With years of profound experience in high-voltage vacuum circuit breaker industry, Jecsany Electric focuses on R&D, production and customized matching of ZN63(VS1)-12 12kV 630A indoor high voltage vacuum circuit breakers. We deliver one-stop overall solutions for high-voltage power distribution control and protection for industrial & mining enterprises, power plant substations and other fields.

1. Core Application Scenarios

Rated voltage: 12kV, rated frequency: 50Hz, suitable for three-phase AC power systems with wide application range:

• High and low voltage power distribution systems of industrial parks, control and fault protection for high-voltage motors and transformers;
• Incoming and outgoing line protection for power plants, urban & township substations and switchgears;
• Power distribution sites requiring frequent operation such as petrochemical industry, rail transit and commercial complexes;
• Perfectly compatible with mainstream switch cabinets like KYN28, available in fixed installation and truck-mounted assembly modes, ideal for all kinds of indoor high-voltage power distribution projects.

2. Product Material & Structural Technology

• The core arc extinguishing unit adopts high-quality vacuum interrupter with excellent sealing and insulation performance. It produces no oil pollution and SF6 gas pollution, featuring stable arc extinction and zero explosion risk.
• Insulating parts are made of epoxy resin composite insulating cylinders, featuring high voltage resistance, ageing resistance and moisture resistance, suitable for harsh temperature and humidity environments.
• High-quality conductive materials are used for conductive loops with low contact resistance and stable current carrying capacity. Rated current ranges from 630A to 3150A with multiple specifications available.
• Adopts integrated modular structure with compact layout and high mechanical precision, reaching seismic resistance grade 8.

3. Installation & Operation Instructions

• Flexible installation methods: fixed type embedded cabinet installation and truck-mounted chassis assembly, easy installation, disassembly and strong interchangeability.
• Optional CT17, CT19 spring operating mechanism and CD17 electromagnetic operating mechanism, realizing manual, electric closing/opening and remote control.
• Standard operating sequence: O-0.3s-CO-180s-CO, opening time less than 80ms, fast short-circuit breaking response.
• Wide applicable working conditions: altitude ≤1000m, ambient temperature: -30℃~+40℃ (operating temperature: -10℃~+40℃), daily average humidity ≤95%. It can operate stably in environments without corrosive and flammable explosive gas.
• Low daily maintenance requirement. No maintenance needed for vacuum interrupters, only regular inspection on mechanism lubrication and fasteners is required.

4. Core Product Advantages

• Excellent performance: optional short-circuit breaking current 20KA/31.5KA/40KA, mechanical life up to 10,000 times, rated short-circuit breaking life up to 30/50 times for long service life.
• High safety and reliability: fully compliant with power frequency withstand voltage and lightning impulse withstand voltage standards, high insulation protection level, no oil spraying or hidden explosion danger, low operating noise.
• Strong compatibility: standard dimensions fit most mainstream 12kV switch cabinets in the market, universal interchangeable with similar products, applicable to new construction and renovation power projects.
• Stable and durable: moisture-proof, condensation-proof and earthquake-resistant, adaptable to high-humidity southern areas and low-temperature northern areas for storage and operation.
• Cost-effective: integrated design saves installation time and labor cost, with extremely low later maintenance cost, the preferred equipment for high-voltage power transmission and distribution systems.
