Claim:
1. A circuit interrupter including arc suppression comprising: a first contact electrically connectable to a power source; a second contact electrically connectable to a load; said first and second contacts being movable between a closed and open position relative to each other; an arc extinguisher for extinguishing an arc that develops in the vicinity of said first and second contacts; a permanent magnet disposed in the vicinity of at least one of the contacts, said permanent magnet having a first end having a first magnetic polarity and a second end having a second magnetic polarity opposite to the first magnetic polarity, said permanent magnet generating a magnetic field; a first pole piece comprising a magnetically permeable material; a second pole piece comprising a magnetically permeable material, said second pole piece positioned apart from and substantially parallel with said first pole piece to form a gap where said first and second contacts are positioned; said first pole piece positioned adjacent to the first end having the first magnetic polarity and said second pole piece positioned adjacent to the second end having the second magnetic polarity; a non-magnetic pole structure having: wherein the magnetic field extends across a gap formed between the first and second pole pieces such that an arc that forms in the gap is drawn in a direction toward said arc extinguisher.
