why always out of the 3 phase(RYB) of supply, in Y phase w.r.t the voltage is higher? on R & B..

Answer / k.prakashchandra

It is not true.In overhead dist system ,the single phase
loads are most likely to be connected to the outer phase
wires with y phase being in the middle and not easily
reachable.Due to heavier loads in the R & B phases the IZ
drops will be more than that in Y phase

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?
