ABSTRACT OF THE DISCLOSURE: A vacuum interrupter of improved large current interrupting capability and dielectric strength. The interrupter has a pair of separable electrodes, a vacuum envelope electrically insulating and enclosing the pair therewithin, a contact-making portion of material of 20 to 60% IACS electrical conductivity being a part of one electrode of the pair, a magnetically arc-rotation portion of material of 2 to 30% IACS electrical conductivity secured to the contact-making portion so as to be apart from the other electrode when the electrodes are in engagement. Means, which include a plurality of slots extending radially and circumferentially of the magnetically arc-rotating portion and being apart from each other, are provided for magneti- cally rotating the arc established between the electrodes on an arcing surface of the electrode.
