Abstract

A device for switching a direct current in a pole of a direct current network includes two connecting terminals to be connected in series with the pole, an operating current path extending between the connecting terminals, at least one mechanical switch in the operating current path, a disconnection branch including a power switching unit for shutting down high short-circuit currents having power semiconductor switches that can be switched on and off, and a commutation device for commutating a current from the operating current path to the disconnection branch. In order to provide such a device which is economical, generates fewer losses and at the same time is able to switch high short-circuit currents quickly, the commutation device is provided with at least one inductive component.
