Abstract
For a low-voltage protective device, comprising: at least a first outer conductor path with a bypass switch, a first semiconductor circuit arrangement connected in parallel to the mechanical bypass switch, the first semiconductor circuit arrangement comprising at least one power semiconductor, at least a first voltage-dependent resistor is arranged in parallel with the bypass switch and the first semiconductor circuit arrangement, a control and driver unit configured to drive the first semiconductor circuit arrangement with a control voltage, it is suggested, that the low-voltage protective device comprises a voltage-detection-arrangement for detecting a voltage drop at the first voltage-dependent resistor and/or at least one temperature-detection-device to measure the temperature of the first voltage-dependent resistor at least before a switch on of the low-voltage protective device.
