Footprint comes in at 27.1 in tall by 8 in wide by 10.3 in deep, so the panel-builder is sizing a wall cut-out, not a DIN rail — this is a free-standing wall-mount enclosure with the supply cabling landed through the gland plate at the bottom. ## Where this drive slots into the line ACS550-U1 drives are the workhorse for general-purpose industrial motor control — pumps, fans, conveyors, and standard 3-phase induction loads in the 380–480 VAC range, which is exactly the input window this code covers and why it shows up on HVAC, water/wastewater and packaging line retrofits. Wall-mount NEMA 1 is rated for indoor use on a clean wall surface per the listed enclosure; outdoor or washdown duty requires a different NEMA suffix on the ACS550 family. ## Sourcing posture Spec is fully resolved against the order code — 3-phase 480 VAC input, 75/60 Hp dual-rated output, R4 NEMA 1 wall-mount — so the line item can be specified into the BOM against this exact code; quotation is run to order against an RFQ, and the supply picture runs through normal ABB-channel sourcing for active ACS550 product.","metaTitle":"ABB ACS550-U1-097-A4 VFD, 480V 3-Phase, 75 Hp","metaDescription":"ABB ACS550-U1-097-A4 general-purpose drive, 480 VAC 3-phase, 75 Hp normal duty / 60 Hp heavy duty, 96 A / 77 A, NEMA 1 wall-mount R4 frame.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["AC Drive (VFD) 480V"],"specifications":{"Type":"General Purpose Drive","Phase":"3","title":"60 Hp, 75 Hp, ACS550, VFD, N1|3-Phase Supply Voltage, 380 - 480V AC, NEMA 1, Wall Mount Drive. 3-Phase Output, Normal Duty: 75 Hp.
