The 7.5 kW G120X in its standard-catalog form: the FSC frame at 230 V, 28 A LO for pump and fan duty, 37.8 A max, unfiltered and IP20. The P at the end of the order number marks the standard catalog line - electrically identical to its F twin.

What does the P at the end of the order number mean?

P and F are two ordering designations for the same drive: same frame, same ratings, same I/O. The P line is the standard catalog entry; the F line is the alternative ordering designation. The choice between them is a channel decision, not a technical one - when the catalog line is what the procurement system quotes, the P drive is the one to put on the order.

Is the 7.5 kW LO rating the right match for the load?

The LO rating is written for pump and fan duty: 110% for 60 s in a 300 s cycle covers the soft start and running profile of quadratic loads, where torque grows with speed squared and the drive runs mostly below full load. A load that demands hard starts or sustained overload should be checked against the HO rating instead - at 150% for 60 s this same hardware is rated 5.5 kW, so a load checked against HO avoids a drive that trips on every start. The 3YC22 5.5 kW step covers the smaller line when 7.5 kW is more than the station needs.
