◆ Product overview

ZN63G(VS1)-24 high prototype indoor high-voltage vacuum circuit breaker is a rated voltage of 24kV, three-phase AC 50Hz indoor high-voltage switchgear, suitable for power plants, substations and industrial and mining enterprises and other transmission and distribution system control or protection switch, especially suitable for high altitude areas to break important loads and frequent operation places.

The manufacture of circuit breakers conforms to China's national standards GB1984-2003 "AC High Voltage Circuit Breaker", JB3855-1996 "3.6~40.5kV Indoor Vacuum Circuit Breaker Order Technical Conditions" and related IEC standards, and has reliable interlocking function.

The operating mechanism of the circuit breaker is spring energy storage, which can be operated by AC and DC energy storage, or manually.

The circuit breaker can also be equipped with a long-life permanent magnet operating mechanism, and the mechanical life can reach 100,000 times, which can be used for more frequent operations.

The circuit breaker is designed in the form of a front-to-rear split-assembly structure, which can be used as a fixed-mounted unit or as a mid-mounted unit with a chassis car.
