Claim:
1. A device for connecting to a power network, comprising: a circuit board; a first input-side connection point, to which a first phase of the power network is connectable, a second input-side connection point, to which a second phase of the power network is connectable; and a first and a second electrical conductor, the first conductor being connected to the first input-side connection point and the second conductor being connected to the second input-side connection point inside the device, the first conductor further being routed as a conductor trace in an interior layer of the circuit board and including a constriction, and the second conductor being 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 via the first conductor, to provide an electrically conductive connection between the first and second conductor.
