Abstract
PURPOSE:To enhance interruption performance, voltage resistance characteristic and durability by making optimum a relationship between a gap from a metal shield to the peripheral side of an arc part, and the thickness of the peripheral part of the arc part. CONSTITUTION:The arc part 10 of a rotary type electrode pair 9 driven on arc magnetism is formed with a complex metal material containing copper and metal of a higher melting point than copper and hard quality, and provided in place. And a gap l between a metal shield 3 surrounding the electrode pair 9 and the peripheral side of the arc part 10 is so related to the thickness B of the peripheral part of the arc part 10 as to be B>=l. According to the aforesaid construction, the density of arc energy can be reduced. Also, it is possible to enhance interruption performance, voltage resistance characteristic and durability.
