Vacuum circuit breakers
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, by interrupting continuity, to immediately discontinue electrical flow.
Vacuum circuit breakers interrupt the current by creating and extinguishing the arc in a vacuum container.
