Abstract
PURPOSE:To facilitate the cutoff of the high voltage by providing an intermediate electrode covering the tip of a movable electrode and a notch when a contact is opened on an arc extinguishing plate. CONSTITUTION:An intermediate electrode 10 provided on the uppermost arc extinguishing plate 6 is formed by cutting and erecting the notch section of the arc extinguishing plate 6, for example. The intermediate electrode 10 is covered over an arc horn 9 and arranged at least to satisfy x>=0, where (x) is the distance between the tip of the arc horn 9 and the tip of the intermediate electrode 10. Since an arc 11 is quickly separated from the vicinity of a movable contact 4 during a large current, the insulation recovery after the current zero point of the space between contacts 3, 4 with the shortest insulation distance is accelerated, and the arc voltage at the current zero point is increased. The cutoff of the high voltage is thereby facilitated.
