    • 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.
    • 公开了一种用于保护消费者的装置,其中具有两条线路的第一电流路径以及用于检测电消费者即将发生的过载的监视装置。 为了能够检测到消费者即将发生的过载,建议监视装置包括第一温度测量单元,评估单元和第一测量元件,该第一测量单元,第一测量单元在第一和第二测量单元的两条线之间建立导电连接 当前路径。 第一温度测量单元与第一测量元件电隔离并且包括第一和第二温度传感器。 第一温度测量单元的第一温度传感器和第二温度传感器被配置为同时记录第一测量元件的温度,并且评估单元被配置为基于第一温度测量单元的记录温度来检测消费者即将发生的过载。
