As you all knows that all circuit breakers can be called
as on off switch with some safety device ie ACB make and
break contact in air (one moving and one sliding) so it
called air circuit breaker for safety we use in ACB Under
voltage shunt trip closing unit. CBCT for tripping command
relay with over voltage earth fault etc for spring charge
we use motor charging mechanism. Same case with VCB
contacts makes in vacuum to minimize the arc during make
and break contact (one moving and one sliding) on high
voltage other function are same but according to the
