  • Multipolar circuit breaker
    Patent number: 6509817
    Abstract: A multipolar circuit breaker of great breaking capacity prevents arc gas from blowing out from the side at the time of cutting off a short-circuit current. A stationary contact and a movable contact generating arcs when a short-circuit current is cut off, and an arc extinguisher extinguishing the arc are stored in an arc extinguisher casing. By forming the ceiling, the bottom and the sidewalls connecting the ceiling and the bottom of the arc extinguisher casing in continuity so that no gap is formed by an outward internal pressure, blow out of arc gas from the sidewall portion is suppressed.
    Type: Grant
    Filed: October 30, 2001
    Date of Patent: January 21, 2003
