What this order code is
The ABB ACS800-01-0009-3+E202+P901 is a wall-mount single AC drive from the ACS800-01 series, ordered with the +E202 and +P901 factory option codes built into the configured string. It sits in the Motor Drives class — a frame built for cabinet mounting on a typical industrial MCC back-plate.
What the option string tells the buyer
Configured ABB ACS800 codes ship with the +E202 and +P901 selections already fitted — they are not field-installable accessories. Procurement needs to specify the full string including those suffixes so the drive arrives with the firmware, option card, or hardware variant the panel was engineered around. Because the option codes are baked into the part number, two ACS800-01-0009-3 drives with different suffix strings are NOT identical units and the substitution question has to be answered against the full code, not the base frame.
