Abstract
An object is to provide a vacuum circuit breaker that has a lower electrical and thermal resistance at contacting portions between a movable electrode-rod and a movable-electrode-side connection-terminal so that a continuous current-carrying capacity is made larger without reinforcement and/or enhancement of an operating mechanism. The vacuum circuit breaker herein provided includes a vacuum interrupter held inside an insulation frame; a fixed electrode-rod mounted on one side of the vacuum interrupter; a movable electrode-rod mounted on the other side of the vacuum interrupter; a flexible conductor for electrically connecting the movable electrode-rod with a main-circuit conductor; and a movable-electrode-side connection-terminal fastened on the outer circumference of said movable electrode-rod; wherein the flexible conductor is gripped by a first face and a second face of the movable-electrode-side connection-terminal.
