Remotely controllable circuit breaker with improved arc drive structure

摘要: A remotely controllable circuit breaker has an improved scheme for effecting rapid arc extinction as well protecting the contact from resulting current. The includes first and second movable contacts 11 12 which are held respectively on parallel extending arms 31 32 driven individually by a switching mechanism 20 including manual handle 22 with trip capability switch 60. An runner 115 is connected to be in same electrical potential arm extends separating direction receiving one end of developed between rapidly guiding toward extinguishing chute 110 moves away 12. at its opposite drive member 116 immediately behind relation thereto. repulsion force acts urge extinction. At this time, current will bypass it overcurrent.
