Hi all. I 'm new at this site. I need your helps.
I want to know
How much current is occur when I start York 400t chiller with solid state starter.
chiller spec says that the rated amps is around 300A, but when I start it, it looks like use much more than 300A.
Anybody know about starting current, please help me:confused:

You need to check the motor datasheet and look for the Locked Rotor amps value (LRA). A typical solid state starter inrush will in the 45 to 50% of the LRA value

most soft starters have adjustable ramp up times. DOL starting is something like 10 times the LRA.
