Star-Delta motor starting method is for reducing the
starting current by dividing line current with 3 square
that is considered in 3 phase only, and also most of single
phase motors are small motor having small starting current
so it is no point to reduce the starting current.

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?
