What the order code is
The ABB ACS850-04-018A-5 is a catalogued industrial drive in the Motor Drives line, classed under Motors & Motor Controls, branded ABB and identified on the line as part number ACS850-04-018A-5. The only quantitative figure on the spec sheet is a unit weight of 2.27 kg, which sets the handling reference for the panel builder and the shipping spec, not a selection parameter for the drive's electrical fit. The ABB designation ASEA BROWN BOVERI appears in both the title and description fields, so the buyer's AVL trace and the PO line resolve to part number ACS850-04-018A-5.
