The breaker presents ceramic envelopes (1) , one for each terminal, having an inner chamber (2) filled with a dielectric gas. The chamber houses an arc contact (3), which is mobile along a longitudinal axis (4), and a fix contact (5). The envelope also houses a second semi-mobile arc contact (6) which cooperates with a second fixed contact (7). The fixed contact is attached to a cylinder (8) with lateral openings (9) for gas evacuation. The semi-mobile contact is actuated by a spring (16).
