Abstract (en)
[origin: JPH05198235A] PURPOSE: To provide a circuit breaker which is equipped with a contact arc contactor and usable for middle voltage or high voltage by and solves a problem of repulsion of contact contactors without increasing contracting stress of a spring. CONSTITUTION: A circuit breaker provided with a contact arc contactor for middle voltage and high voltage is provided and the breaker comprises a movable apparatus constituted of a first fixed contactor 8, a first tube 2 moved by a driving rod, and a semi-movable second tubular contact contactor 9 which are installed in a casing filled with a gas having excellent dielectric properties. The circular end part 2A of the first tube 2 carries a contact arm ring 20. The contact arm ring smoothly slides on the first contact contactor 8 and is provided with an arc contactor block 21 at the end part. A contactor projected part 22 is constantly installed near the block.
