What the order code actually is
The ABB ACS850-04-144A-5+E210+JA00+Q971+R700 is a frequency inverter on the ACS850-04 drive family, configured with the +E210, +JA00, +Q971 and +R700 option suffix string on the listed line. It sits in the Motor Drives class under Drives and Motors & Motor Controls, so the option suffix needs to be read against the ACS850 ordering guide — not a generic ABB drive code — before specifying into a BOM. Listed mass is 15.88 kgs, which is enough to matter for the panel layout and the lift-in step, even though weight does not decide the sizing the way the current and option set do.
Peer contrast — ACS880-01-040A-5 is not a like-for-like
Two further peers sit in the same evidence bundle — DCS880-S02-0200-05X0 at 16.33 kgs and ACS880-01-065A-5 at 23.13 kgs. Both are catalogued as Motor Drives but neither is a frame-, current- and option-matched substitute for the ACS850-04-144A-5 build; treat any cross-reference as engineering review, not a BOM swap.
