The gas pressure which is generated from high-polymer materials is accumulated in the accumulating space, and the gas is blown to the arc to extinguish. Especially this technology improves the high voltage breaking performance. Unit case movable conductor egas flow rc blation gas jet through the hole installed on the unit case directly activates the trip mechanism. This acts faster than the relay (magnet), and contributes to improved current-limiting performance and breaking reliability. Trip Bar Tripping actuator to push the trip-bar before the trip by relay unit. Tripping ctuator Unit Case When short circuit fault occurs, the contacts are opened and arc is generated between the contacts. t that time the pressure in the unit case become very high. Extinguishing unit wccumulating space qblation Fixed conductor rc Extinguishing Concept VJC insulation (high polymer materials) qblation => wgas accumulating => egas flow => rc extinguishing Hole High pressure gas blows through the hole to rotate the tripping actuator 4

Optimization of the current path and the added magnetic core enhance driving electromagnetic forces. By the high-speed opening and the arc driving, the rising rate of arc voltage is increased and the peak current Ip is decreased. *The triple forces which are the repulsive force, the attractive force, and the pressure accelerate the separating speed of the movable conductor.
