heating response of the instrument transducer (10) by means of the detected temperatures of the temperature measurement unit (18) and can determine a pending overload at the consumer (2) by means of an evaluation of the determined temporal heating response of the instrument transducer (10), wherein, at the mechanical and electrical connection point between the instrument transducer (10) and the first and/or second line (101, 102), the instrument transducer (10) has a coating (5), - the instrument transducer (10) or the first and/or second line is flattened or - in each case one platelet (6) is arranged between the instrument transducer (10) and the first and/or second line (101,102). |
