Abstract

A device for protecting a user includes a first current path including a first and second conduit, and a monitoring device for detecting an imminent overload of the electric user. In an embodiment, the monitoring device includes a first temperature measurement unit, a support, an evaluation unit and a first transducer to produce an electrically conductive connection between the first and second conduits of the first current path. The first temperature measurement unit is, electrically insulated from the first transducer and includes a first temperature sensor. An additional electrically insulating material; is arranged on a first lateral surface of the support between the first transducer and the support and the first temperature sensor is arranged on the support to detect a temperature of the first transducer. The evaluating unit is configured to detect an imminent overload at the user on the basis of temperatures detected by the first temperature sensor.
