FAQ

1: What is the rated voltage and mechanical lifespan of the ZN63A(VS1)-24 VCB?
The ZN63A(VS1)-24 features a rated voltage of 24kV and a rated frequency of 50Hz. Built for high-frequency industrial utilities, its robust spring operating mechanism provides a mechanical endurance of over 20,000 operations, ensuring long-term reliability for your grid protection.

2: Can this vacuum circuit breaker be integrated into standard KYN28A switchgear cabinets?
Yes, absolutely. The ZN63A(VS1)-24 is engineered specifically as a handcart-type or fixed-type unit that seamlessly integrates into KYN28A-24 metal-clad switchgear and other standard air-insulated switchgear cabinets. We can customize the interlocking dimensions based on your specific cabinet drawings.

3: Does your ZN63A(VS1)-24 VCB comply with international IEC standards?
Yes. As a quality-driven manufacturer, all our vacuum circuit breakers are fully compliant with IEC 62271-100 (High-voltage switchgear and controlgear – Part 100: Alternating-current circuit-breakers) and Chinese GB1984 standards. Routine test certificates can be provided with your shipment.

4: What are the standard ambient operating conditions required for this indoor VCB?
For optimal performance, you should install the breaker in environments where the ambient temperature ranges between -15°C and +40°C. The site altitude should not exceed 1,000 meters, and the daily average relative humidity must remain below 95% to prevent internal moisture tracking.

5: Do you offer OEM/ODM customization for buyers and wholesale orders?
Yes, we provide full OEM/ODM customized services for global EPC contractors and industrial distributors. You can specify custom secondary wiring diagrams, shunt trip voltages (AC/DC 110V/220V), and brand labeling. Contact our engineering team for a wholesale quotation tailored to your project scope.
