Abstract (en)

[origin: EP0749139A1] The circuit breaker (10) includes a protective insulating envelope (12) filled with a dielectric gas and housing a pair of cross rails (14,16) directly connected to an isolating switch (18) of the main circuit (19). The switch includes an envelope (17) housing a fix contact (20) attached to the first rail (14) with screws 21). A mobile contact (22) rotates about an axis (24) in a support (26) attached to the second rail (16). The breaker envelope includes an auxiliary circuit with a cut-off chamber (34) which houses a pair of arc contacts (36,38). One of the arc contacts is mobile and can slide longitudinally between open and close positions. The arc contacts are connected in parallel with the two rails via a conductor (40).
