An improved circuit-interrupter is provided having a high-frequency transverse magnetic field to assist in the very rapid interruption of the arc, which is established during operation of the device, said magnetic field being preferably of the three-phase type and rotating, having three separate field coils energized by a transitory, high-frequency power source to result in an interaction between the arc column and the transversely-oriented, high-frequency, multi-phase magnetic field of transitory duration to thereby afford a more intimate interaction with the arc-extinguishing medium, which may be gaseous, for example.
