Disappointing about Wolf Automation technical, seems like who you get, others have have mentioned they have been more helpful. Might go to some third party these days. The AuCom seemed to check all the boxes. I like Automation Direct, I use them a lot for automation/control system parts, so glad they could provide more information. The SR33-41 should work if you motor draws 29-30A under full load, the load would be rated class 20 from the description. SR33-55 would be indicated it your motor FLA is over 30A. Frequency of starts is 5 per hour, but this will also be influenced by many other factors, the rated starting capacity for class 20 is 4X the motor current for 19 seconds, I would assume if one shortens the starting time or decreases the starting current it would lower the thermal impact and allow more start stop cycles. Still seems like a SS is an easier install than a VFD.
