The Basics of Circuit Breaker Maintenance | Electrical

In a pure vacuum, there can be no arc. Even though the vacuum in vacuum bottles is very good, it isn’t perfect — so some arcing does take place. The arc is interrupted very quickly, usually in two to three cycles, depending on the appliion. Photo 13 is a vacuum bottle cut-away to show its components.
