| A 3PH MOTOR RUNNING IN NORMAL CONDITION AND ITS AMPERE ALSO
UNDER ITS FULL LOAD CURRENT,ITS CABLE RATINGS ALSO HIGER
THN ITS CAPACITY,BUT ITS CABLE GETTING ABNORMAL HEAT(NOT
TOO HOT)WHY ITS GETTING HOT LIK THIS?

| ( 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

| hi i am aziz electrical associate engineer. i am faceing
problem in acs800 vvvf drive.it is tripping wothout any
alarm/fault.i cheaked all parameters and fault function of
drive, all are correct as well as communication
parameters.but still it is tripping (drive is tripping in
running position not in starting) |
