Abstract
Electric circuit breaker device that can be downsized by reducing the distance the moving body moves, including a housing; a cut part placed inside the housing; and a power source placed on the housing, further including a moving body having a first arc-extinguishing space into which the cut part is inserted and housed, and which is filled with an arc-extinguishing material, and a moving body housing part that allows the moving body to move between the first end part and a second end part opposite to the first end part, which is configured to cut the cut part while moving toward the power source P, and the housing includes an expanded arc-extinguishing space positioned so as to face an end part of a separable piece of the cut part when the moving body has moved and stopped, and the expanded arc-extinguishing space being filled with an arc-extinguishing material.
