  • Contact for a medium-voltage vacuum circuit-breaker with improved arc extinction, and an associated circuit-breaker or vacuum circuit-breaker, such as an AC generator disconnector circuit-breaker
    Patent number: 8164019
    Abstract: A vacuum circuit-breaker wherein one contact body is made with two windings implanted concentric with one another and connected electrically in parallel. The second winding is in the form of an solid part with an annular ring. The circuit-breaker increases the axial magnetic field (AMF) and distributes it uniformly over the contact surface so that arc extinction is improved for high short-circuit currents, typically greater than 63 kA.
