DEVICE AND METHOD FOR PROTECTING A CONSUMER

摘要

A device is disclosed for protecting a consumer, with a first current path having two lines, and a monitoring arrangement for detecting an imminent overload of the electrical consumer. In order to enable the detection of an imminent overload of a consumer, it is proposed that the monitoring arrangement includes a first temperature measuring unit, an evaluation unit and a first measuring element, which establishes an electrically conductive connection between the two lines of the first current path. The first temperature measuring unit is electrically isolated from the first measuring element and includes a first and a second temperature sensor. The first and second temperature sensor of the first temperature measuring unit are configured to simultaneously record a temperature of the first measuring element and the evaluation unit is configured to detect an imminent overload of the consumer based upon the recorded temperatures of the first temperature measuring unit.
