For a buyer staring at a BOM line, the first mechanical decision is handling: the drive ships at 8.16 kgs, which puts it in two-handed panel-mount territory but well short of the hoist-required frames higher in the same family. ## Frame context inside the family The same-family ACS550-U1-096A-4 lands at 19.96 kgs, a larger current/frame class rather than a drop-in alternative to the 06A9-4. Treating the two as a 1:1 panel swap would mis-size the breaker, cabling, and enclosure cooling. If the spec window is being opened to consider the ACH580-01-014A-4 or ACH580-01-023A-4 as successors, note they list at 6.80 kgs each — a different mechanical and firmware generation, not a same-frame substitute, so footprint and parameter set have to be re-verified rather than assumed.","metaTitle":"ABB ACS550-U1-06A9-4+B055 Motor Drive, 8.16 kg","metaDescription":"ABB ACS550-U1-06A9-4+B055 ACS550 series motor drive, listed at 8.16 kgs.
