Answer / thiyagarajan r
VCB means Vacuum Circuit Breaker.Vacuum Circuit Breaker is always used in the HT side of the transformer and it act like a On/Off switch and prevent the power system in case of any faults by using Vacuum as the breaking mechanism.

Answer / s b mutha
VCB is used for switching of Transformer. Over current, Short Circuit and Earth fault protection also incorporated in VCB to protect your valueable transformer. During swiching of ON and OFF its contacts make and break in under Vaccum Bottles to protect from heavy spark during fault and on load tripping.

Answer / thakur ankit
VCB= vaccum circuit breaker ...
Breaker disconnect power supply . like your fan an light switch . ON means fan , tv start working that is air circuit breaker ... But when you use high power circuit to disconnect like 11000 kV and 33000 ... The air gap between then is charged and supply might be get some voltage due to air electron get charged that is why we vaccum breaker vaccum.means you understand nothing between them that islive wire and other wire that is off... And above 132 kV u used SF6 circuit breaker
