Product Description

JN15A-12/31.5 12kV High Voltage Indoor Earthing Switch for Switchgear

The JN15A-12/31.5 Indoor High Voltage Earthing Switch is designed for safe grounding of 12kV AC circuits in indoor switchgear. This manual earthing switch does not include sensors, making it ideal for straightforward maintenance operations where automatic indication is not required.

Built to withstand short-circuit currents up to 31.5kA, the switch ensures reliable operation during grounding procedures. Its compact and modular design allows seamless integration into standard switchgear panels, while the robust mechanical construction guarantees long-term durability and low maintenance.

This earthing switch provides a simple, safe, and effective solution for operators to discharge residual currents, protecting both personnel and equipment during maintenance. It complies with relevant IEC/GB standards for insulation, mechanical strength, and operational safety.
