What this drive is
The ABB ACS800-U1-0120-7+L503+N683+P901 is a wall-mount AC drive from the ACS800-U1 family, factory-configured with the +L503, +N683 and +P901 option codes that ship integrated into the unit's order string. It sits in the Motors & Motor Controls › Drives › Motor Drives category, so it's specified as a stand-alone cabinet-edge drive rather than a module or starter. The listing carries the ABB brand and the standard ACS800 catalog line for industrial drives.
