What the buyer is specifying
The ABB ACS550-PD-023A-4 sits in the ACS550 series as a motor drive — the part code itself, ACS550-PD-023A-4, is the order string the panel builder or MRO planner drops on the BOM line. At 15.88 kg, the unit lands in the range where a single technician can position it on the backplate with a panel cutout, but it still wants a two-person lift off the pallet and a reinforced DIN/mounting plate.
What the headline ratings tell the buyer
The only quantified figure on the spec sheet for this order code is the 15.88 kg mass — the ACS550-PD-023A-4 datasheet is where the current, voltage frame, and overload profile live, not in this row.
Sourcing posture and cross-shop view
ABB is the listed brand for the ACS550-PD-023A-4, so any quote, compliance doc, or firmware update traces back to the ACS550 series through ABB.
