Abstract: A gas-insulated type circuit breaker (1) comprises a housing (4) defining a gas volume for a dielectric insulation gas; a first arcing contact member (10) and a second arcing contact member (20), wherein the first arcing contact member (10) and the second arcing contact member (20) are movable relative to each other along an axis (2); a first nominal contact member (40) and a second nominal contact member (60), wherein the first nominal contact member (40) and the second nominal contact member (60) are movable relative to each other along the axis (2); and a first nominal contact shielding arrangement (50) comprising an inner shield member (52) and an outer shield member (54), wherein the inner shield member (52) and the outer shield member (54) are arranged coaxially about the axis (2). The first nominal contact member (40) is arranged co-axially between the inner shield member (52) and the outer shield member (54), and is movable relative to the inner shield member (52) and to the outer shield member (54).
