VCB means vacuum circuit breaker it used in high voltage
(HV) lines
It has one mechanism in this mechanism spring is there it
is connected with small electric motor for charging the
spring but we can do manually charge also by this spring
tension circuit closing or circuit open can be done. The
circuit closing can be done by (CC closing coil) also.
In VCB CT are used for measuring, controlling & protection
purpose.

ACB means air circuit breaker it is used in low voltage
(LV) lines
It has also one mechanism it also work same.
ACB has (UV Under voltage) it used for tripping purpose
when power fail.
It has (CC Closing coil) for closing the circuit.
CT are used for measuring, controlling & protection purpose
