ABSTRACT OF THE DISCLOSURE A fault current limiter in which a resistor is inserted by a running arc. The arc is allowed to burn in a commutating unit until the current zero-crossing. Upon the passage through zero the arc is extinguished and the current is commutated to a shunt resistor. The commutating unit comprises a gap-formed nozzle, in which the arc is burning. The nozzle is defined by two nozzle halves of a material which gives off gas under the influence of the arc. Close to the nozzle inlet is a pressure accumulating chamber, in which an overpressure is built up during the arcing time. After current zero-crossing, the hot arc residues are effectively vented by means of the overpressure in the pressure accumulating chamber. For cooling the gas in the chamber and for guiding the gas flow, the chamber is divided into small sub-volumes defined by metal plates.
