Abstract: An embodiment of the invention relates to a device for protecting a load, with a first current path having two lines, and a monitoring arrangement for detecting an imminent overload of the electrical load. In order to enable the detection of an imminent overload on a load, it is proposed that the monitoring arrangement includes a first temperature measuring unit, an evaluation unit and a first transducer, which establishes an electrically conductive connection between the two lines of the first current path, wherein the first temperature measuring unit is electrically isolated from the first transducer and can record a temperature of the first transducer, wherein the evaluation unit can determine, using recorded temperatures of the first transducer, a temporary heating behaviour of the first transducer, and can determine, by evaluating the determined temporary heating behaviour of the first transducer, an imminent overload on the load.

Abstract: The invention relates to a measured value acquisition and processing unit (5) that facilitates the acquisition and processing of very small measuring signals in the range of interfering signals, such as, for example, noise, spillovers, etc. This means that the useful values to be detected usually contain interfering portions. The inventive measured value acquisition and processing unit (5) separately acquires these interfering portions by means of a switch element (10) disposed in the area of feed of the measured signals by means of which the measuring circuit is short-circuited in such a manner that the measured signal is not coupled in but only interfering signals that might occur in the measuring circuit are detected. The inventive method provides a large range of dynamic ratio for the detection of measured values at low costs.
