The VSG-12 Model is an indoor high voltage 12kV 3 Pole High Voltage Vacuum Circuit Breaker designed for power systems with a rated voltage of 12kV. It serves as a protective and control unit for power grid equipment and industrial power equipment. Compatible with KYN28(GZS1), XGN, GG-1A, and other switchgear panels. Related products include isolated handcart, fuse handcart, and voltage transformer handcart.
The VSG series of circuit breakers are suitable for rated voltages of 12-24kV, rated short circuit breaking currents of 20 and 50KA, and rated currents of 630-5000A for power distribution users. With a mechanical endurance of 20000 operations and 50 operations at full capacity breaking ability at small current, it is ideal for frequent operation with minimal maintenance requirements. Can be used with Model KYN28A(GZS1) metal-enclosed switchgear and other fixed or handcart cabinets.
