Electrical Circuit Breaker Device

Abstract

The present invention provides an electric circuit breaker device that can suppress an increase in power of a power source and easily break an electric circuit even when resistance of a cut portion is reduced. An electric circuit breaker device includes a broken portion constituting a part of an electric circuit, in which the broken portion includes base pieces on both sides and a separation piece connected between the base pieces, and the electric circuit breaker device includes a pressing connection portion that connects, while pressing, contact surfaces of the base piece and the separation piece, and is configured such that the separation piece is moved by a power mechanism while being in contact along a contact surface with the base piece and is separated from the base piece, and thus connection between the base pieces is broken.
