In a current limiter with electric valves for limiting a short circuit in an electric power supply, wherein two throttles are connected in series and in a parallel path with two series-connected valves, which are disposed in opposition to each other and the two parallel paths are interconnected by a connection extending between the common potential point of the valves and that of the throttles, the valves are semi-controlled valves, which, for the operation of the current limiter, are activated by an external control whereby the valves are converted from a conductive to a blocking state in which they remain so that the current limiter automatically limits the current upon the occurrence of a fault current exceeding a predetermined current threshold.
