What it is
The ABB ACS550-01-08A8-4 is a member of the ACS550 series low-voltage AC drive family, ordered under that exact order code and falling within the Motor Drives line. At 2.77 kgs the unit sits in the small-frame class typically mounted inside a panel rather than on a machine surface. The listing carries no explicit production-status row. With no lifecycle entry on file, status is not asserted here — specify the order code into the BOM and request a quote against the RFQ, where lead-time posture and any factory-channel constraint surface directly.
Sourcing posture
For a procurement line built around the ACS550 series, the practical move is to list ACS550-01-08A8-4 as written on the BOM and let the quote carry the timing. Because no official successor part number is recorded against this order code in the on-page evidence, no cross-reference is offered — surplus and independent-channel supply are the realistic paths if the factory line is constrained.
