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

Re: york chiller Solid state starter starting current
most soft starters have adjustable ramp up times. DOL starting is something like 10 times the LRA.
