The CRM (Capacitor Rating Multiplier) value for a 6.6 kV VCB (Vacuum Circuit Breaker) typically depends on the specific application and system requirements. However, CRM values are often used to determine the appropriate capacitor bank size needed to support the circuit breaker operation and maintain system stability. It is advisable to consult manufacturer specifications or system design guidelines to ascertain the exact CRM value for your specific application.

The VCB yard us basically a yard that uses the Vacuum Circuit Breaker.

High current coming now that's why use the vcb
acb means AIR CIRCUIT BREAKER ,& vcb means VACUUM CIRCUIT BREAKER
Vcb is what is measured in a particular circuit. Vcbo is the manufacturer's maximum for base-emitter voltage.
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.

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.
