    What is diff between Vacuum contactor (with fuse) and Vacuum Circuit Breaker? Which one is better for motor control? Is there is any criteria for selection?

    A circuit breaker offers short circuit protection only

    A contactor is also known as a motor starter. With fuses it offers short circuit protection and has other devices builtin to offer overload protection.
