What is a Vacuum Circuit Breaker? | The Definitive Guide
A vacuum used in a circuit breaker as a means of arc quenching is known as a vacuum circuit breaker. This is because the vacuum superior arc gives high insulating strength due to its decorative properties. Most of these are suitable for standard voltage applications. This technique was developed only for high voltage.
