What the order code identifies
The ABB ACS550-U1-180-4 sits in the ACS550-U1 series of AC drives on the Motors & Motor Controls / Drives / Motor Drives line, with the model string carrying the U1 wall-mount frame suffix that the rest of the series shares.
Sourcing and lifecycle stance
ACS550-U1-180-4 has no production-status field in the seed record, so the lifecycle stance is quoted-to-order against an RFQ; spec the seed order code on the BOM line and we will source through independent ABB drive channels.
