vcb and acb
VCB (vacuum circuit breaker) is used in HV (high voltage) applications. ACB (air circuit breaker) is used in LV (low votage) applications.
acb means AIR CIRCUIT BREAKER ,& vcb means VACUUM CIRCUIT BREAKER
Actually ACB isused for Low Tension side and VCB is used for High Tension Side..Chappa matter

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.
Dielectric Strength of Vacuum is more than that of Air. In HT voltage is more than LT. So VCB is used in HT & ACB in LT. Rakesh Gaikwad
The VCB yard us basically a yard that uses the Vacuum Circuit Breaker.

High current coming now that's why use the vcb
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.
