Abstract
Circuit interrupter having an arc extinguisher which functions to arrest an arc between its contacts regardless of the polarity of the contacts. The circuit interrupter includes one or more permanent magnets configured to drive an arc into the arc extinguisher. The arc extinguisher may include two arc paths, each including arc splitter plates. The two arc paths may be adjacent, each extending in a parallel direction. The arc paths may alternatively be non-adjacent, each extending in a perpendicular direction.
