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.
You can identify Air Circuit Breakers (ACBs) and Vacuum Circuit Breakers (VCBs) based on their construction, arc-quenching medium, and applications: Arc-Quenching Medium ACB: Uses air at atmospheric pressure to extinguish the arc. VCB: Uses a vacuum inside a sealed chamber as the arc-quenching medium. Voltage Range ACB: Commonly used for low voltage (LV) applications, typically below 1,000V. VCB: Used for medium voltage (MV) applications, typically 11kV–33kV. Construction & Size ACB: Larger in size with visible arc chambers. VCB: More compact with sealed vacuum interrupters. Applications ACB: Ideal for industrial, commercial LV panels where frequent switching is required. VCB: Suitable for medium-voltage substations and industrial MV panels where safety and reliability are critical. Maintenance ACB: Requires more periodic maintenance due to open-air arc quenching. VCB: Low maintenance because vacuum interrupters prevent oxidation and corrosion. For authentic ACBs, VCBs, and other electrical products, you can explore SmartShop by Lauritz Knudsen. They offer genuine electrical solutions for industrial, commercial, and residential applications.
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.
