Introduction
The GN19-12 indoor disconnector is of three-phase compact structure, having reliable performance and wide applicability. The blade is of vertical rotary type and gantry shape, which not only improves mechanical strength, but also increases heat dissipation area. The static contact is cast into a monoblock which features high mechanical strength, and it comes in a platy shape which shortens blade clearance and greatly improves electrical stability.

This indoor high voltage disconnect switch can be equipped with CS6-1 hand actuator or JSXGN2 mechanical locker. As a type of electrical component, it is mainly mounted in GG-1A, XGN2-1 2 medium voltage switchgear. GN19-12 disconnector is of horizontally mounted type, while GN19-12C disconnector is of wall bushing type.
