GN19-12 series indoor high voltage isolation switch for the rated voltage 12KV, three-phase AC 50HZ indoor unit, as there is no voltage under load points, co-circuits. GN19-12/400, 630,1000,1250 isolating switch conductive parts per phase through two insulators fixed on the base. (GN19-12C/400A, 630,1000,1250 type, compared with an as insulators, one for the porcelain bushing insulators) three-phase parallel installation, the conductive part by touching knives, static contact, touch the seat (or conductive rod) composition . Touch the middle of each phase are connected with knife rod insulators, rod insulators with spindle mounted on the base is connected. Spindle through the handle with rod and CS6-1-type institutions linked together practicing hand linked.
