Abstract
A contact construction is disclosed for a circuit interrupter of the type in which an arc drawn between cooperating arcing contacts is caused to circulate around an axis and through a dielectric gas in order to extinguish the arc. The movable contact is so constructed that the current path is directed radially relative to the contact axis so that a magnetic force is applied radially inward to the arc which roots on the movable contact. This magnetic force tends to move the arc root on the movable contact to the innermost radial position on the movable contact. The arc is also forced in a direction away from exteriorly positioned main contact components.
