Tips: Difference between Vacuum Contactor and Vacuum Circuit Breaker
- Vacuum Circuit Breaker:
Complete system short-circuit current; High mechanical endurance; It is operated electrically. It is mechanically latched because CB remains closed on system voltage loss; Short circuit let through energy is low; Control power is used for the operation of CB, protective relays, and space heaters.
- Vacuum Contactor:
Endurance is extremely high for mechanical like 1,000,000 processes for up to 630A; It operates electrical only; It uses protective relays for overload protection and fuses for the protection of short-circuit; Control power is used for the operation of contactor, protective relays and space heaters.
