( Re: WHAT SHOULD BE THE RATING OF MCCB FOR 415V,3Ph,50KVAR
CAPACITOR BANK
Answer
# 1 The capacitor current would be kvar x 1000 / (415 x
sqrt3). This would be 70a approx. The MCCB selected should
have *atleast 1.4 times this current i.e. 1.4 x 70= 98. So
you should choose at least 100 A mccb.)
regarding to this answer,i would like to know why the
current have to times 1.4 to get the right amphere for the
mccb.hows the formula to get the 1.4??tq

Answer / silu pattanayak

While switching the Capacitor, a charging current of 1.4 times the rated value will be taken by the capacitor due to the "transient" phenomena arising during switching. Therefore, a factor 1.4 is used as safety factor to avoid unnecessary tripping during switching.
