i heard that power factor(PF) is the main concern for
industries, if they are maintaining PF around 0.6 they will
be fined for that. now the question is, how can they improve
the PF ranging between 0.9 to 0.95 which is safe for them
i,e escaping from the fine?

The PF is low because of inductive load. You can improve IT by adding capacitive load. Luckily cap load is loss free.That means you dont pay kwh for it but you must buy and maintain the capacitor and on and off it as necessary at the right amount.
One way to know how much you need, is you must know the load in KW and the pf.
assuming the load is 500 kw and the PF is 0.6 and you want to improve it to 0.95. you can find out the kva demands at this two pf levels
500/0.6=833kva . 500/0.95=526 kva, 833 kva -526kva =307kva
If you add 307kvar into the system in paralel you would improve the pf to 0.95 you can divide this into 8 steps of 40 KVAR each connected accros the 3 phases through an auto PF regulator.Your cap on each step will be rated as 40 kvar at 415 volts (rated voltage) 3 PHASE.
I welcome any improvements or comment about this.

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?
