The ABB ACS550-U1-075A-2+B055 sits in the ACS550 family as a wall-mount Motor Drive, ordered as a single part number for the BOM line rather than a modular build. It is a general-purpose industrial AC drive sourced to specification through the ABB channel and quoted to order against an RFQ; the listing on this desk carries the ABB order code and series identity, nothing more. The unit weighs 31.75 kgs, which is the figure that actually drives handling — a two-person lift onto a wall bracket, and a cabinet deep enough to clear the heatsink profile. Plan the gland plate and the panel cutout against that mass before the drive lands on site, not after.

Product details
Frequently asked questions
What is the listed part # for this Motor Drive?
The part # is ACS550-U1-075A-2+B055, and the +B055 suffix is a factory option that travels with the order code — quote the full string, not just the base drive.
Will ACS550-U1-075A-2+B055 drop into a panel specified around ACS550-U1-072A-4+B055+L512 without rewiring?
No — the ACS550-U1-072A-4+B055+L512 is a 400-volt-class ACS550 with the +L512 option and a 34.02 kgs frame, not a same-class substitute for the 200-volt-class seed with the +B055 option. Specifying a drop-in requires matching voltage class, current, frame, and the full option string first.
