744 Amps Chiller without Soft Starter
744 Amps Chiller without Soft Starter
(OP)
Hello,
I am negotiating an electrical installation for some chillers. The manufacturer's catralogue says:
Nominal Power Input: 435 kW
Nominal Current: 744 A
With anominal votlage of 400 V, i get a cos phi = 0.84
I thought that large machines come with soft starters, and that a soft starter would have a pf = 0.98. I may be wrong on one if not on both issues, could you please correct me? thank you.

I will also say this question would be best in the "Electric Motors" forum. A lot of motor guys don't ever look here in Solid State Relays.
