VCB (vacuum circuit breaker) is used in HV (high voltage) applications.
ACB (air circuit breaker) is used in LV (low votage) applications.

EDO MEANS ELECTRICALLY DRAWN OUT i.e SPRING IS CHARGED WITH MOTOR MDO MEANS MANUALLY DRAWN OUT i.e SPRING IS CHARGED MANUALLY BOTH ARE DRAWN OUT BUT DIFFERENCE IS WHEATHER SPRING IS CHARGED WITH MOTOR OR BY MANUAL. EDO Can be charged manually also.It comes with motor for spring charge and can be charged manually also. no need to wait, operation will be done automatically. Normally whereevr power switching is there we require EDO.
difference between cost and costing
difference between broker and commission agent
there is no difference.
vcb and acb
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.
there is three difference in ACB and MCCB, 1- ACB on off operation is easy as com pair to mccb because acb having charged spring force. 2- acb having much delay time period (category A) and mccb having low time period (category B) 3- the main diffidence is that acb having high raptching capacity and mccb are low.
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.
Arc developed during closing/opening operation is extinguished by air in ACB and by oil in OCB

College ACB was created in 2008.
