Schematic Diagram Of Vacuum Circuit Breaker

vacuum circuit breaker vcb principle construction and. vacuum circuit breakers are employed for outdoor applications ranging from 22kv to 66kv even with limited rating say 60 to 100mva they are suitable for the majority of applications in rural areas the working of vacuum circuit breakers is briefly explained below when the breaker operates the moving contact separates from the fixed contact and an arc is struck between the contacts.
