12kV Rotary Isolator Switch GN30

The GN30-12D is a rotary indoor high-voltage isolating switch that integrates a main isolating switch and a grounding switch. It utilizes a vertical rotary closing mechanism—distinct from the traditional linear blade design of the GN19 series—resulting in a compact structure that minimizes cabinet space requirements and suits the latest generation of compact high-voltage switchgear. The main blade and grounding blade feature a mechanical interlock, enabling integrated operation for main circuit isolation and grounding; the opening action creates a clearly visible break, while the grounding blade ensures reliable grounding protection, meeting safety interlocking requirements for equipment maintenance. It serves as a mainstream integrated isolation and grounding component for 10kV complete switchgear units.
