Construction is listed for US installation and NEMA compliance, so the enclosure, gland plate pattern, and field wiring land in line with the expectations of a US panel builder rather than a CE-only cabinet. It sits in the ABB drives catalog under the broader Motor Drives class, not a specialty or HVAC-only variant. ## Reading the headline rating The 16.7 A / 4 kW output is the figure that actually drives motor pairing — a 4-pole induction motor up to roughly 4 kW is the natural fit, with the 208-240 V three-phase input dictating the supply feed from the MCC. The 50/60 Hz frequency range covers both 60 Hz North American service and 50 Hz export applications without a parameter change. Because the enclosure is UL Type/NEMA 1, the drive is intended for a clean, indoor panel environment — wall- or panel-mount inside a control room — rather than a washdown or outdoor location, so any IP54 or outdoor application has to derate the enclosure choice upward before this drive is specified. ## Handling and panel layout At 5.67 kgs, the unit is light enough for a single technician to lift into place during panel build or field swap-in, and the weight is small enough that standard DIN-rail-style mounting hardware in the surrounding cabinet is sufficient without extra bracing. The NEMA 1 enclosure and US-installation construction mean conduit entries land on the standard US knock-out pattern, so a panel wired for the 240 V three-phase feed can accept the drive without reworking the gland plate. ## Sourcing posture The ACS550-U1-017A-2 is specified into the BOM as a quoted-to-order drive: the part code carries the exact output rating, enclosure, and regional construction the panel is being built around, so a buyer committing the line should quote against the full code rather than a generic 4 kW substitute. A same-series 240 V sibling exists at the 30 kW frame for designs that need to scale up within the same platform; for any other cross-reference, the part must be re-validated against the motor nameplate rather than treated as a drop-in.","metaTitle":"ABB ACS550-U1-017A-2 drive, 16.7 A, 4 kW, 208-240 V","metaDescription":"ABB ACS550-U1-017A-2 UL Type/NEMA 1 drive, three-phase 208-240 VAC at 16.7 A / 4 kW.
