12kV Rotary Indoor Disconnector GN30-12D
The GN30-12 indoor high-voltage isolating switch is a rotary-type isolation device rated for 12kV, specifically designed for KYN28-series metal-clad switchgear. It performs opening and closing operations through the rotation of a main shaft. Featuring a compact structure and small footprint, the device utilizes high-purity copper conductors that offer a large contact area and excellent conductivity, ensuring low temperature rise during long-term operation and high stability. Available models include the standard GN30-12 and the GN30-12D (equipped with a grounding switch), with rated current specifications of 630A, 1000A, and 1250A.A range of rated current options is available.
