Arc 11 generated after opening of both contacts 2, 3 is extended in an arc generating chamber 9 while it is driven at a high speed by a Lorentz's force in the circumferential direction, so SF6 gas, for example, filled in the chamber 9 is heated effectively to let through a communication part 10 to flow into a heat accumulation chamber 8 for accumulating a pressure. A gas blow force to the arc 11 is thus increased close to a current zero point, and a relative gas flow speed between the gas and the arc is increased as a rotation speed of the arc 11 is increased. Even when a breaking current is small, therefore, arc-extinguishing characteristics are not deteriorated.
