Tips: Advantages of Vacuum Circuit Breaker

1. Vacuum circuit breaker is a self-contained and does not require filling of oil or gas. They do not need auxiliary air system, oil handling system etc. No need of periodic refilling.
2. Rapid recovery of very high dielectric strength on current interruption so that only half cycle or less arcing occurs after proper contact separation.
3. Current interruption occurs at the first current zero after contact separation with no re-striking, making it exceptionally good for capacitor and cable switching and long line dropping.
4. Very high power frequency and impulse withstand voltages with small contact spacing, allowing ease of actuation and timing.
5. Constant contact resistance. In vacuum the contacts cannot oxidise, therefore, their very small resistance is maintained throughout their life.
