Abstract
A main valve for an arc chute is formed by a flexible sheet member that is mounted over a gas opening of the arc chamber structure by extensions on arc plates that form guides received in elongated slots in the ends of the flexible sheet member. The force generated by high pressure gas in the arc chamber on the center of the flexible sheet member causes it to bow allowing arc gases to escape laterally as the ends of the flexible sheet member are drawn towards each other. Flaps formed by slits in the flexible sheet member are deflected by lower pressure gas before the flexible sheet member bows outward.
