Description
The device is built on the SHD disconnector, and the disconnector blade operates the vacuum interrupter. Its bistable drive makes and breaks load currents. The arc is extinguished in vacuum. The SHD has a vertical break and its blade moves in the plane of the insulators, so the phase-to-phase distance is minimal.
