Answer / logeswaran

AVR is nothing but a automatic voltage regulator.it ill
regulate the field input based on terminal voltage either no
load or full load condition.

if AVR fails in alternator...?

The alternator output we will get only residual voltage at
no load condition based on the residual magnetism.

The residual Approximately for 1 & 3 phase 4 pole alternators:
min:4 V to max: 90 V.

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?
