Abstract (en)
A configuration such that there is an advantage in increasing external force working on an arc, and a shortening of commutation time is realized, is obtained with a simple configuration, and without an increase in size of a device. An arc generating chamber configured of main contactors provided on a fixed side and a movable side, arc contactors provided on the fixed side and the movable side, and a side wall of an arc extinguishing chamber, is such that at least a side face and a bottom face are enclosed by an insulating wall, leaving an opening in a direction facing the arc extinguishing chamber.
