VS1 (model ZN63-12) is a technically mature high voltage vacuum circuit breaker for indoor AC use, rated voltage 12KV, rated current 1250A, widely used in various distribution networks as a key element for power control and protection.
The product is made with fixed installation, its arcing and insulating environment is high vacuum space, which provides significant advantages: completely sealed, long service life, maintenance-free. The main component, the vacuum arc chute, is located in the pole and is quickly switched on and off via a high-performance spring drive. This switch has a high short circuit interrupting capacity (typically 25 kA to 31.5 kA), quickly breaking fault currents, protecting the equipment on the line.
The VS1 circuit breaker has a compact design and can be perfectly combined with main distribution cabinets such as KYN28A. Its drive mechanism is integrated with reliable anti-jumping and anti-locking devices, ensuring safe operation. With excellent interrupting performance, long electrical life, reliable and safe operation, and environmental friendliness, VS1 (ZN63-12) has become an ideal choice for power plants, substations and power centers of industrial and mining plants in medium voltage systems.
