VCB is Vacuum Circuit Breaker. It is one of the type of Circuit breaker. In VCB arching chamber is vacuum instead of oil or such arc quenching media. Its function is to break the circuit automatically in case of fault or to isolate the circuit under normal situation also.
The VCB yard us basically a yard that uses the Vacuum Circuit Breaker.
Vcb is what is measured in a particular circuit. Vcbo is the manufacturer's maximum for base-emitter voltage.
An air circuit breaker (ACB) can be identified by its open-air design and larger physical size, typically featuring a visible arc chamber where the circuit interruption occurs in open air. In contrast, a vacuum circuit breaker (VCB) is generally more compact and sealed, with its main components housed in a vacuum chamber, allowing for efficient interruption without an external medium. ACBs usually have visible contacts and may show wear over time, while VCBs feature a smooth operation and minimal maintenance due to their protective environment.
In VCB, The two contacts are present in a vaccum, When there is a fault these contacts are forced to open resulting arch ,as all we know arch does not flow through Vaccum so it extinguishes thus vcb seperates two circuits.

High current coming now that's why use the vcb
acb means AIR CIRCUIT BREAKER ,& vcb means VACUUM CIRCUIT BREAKER

It should be something about 70 micro Ohm for VCB with two breaks per pole and about 30-40 micro Ohm for one break VCB
VCB (vacuum circuit breaker) is used in HV (high voltage) applications. ACB (air circuit breaker) is used in LV (low votage) applications.
