The release device is formed by a pressure spring, a metal spring sheet, a sliding A block, and a soft conductor. The arc-control device is 2 formed by an arc-control grid sheet group, a first arc strik ing sheet, a second arc striking sheet, a rotation block, and a torsional spring. The rotation block is a strip-shaped block, an electric arc reflecting plate is arranged on one end por tion of the rotation block, an installation hole is formed in 7 the other end portion of the rotation block, and an arc-con trol cavity is formed in the position, close to the electric arc a reflecting plate, of the rotation block. The arc-control grid sheet group is installed in an arc-control chamber surroun ded by the box body and the shell. One end of the first arc striking sheet is connected to or close to a left end of the 4 /FG.arc-control grid sheet group, and one end of the second arc M 1 FIG.4 striking sheet is connected to or close to a right end of the arc-control grid sheet group.
