What will be the average KVA rating of Auto Transformer
for 75kw 415V , 3phase induction motor
Answer Posted / baikunth
motor rating in kva = 75/0.5=150kva
so the apparent power is let 200kva.
Keeping the starting condition and fault conditions like
overload,single phasing etc. I suggest 200x3=600kva or
750kva a standard value for the motor of 75kw,supposing that
transformer ration is 1:1.

I have an existing old MCCB. ABB Model SACE, the rating are: Ue = 660 volts, Iu =1250 Amps, 3 poles, Ith (max) =800 amps at 45 deg C. I need a circuit breaker for my 3 phase motors, 380 volts 60 hz. the supplier required the minimum ampacity of the breaker to be 911 amps. can i use this breaker with rating of Iu =1250 amps but Ith = 800amps maximum?
