To provide an electric circuit breaker device that can quickly extinguish an arc generated during actuation.SOLUTION: An electric circuit breaker device includes: an igniter that is provided in a housing; a projectile that is arranged in a cylindrical space formed in the housing, and is formed movable in the cylindrical space by energy received from the igniter; a conductor piece that is provided in the housing and forms a part of an electric circuit, has in a part thereof a cutoff portion to be cut off by the projectile, and is arranged with the cutoff portion crossing the cylindrical space; and a fibrous coolant material that is arranged in an arc-extinguishing region that is positioned in the cylindrical space, on a side opposite to the projectile prior to actuation of the igniter with the cutoff portion interposed between, and is to receive the cutoff portion cut off by the projectile.SELECTED DRAWING: Figure 2

    【課題】作動時に発生したアークを迅速に消弧することの可能な電気回路遮断装置を提供する。【解決手段】ハウジングに設けられた点火器と、ハウジング内に形成された筒状空間に配置された発射体であって、点火器から受けるエネルギーにより筒状空間を移動可能に形成された発射体と、ハウジングに設けられると共に電気回路の一部を形成する導体片であって、その一部に発射体によって切除される被切除部を有し、当該被切除部が筒状空間を横切るように配置された導体片と、筒状空間のうち、点火器の作動前において被切除部を挟んで発射体とは反対側に位置し、発射体によって切除された被切除部を受けるための消弧領域と、消弧領域に配置された、繊維状のクーラント材と、を備える。【選択図】図2
