PROBLEM TO BE SOLVED: To improve a structure and an arrangement of a disconnector so as to improve assembling property and reduce a space in a discharging disconnector of a commutating capacitor mounted on the back face side of a cradle equipped with a drawing circuit breaker in a DC breaker for blocking by using the commutating capacitor. SOLUTION: In the DC breaker provided with a plurality of discharging circuit breakers 4 in parallel for connecting the capacitor to a discharging circuit behind the cradle 1 equipped with the drawing circuit breaker as a means for discharging a charge stored in the commutating capacitor to the ground through a discharging resistor, all the discharging circuit breakers 4 are vertically turned off and aligned horizontally and vertically oriented, fixed contacts 4a are provided on the upper back face side of the cradle in parallel, opening and closing levers 4b are coupled on a lateral common rotational shaft 9 at an lower end, an operation handle is linked to the rotational shaft, and the disconnectors are collectively opened and closed.
