I. overview

GN24-12D (|,), GN24-12D (|,) C series indoor high voltage disconnectors are rated voltage 10kV, three-phase AC 50Hz indoor devices.

Structural form:

A, GN24-12D (1.2, 1.2) Q disconnectors are grounded at the dynamic (or static) contact side; the main knife and grounding knife are combined in an integral framework; type 1 is operated on the left side; type 2 is operated on the right side; type Q is a full-duty product and can be equipped with an electrified display device according to user's order requirements.

Type b, GN24-12SD |, (C1.2.3) disconnectors are movable and static contacts are grounded on both sides, and movable (or static) contacts can be replaced by wall-piercing bushing; (or both sides are replaced by wall-piercing bushing) the main cutter and two groups of grounding cutters are combined on the same frame, and one group of grounding cutters can be operated independently or simultaneously by a mechanism.
