Title: DEVICE FOR PROTECTING A USER
Abstract:
The invention relates to a device (1) for protecting a user (2), the device (1) having a first current path (100) which comprises a first and a second conduit (101, 102), and a monitoring device for detecting an imminent overload of the electric user (2). In order to provide a thermally and electrically optimised, improved and cost-effective device (1) by means of which an imminent overload of a user can be detected, the monitoring device comprises a first temperature measurement unit (18), a support (15), an evaluation unit (4) and a first transducer (10) that produces an electrically conductive connection between the first and second conduits (101, 102) of the first current path (100), the first temperature measurement unit (18) being electrically insulated from the first transducer (10) and comprising a first temperature sensor (11), an additional electrically insulating material (14) being arranged on a first lateral surface (151) of the support (15) between the first transducer (10) and the support (15) and the first temperature sensor (11) being arranged on the support (15) in such a manner that it can detect a temperature of the first transducer (10), the evaluating unit (4) being able to detect an imminent overload at the user (2) on the basis of temperatures detected by the first temperature sensor (11).
