Abstract

A compressed gas type circuit breaker device that includes a cooperating moving contact with a stationary contact, from which it can be separated, at least one of the contacts being tubular and having a high pressure zone formed in the region of contact with a primary blow-off valve that regulates gas circulation through the tubular contact when in the closed-loop position, at least one secondary blow-off valve pneumatically connected to the region inside the tubular contact to control evacuation flow of gas through the tubular contact in the open circuit position and means for blocking the secondary blow valve in the open position.
