　　Product Positioning: This is a center-mounted, sealed-pole vacuum circuit breaker. It utilizes vacuum interrupter technology, offering high reliability and fast arc extinguishing, suitable for high-frequency operation scenarios (such as industrial power distribution and power substations).

　　Technical Parameters and Performance

　　Basic Parameters:

　　Rated Voltage: Matches the system voltage level (e.g., 10kV, 35kV). The maximum operating voltage is 1.1-1.15 times the rated voltage (e.g., 12kV/13.2kV for a 12kV system).

　　Rated Current: 2000A (some models support extensions such as 1250A and 2500A).

　　Interrupting Capacity: Short-circuit breaking current 25kA-50kA, short-circuit making current up to 102kA (peak), meeting the needs of high short-circuit capacity scenarios.

　　Mechanical Life: 10,000-30,000 operations (spring mechanism), electrical life 30-50 full-capacity interruptions.

　　Opening and Closing Time: Opening time 25-40ms, closing time 50-100ms, overtravel 3-5mm, ensuring contact maintains good contact even after contact wear.

　　Insulation and Protection:

　　Lightning impulse withstand voltage 75kV (peak), power frequency withstand voltage 42kV (1min), suitable for high altitude (derating required) and humid environments (IP54/IP65 protection).

　　The operating mechanism adopts a spring energy storage design, supports both electric and manual operation, and is anti-condensation and low-temperature resistant (-40°C).

　　Power Distribution: Widely used in 10kV-35kV power distribution systems as incoming and feeder circuit breakers, ensuring stable grid operation.

　　Industrial Applications: Suitable for high-load industrial environments such as metallurgy, petrochemicals, and mining, supporting frequent starts and stops and short-circuit protection.

　　New Energy: Used as grid-connected circuit breakers in wind and photovoltaic power plants, meeting low voltage ride-through and dynamic braking requirements.

　　Special Environments: Customized weather-resistant models are required for high-altitude, high-humidity, and low-temperature regions (such as Northeast China and the Qinghai-Tibet Plateau).

　　Installation and Maintenance Key Points

　　Installation Specifications:

　　Mechanical Installation: Use flange or threaded mounting. Ensure adequate access (≥1.5m in front of the cabinet, ≥0.8m in back of the cabinet) and avoid humid or corrosive environments.

　　Electrical Connections: Properly connect the 24V DC power supply and fiber optic interface to prevent electrostatic damage. For IGCT modules, ensure crimping pressure and heat dissipation contact.

　　Cooling System: An aluminum alloy heat sink is recommended to keep the module junction temperature below 100°C. The closed-loop water cooling system requires a redundant pump design to maintain optimal water temperature.

　　Maintenance Requirements:

　　Regular Inspection: Verify component integrity, wiring security, and cooling system operation monthly, and replace filters and seals.

　　Troubleshooting: Use LED status indicators or diagnostic tools to locate faults (such as abnormalities on the axis computer board or driver board). Professional intervention is required.

　　Cleaning and Maintenance: Keep the cabinet interior clean and perform insulation resistance testing (≥100MΩ @500VDC) using specialized tools.

　　Certifications and Standards

　　International Certifications: Complies with IEC 61800, GB/T 12668, and is ISO 9001:2015 certified for quality management systems. CE and UL certifications are supported.

　　Safety Standards: Meets NFPA 70 (National Electrical Code) and ATEX/IECEx explosion-proof certifications, making it suitable for use in explosion-hazardous areas.

　　Environmental Compliance: RoHS compliant, lead-free/mercury-free, and recyclable.
