VCB is batter than ACB.in hv side VCB is used & Lv side ACB is used current rapturing in vacuum is more effective than air

Answer / sanjeev

VCB Instal in HT side lower current & high voltage also HT
side instled ACB in stale in LT side high current upto
rating capacity lower volltage also used ACB LT side & VCB
HT side

Answer / arun pandey

It depends upon the application.
For lower voltage and current rating and at lower cost ACB
is better
and for heigher power rating VCB is better

Answer / farhan shaikh

acb is used upto LOW VOTAGE UPT 1kV AND VCB IS USED FOR HT
IN LIKE 3.3,6.6 kV

Answer / venkatesh s.r

Its depending upon application of usage.
VCB:It is using in HT side because of it will carry high
voltage &low current.
Example: in Ht side voltage is 11KV &current lee than 600
Amps

ACB:It is using in LT side because of it will carry high
current &low voltage.
Example: in LT side current is depending upon load &
voltage is 430 only.

Answer / jaimin

We are use ACB in LV system because of Low voltage & its
spark also low compare to HV system so that other
accessories use for ARC extinguisher size less than to HV
system.

But same system use in HV system need more size compare to
LV system for ARC extinguisher so we are use VCB design for
HV system & ACB design for lV system, All are suitable as
per respectively.
