Abstract

A device for obtaining breaking of the current in a current path (2) for an alternating current with a plurality of phases and a dc-component of at least one phase current, i.e. displacement of the symmetry line of the phase current with respect to the zero-level thereof, through opening of an electric switching device (1) arranged in a part current path for each phase and thereby breaking the current in the current path after occurrence of a fault current in the current path, comprises members (15) adapted to detect the current in the part current path of each phase and a unit (19) adapted to control the electric switching devices to break the current in the respective part current path at a point of time being dependent upon the result of the current detection.
