I. What is the VS1 Vacuum Circuit Breaker?

Key Specifications:

• Voltage Range:12kV, 24kV, 36kV, 40.5kV
• Breaking Capacity:20kA, 25kA, 31.5kA, 40kA
• Mechanical Life:10,000–20,000 operations
• Electrical Life:30,000–50,000 operations (depending on load)
• Operating Mechanism:Spring-stored energy

II. Why VS1 VCBs Are Preferred Worldwide

1. Superior Arc Quenching in Vacuum

• No risk of fire or explosion(unlike oil or SF₆ breakers).
• Instantaneous arc extinction(microseconds response time).

2. High Reliability & Long Service Life

• Minimal maintenance(no contact erosion in vacuum).
• Up to 30,000 mechanical operationsbefore major servicing.

3. Compact & Space-Saving Design

• Ideal for urban substations & industrial switchgear panels.
• Easier installation & maintenancecompared to bulkier breakers.

4. Cost-Effective & Efficient

• Lower total cost of ownership (TCO)than SF₆ or oil breakers.
• Energy-efficient operationwith minimal losses.

5. Global Certifications & Compliance

• IEC 62271-100, GB 1984, ANSI C37.06, DL/T 403.
• Certified for global markets (Europe, Middle East, Asia, Americas).

III. Applications of VS1 VCBs

1. Industrial Power Distribution

• Factories, mining, and manufacturing plants.
• Protecting motors, transformers, and switchgear.

2. Utility Substations (12kV–40.5kV)

• Distribution networks in cities & industrial zones.
• Replacing aging oil or air breakers.

3. Renewable Energy Systems

• Solar & wind farms (MV collection systems).

4. Commercial & Data Centers

• Reliable power protection for critical IT infrastructure.

5. Marine & Offshore Platforms

• Compact, explosion-proof designs.
