ABSTRACT:
A vacuum-type circuit interrupter comprises two pluralities of rod electrodes positioned to form a ring of electrodes in which the electrodes of the first plurality interleave with those of the second plurality and are spaced circumferentially of the ring from the immediately adjacent electrodes of the second plurality. A first conductive tube mounts the electrodes of the first plurality on a first conductive end cap of the interrupter, and a second conductive tube mounts the electrodes of the second plurality on a second conductive end cap of the interrupter. First and second stationary contacts are respectively mounted on the distal ends of a rod electrode in said second plurality and a rod electrode in said first plurality. A first movable contact rod extends through said first end cap and through said first tube and carries a movable contact for engaging said first stationary contact. A second movable contact rod extends through said second end cap and through said second tube and carries a movable contact for engaging said second stationary contact. The two pairs of engageable contacts are electrically connected in parallel with each other when the interrupter is closed.
