What the order code covers
The ABB ACS850-SP04-010A-5+SP600 is an AC drive in the ACS850 family, catalogued under Motors & Motor Controls at the top level, Drives in the middle, and Motor Drives as the sub-class. The +SP600 suffix in the order string is a factory-engineered option on the base SP04-010A-5 frame and ships as a single part number to the panel builder.
ACS850 drives are positioned as the machinery-drive tier in ABB's portfolio — used where a standard AC induction or permanent-magnet motor needs controlled torque and speed, typically downstream of a line contactor and upstream of the motor cable glanding. The +SP600 option is the kind of engineering suffix that often denotes a factory-fitted option module or pre-loaded firmware set, so the BOM line should keep the full order string intact when placing the RFQ.
Sourcing posture
Quote the full order code ACS850-SP04-010A-5+SP600 against an RFQ so the +SP600 option is locked into the procurement line; that suffix is the kind of factory build that does not survive a manual reorder on a base part number alone.
