VACUUM BOTTLE CIRCUIT BREAKER Application and Testing
... The Importance of Vacuum Interrupter Testing The vacuum interrupters in vacuum breakers do not last forever. Leakage starts after years or decades and the air finds its way in the interrupter, making the breaker unreliable. In most cases, the leakage process is rapid once it has started. In addition ...

Circuit breaker
A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and interrupt current flow. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation. Circuit breakers are made in varying sizes, from small devices that protect an individual household appliance up to large switchgear designed to protect high voltage circuits feeding an entire city.
