Vacuum Interrupter for Vacuum Circuit Breaker – Reliable Arc Quenching for Superior Electrical Protection
Ensure safe and efficient power distribution with our high-performance Vacuum Interrupter, the core component of Vacuum Circuit Breakers (VCB). Engineered for medium-voltage applications (7.2kV-40.5kV), our interrupters deliver fast arc extinction, minimal maintenance, and long service life—making them ideal for power grids, industrial plants, and renewable energy systems.
Key Features & Benefits
✔ Ultra-Fast Arc Extinction – Vacuum technology ensures arc interruption in <10ms, preventing contact erosion
✔ Maintenance-Free Operation – Hermetically sealed ceramic or glass enclosure eliminates gas leakage risks
✔ High Breaking Capacity – Rated for 20kA-50kA short-circuit currents with consistent performance
✔ Long Electrical Life – CuCr (Copper-Chromium) contacts withstand 30,000+ operations
✔ Compact & Lightweight – 50% smaller than SF6 alternatives for easy retrofitting
Critical Applications
- Switchgear Panels (VD4, VEP, VBM series)
- Wind/Solar Farm Protection Systems
- Mining & Oil/Gas Industry Power Networks
- Railway Electrification & Smart Grids
Why Choose Our Vacuum Interrupter?
✓ Zero Emissions – Environmentally friendly vs. SF6 gas interrupters
✓ Customizable – Multiple contact diameters (30-80mm) and shield configurations
✓ Certified Compliance – Meets IEC 62271, ANSI C37.04, GB/T 11022 standards
The smart choice for modern power systems requiring fail-safe interruption!
