Core Advantages

1. Reliable Technology: Integrated sealed pole design solves environmental tolerance issues; self-flowing ventilation technology overcomes the heat dissipation problem of solid insulation.
2. Maintenance-Free and Cost-Effective: Long-life vacuum interrupter, permanent magnet operating mechanism, and intelligent electronic control unit achieve maintenance-free operation of all components, reducing maintenance costs and downtime.
3. Controllable Quality: Strictly adheres to relevant domestic and international standards; proprietary professional factory enables full-process control, ensuring product consistency.

Core Parameters and Technical Specifications

Note: Models 4000A and above require forced air cooling; custom accessories are available.

Overall Structure

The VCB Vacuum Circuit Breaker is available in two structures: fixed and trolley. The fixed type requires a flat installation and can be adjusted using shims; the trolley type has a 200mm push-in stroke for smooth operation. Both structures offer excellent dust and moisture protection, adaptable to different climates in China.

Core Components

1. Vacuum Interrupter: Long life and stable vacuum, the core component for reliable interruption.
2. Integrated Sealed Pole: Epoxy sealing combined with self-flowing ventilation enhances environmental adaptability.
3. Operating Mechanism: VET or permanent magnet type optional, precise operation, maintenance-free.
4. Electronic Control Unit: Photoelectric proximity switch replaces traditional switch, ensuring precise control.
5. Optional Accessories: Anti-bounce, interlocking, overcurrent tripping, and other devices.

Real-world Application Cases

VCB Vacuum Circuit Breaker has been widely used in various power scenarios in China. The following are real-world application cases with verification materials available:

Case 1: A large coal mine substation in Shanxi Province

Using the Usune ZN63(VS1)-12 handcart-type circuit breaker, suitable for dusty and humid environments, it operated stably for 12 months without failure, saving 8,000 RMB in monthly maintenance costs. Usune, as the core supplier, provided full technical support.

Case 2: A power distribution project in an industrial park in Jiangsu Province

Using the Usune GVS6-12 embedded pole-type circuit breaker, its miniaturized design saves 30% of the distribution room space and successfully avoided three short-circuit faults. The factory controlled quality throughout the process and provided customized solutions.

Product Standards and Environmental Adaptability

1. Standards: Strictly adheres to domestic and international standards such as GB1984, GB/T11022, and IEC56, ensuring quality meets international standards.

2. Environmental Adaptability: Suitable for temperatures ranging from -15 to +40℃, altitudes ≤1000m, and daily average humidity ≤95%, in industrial and mining environments free from fire, corrosion, and strong vibration.

Maintenance and Ordering Instructions

1. Maintenance Instructions

Maintenance-free design. It is recommended to clean the equipment surface every two years, regularly check fasteners, and conduct annual energy storage operation and insulation tests. Maintenance requires professional personnel.

2. Ordering Instructions

Orders must specify: model and quantity, rated parameters, operating voltage, secondary wiring scheme (optional), spare parts, and special requirements. Usune, as a professional manufacturer, provides customization services.

Brand and Service Commitment

Leveraging the advantages of China's industrial chain, Usune has its own standardized factory to achieve full-process control. As a globally trusted supplier, it provides comprehensive services such as installation guidance, commissioning, and operation and maintenance training. Adhering to the philosophy of "quality first, customer foremost," it contributes to the development of the energy industry.
