Overview

The GN30-12 type rotary indoor high-voltage disconnect switch is a new type of rotary contact knife disconnect switch. Its main structure consists of two sets of insulators and contacts fixed on the upper and lower planes of a three-phase common base frame. The opening and closing of the switch is achieved by rotating the contact knife.

The GN30-12D type switch is based on the GN30-12 type switch with the addition of a grounding switch, which can meet the needs of different power systems. This product features a compact design, small footprint, strong insulation, and easy installation and adjustment. Its performance meets the requirements of GB1985-89 "AC High Voltage Disconnecting Switches and Grounding Switches," and is suitable for indoor systems with a rated voltage of 10 kV AC 50Hz and below, used for switching circuits when there is voltage but no load. It can be used in conjunction with high-voltage switchgear or independently.
