On the panel-builder's side the unit weighs 43.09 kgs, which is the number that decides lifting, mounting-bracket sizing, and whether the cabinet needs a removable top hat or a floor-standing enclosure rather than a wall-mounted box. ## Where the frame sits against its siblings Against the lighter ACS550-U1-059A-4+B055 at 36.29 kgs and the ACS550-U1-072A-4+B055+L512 at 34.02 kgs, the -078A-4 at 43.09 kgs is the heavier frame in this comparison set — the weight gap is large enough to imply a different current/horsepower rating and almost certainly a different footprint, so it is not a panel-for-panel swap against either -U1 sibling. Stacked against the ACS580-01-180A-4 at 54.43 kgs, the -078A-4 sits one frame size below the ACS580 generation, which is consistent with the ACS580 being ABB's successor platform and the ACS550 family now sitting in the mature-generation slot buyers cross-reference for spares rather than greenfield spec. ## Sourcing posture","metaTitle":"ABB ACS550-PD-078A-4 AC Drive, 43.09 kg","metaDescription":"ABB ACS550-PD-078A-4 AC drive in the ACS550 family at 43.09 kg.
