VS1 (ZN63A)-24 series indoor high-voltage vacuum circuit breaker is an intelligent switchgear designed for 24kV, 50Hz indoor power distribution system, integrating protection and control functions, suitable for industrial and mining enterprises, power plants and substations of high-reliability power scenarios. Using vacuum arc extinguishing technology, short circuit current breaking capacity of 25kA-31.5kA, mechanical life of more than 30,000 operations, in line with GB/T 1984-2014 and IEC 62271-100 standards. The modular handcar design ADAPTS to the KYN series switchgear with IP4X protection class, withstands extreme environments from -25°C to +60°C, supports quick plug and pull maintenance and intelligent condition monitoring (optional), and provides a "maintention-free, long life" power protection solution.

Mid mounted PT Handcart indoor vacuum circuit breaker is a high-voltage switchgear with a mid mounted integrated voltage transformer (PT), designed specifically for 40.5kV indoor distribution systems. Adopting vacuum arc extinguishing technology, the short-circuit current breaking capacity reaches 40kA, the mid mounted handcart structure saves 50% of installation space, and supports the integration of PT voltage monitoring and protection functions. Compliant with GB/T 1984 and IEC 62271-100 standards, with a mechanical lifespan of over 10000 cycles and a protection level of IP4X, it is compatible with KYN series switchgear and suitable for scenarios such as data centers, industrial and mining power distribution, and rail transit, achieving intelligent power protection with "high-density, zero SF6 emissions".

72.5kV outdoor high voltage vacuum circuit breaker is designed for harsh environment, using fully sealed stainless steel housing and vacuum arc extinguishing technology, with explosion-proof, anti-corrosion, anti-ultraviolet performance, adapt to -40℃ to +40℃ extreme temperature. Rated short circuit breaking current 31.5kA, mechanical life 10,000 times, maintenance-free structure significantly reduces operation and maintenance costs, suitable for substations, industrial and mining distribution and wind power/photovoltaic high voltage grid-connected systems, in line with IEC 62271 and GB standards
