What the code is
The ABB ACS800-01-0040-3+D150 is a wall-mount AC drive from the ACS800-01 series, listed under Motors & Motor Controls in the Motor Drives class. The suffix +D150 is a factory-fitted option bundle on the base ACS800-01-0040-3 frame, so the order code carries both the rating slot and the option set as a single shippable part number. At 33.11 kg the unit sits in the mid-range of the ACS800-01 wall-mount family — heavy enough that two people or a hoist plan belongs on the rigging step before the cabinet is opened, but well inside the single-cabinet install pattern for this frame.
What the +D150 suffix means for the BOM line
The base code ACS800-01-0040-3 fixes the frame, voltage class and current rating slot in the ACS800-01 catalogue; the trailing +D150 is what makes this specific order code non-interchangeable with the bare 0040-3. A buyer pulling this string for a spare needs the suffix on the PO line — a 0040-3 with the option omitted is a different shippable assembly, even though the power section matches.
