That is the rating that decides the motor it can run, so anything above roughly a 3 kW 4-pole induction machine is out of frame for this code. It is built as a wall-mount package at 5.62 kgs, meaning one tech can lift it onto the backplate without a second pair of hands or a rigging point. In a control room or MCC cubicle that is the difference between a one-person swap and a planned shutdown window. The enclosure rating carried on the listing is UL Type / NEMA 1, marked twice on the spec rows for the option slot. That class is the indoor, drip-shed, cabinet-or-room-ambient rating — fine behind a panel door, not a washdown field enclosure. ## Where this class of drive gets used A 3 kW 380-480 V drive in this frame typically runs small pumps, fans, mixers and conveyor drives in light-industrial cells — anywhere the motor is on the same three-phase plant as the cabinet and the enclosure is indoors. The 50/60 Hz listing covers both European and North American mains without a transformer tap change. Because it is a US-installation NEMA-rated build rather than an IP21 / IP54 European wall-mount, it drops cleanly into a North American MCC or a US-spec skid where the enclosure language is NEMA 1 from the rest of the lineup. Commissioning the fieldbus slice and I/O map is the same workflow as the rest of the ACS550 family — that is the part of the job that does not change with current rating.","metaTitle":"ABB ACS550-U1-06A9-4 AC Drive, 6.9 A / 3 kW","metaDescription":"ABB ACS550-U1-06A9-4 AC drive, three-phase 380-480 VAC at 6.9 A (3 kW), UL Type / NEMA 1 enclosure.
