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?
