I would second Elevator_Steve. Both S&S and Siemens can be configured to run in-line or wye delta. But you always have to up size the starter 1 or 2 sizes and also make some wiring changes to the soft start. Both brand starters should have ratings for both types of starting on their data tag and in their installation manual.

I will say I have seen a lot of older jobs were the controller has the leads piped across the room to the pump unit and if it is only using 3 leads its certainly a big time saver getting the slightly larger starer and wiring it in-line.
