Answer / sunil

0.8 lagging and 0.8 lagging only. It is mandatory to have
this pf in DGs.

Answer / mohit

It will depend upon load connected to DG.

Answer / vijay balu raskar

Yes, power factor is 0.85 lagging or more than this. Also, based on operating loads.Because, power factor is the ratio of active power to the appearant power.

Answer / ram khapekar

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?
