FIELD: electrical engineering, in particular, air-blast SF6 circuit breakers. SUBSTANCE: device has arc-quenching unit, which has pair of ON contacts. Mobile contact is connected to end wall and serves as part of mobile contact unit. In addition device has cap which provides dynamic pair of chamber-plunger type together with end wall, side wall which is located around mobile contact, and mobile contact. EFFECT: increased efficiency of arc-quenching, increased electric strength of contact gap. 1 dwg øøø1
