The VS1 (ZN63A) Indoor AC High Voltage Vacuum Circuit Breaker is a three-phase AC high-voltage switch component with a rated voltage of 12kV and a frequency of 50Hz, designed for indoor use in power systems. It is commonly used with complete power distribution equipment and serves as a protection and control unit for power grid systems and industrial and mining power equipment. The breaker comes in both movable (handcart) and fixed types, making it suitable for applications that require frequent operation and multiple interruptions of short-circuit currents. Its distributed structure makes it easy to maintain.
