Abstract (en)

[origin: EP0433184A1] The circuit-breaker includes main contacts (26, 30) and a vacuum canister (38) in parallel which ensures disconnection, the whole being contained in an enclosure (10) filled with sulphur hexafluoride. The canister is designed for dielectric holding in this gas. The contacts of the canister (38) are of a refractory material and a coil generates an axial magnetic field in the region of the arc. <IMAGE>
