したことを特徴とする回路しゃ断器。In a circuit breaker having at least one pair of electrical contacts that are constituted by a conductor and a contact fixed thereto and that open and close within an insulating container, the fixed end of the electrical contact has its central axis aligned with the fixed end of the electrical contact. The contact is configured to be perpendicular to the surface of the contact, and the cross-sectional area of the fixed end of the contact is set to be approximately the same as the surface area of the contact, and a pressure storage chamber is formed near the load side in the container. A circuit breaker characterized in that the container has a sealed structure except for the arc discharge port on the side wall on the power supply side.
