What the line is
The ABB ACS800-U1-0016-7+P90 is an AC drive in the ACS800-U1 wall-mount family, listed on the Motor Drives line at 25.85 kg, and it carries the +P90 option suffix that ABB applies to factory-configured packages on this frame. The order code as drawn — ACS800-U1-0016-7+P90 — is the string a buyer quotes on the BOM; the P90 tail is part of the configured variant, not a separate accessory.
RFQ
