ABSTRACT:
A vacuum interrupter includes an evacuated envelope and a pair of facing contacts situated therein. The contacts are relatively movable along a first axis from an engaged position to a disengaged position. Conductors extending through the envelope are provided for connecting the contacts to an external circuit. A pair of magnetic field coils are disposed on opposite sides of the contacts and connected in series therewith for establishing an axial magnetic field in the space between the contacts when the contacts are in the disengaged position.
