The ABB ACS380-040S-04A0-4+N2004+X1651 is a configured AC drive from the ACS380 family — the base frame is ACS380-040S-04A0-4, and the trailing +N2004 and +X1651 are factory option codes that change what ships out of the box, not the drive class itself. Those two suffixes are the procurement-relevant part of this string. The drive is sourced as one assembled part number; the panel-builder or integrator specifies the configuration up front so the unit arrives ready to mount and wire rather than needing field-installed option modules.
What the listed ratings confirm
The spec row carries a weight of 1.43 kgs, which lines up with the compact end of the ACS380 frame — light enough that a single tech can handle it during a panel build without lifting gear, and small enough that the heatsink envelope won't crowd adjacent wiring duct. Apart from the order-code string, weight, and the Drives / Motor Drives category placement, there are no further functional ratings on this listing. Drive class, voltage rating, current frame, and I/O map are documented in the manufacturer's data for the underlying ACS380-040S-04A0-4 base code, not in the spec row carried here.
Drop-in vs the un-configured base code
Before specifying this part against an existing ACS380-040S-04A0-4 panel, confirm the +N2004 and +X1651 options match what the wiring, control terminals, and parameter map of that panel expect. The two listed peer codes — ACS380-040S-04A0-4 (the base unit) and ACS380-040C-05A6-4+K475 (a different frame/suffix combination) — confirm the family has multiple build variants on the same chassis; do not assume any sibling is interchangeable without checking the option-suffix matrix.
Sourcing posture
Submitting the full +N2004 +X1651 string on the RFQ is what locks the build so a base-code unit without those options does not ship in its place.
