Abstract

Each outermost part of fixed-side connection conductors, fixed-side fixed contacts, movable-side fixed contacts, and movable-side connection conductors are placed outside of an outermost diameter of a fixed-side conductor and a movable-side conductor, as viewed from an axis line of the fixed-side conductor and the movable-side conductor as a center. This arrangement provides a power switchgear that can diminish mutual effects of currents among conduction parts to suppress decrease in a current-carrying capacity for each of the conduction parts and to increase a current-carrying capacity for a total of the conduction parts, without increasing the size of the switchgear.
