What the catalog line actually carries
Listed part code is ACS800-U2-0300-5 and listed mass is 449.96 kg — write both onto the BOM line as printed; a junior should not strip the suffix when transcribing into the parts list. Brand on record is ABB, per the lifecycle entry for this code.
Where the ACS880 peers sit — reference only
ACS880-01-156A-5, ACS880-01-065A-5 and ACS880-01-040A-5 (–) appear in the same Drives / Motor Drives class and are listed at 55.00 kg, 23.13 kg and 18.14 kg respectively. Those ACS880 entries are next-generation ABB drive references for a panel-migration conversation; the mass gap to ACS800-U2-0300-5 at 449.96 kg is large enough that a like-for-like mechanical drop-in is not assumed — confirm frame, current class and footprint against the target ACS880 datasheet before any swap.
