Abstract: A network monitoring device for a supply network and a method for actuating a switch unit are disclosed, wherein the switch unit can control the energy supply of a consumer connected to a supply network. In order to prevent an overload of the supply network or of parts thereof, according to an embodiment of the invention, the network monitoring device includes a communication device, wherein the network monitoring device can receive a switch command for a switch unit via the communication device and transmit same to the switch unit, wherein the network monitoring device is designed to determine a network utilization of the supply network by way of a measurement device and, in dependence on the determined network utilization,; to influence a received switch command for the switch unit, which would lead to increased energy consumption on the supply network.

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.
