Abstract

A device for connecting to a power network includes a circuit board, a first input-side connection point, to which a first phase of the power network can be connected, a second input-side connection point, to which a second phase of the power network can be connected, and a first and second electrical conductor. The first conductor is connected to the first input-side connection point and the second conductor is connected to the second input-side connection point inside the device. The first conductor is routed as a conductor trace in an interior layer of the circuit board and includes a constriction. The second conductor is routed past the constriction such that electrical insulation existing between the constriction of the first conductor and the second conductor is destroyed in the case of a short-circuit current, to provide an electrically conductive connection between the first and second conductor exists.
