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.

Device for protecting a user

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.

Device and method for protecting a consumer

A triggering unit includes a tappet having a moving bearing, a power accumulator, a holding device and a printed circuit board coil. In the normal state the power accumulator acts upon the tappet with a power accumulator force in the direction of the first stop position and the holding device holds the tappet with a holding force in the second stop position. A printed circuit board coil force can be generated by an activation of the printed circuit board coil. The power accumulator, the holding device and the printed circuit board coil are formed such that the tappet rests in the second stop position in the inactive state of the printed circuit board coil and through an activation of the printed circuit board coil, the tappet assumes the first stop position such that the triggered status is given.

Triggering unit for actuating a mechanical switching unit of a device

A control module with connection devices for connection to connection terminals of a load feeder is disclosed. The control module may include a device interface for at least one connection, the interface being independent of the bus system, with a shut-off element able to be connected to the at least one connection device and with the load feeder able to be shut off by way of the shut-off element independently of the bus system. The control module may be plugged into connection terminals of the load feeder.
