The present invention relates to an apparatus for short circuit protection. The apparatus comprises two supply inputs for connecting the apparatus to a terminal of a power supply and two supply paths being connected together and to the supply inputs, wherein each supply path comprises a disconnection means for disconnecting the supply path. Further the apparatus comprises a determination means for determining a current flowing from one of the supply paths through the other one of the supply paths and a control means for controlling the disconnection means of the supply paths dependent on the current determined by the determination means, wherein the control means is connected with the disconnection means and the determination means.
