    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.

    Reliable 15 kV vcb breaker
    These remain trusted 15 kV vacuum circuit breaker because of how easy they are to install and how durable they are. In all the years they've been around, we've never replaced a single one that we previously installed.
