What it is on the panel
The ABB ACS800-U1-0020-5+N661+P901 is the ACS800-U1 wall-mount AC drive configured with the +N661 and +P901 option codes, listed under Motor Drives in the ABB drives catalog (, –). It carries the ACS800-U1 single-cabinet form factor used to run induction motors from a panel-front enclosure rather than a cabinet-integrated module. The +N661 and +P901 suffixes encode application-specific option packages; confirm the option breakdown against the drive nameplate before specifying it into a BOM line that originally called for a base ACS800-U1-0020-5.
Handling at the panel
The drive ships at 14.06 kgs per the listing, which is the load a single installer lifts onto the mounting plate — plan for a two-person lift or a panel-side mechanical aid when the cabinet is taller than chest height. No mounting footprint, depth, or cooling-clearance figure is on this ledger, so cabinet cutout and airflow have to be taken from the ACS800-U1 mechanical drawing rather than this row.
