At 16.78 kg the unit is a one-person lift onto a vertical surface, but the thermal mass is the real figure that matters: 22 kW of inverter loss and cooling airflow want genuine clearance top and bottom, so do not crowd it between a heat-producing contactor above and a cable trunk below. ## Rating so-what for the panel builder The 45 A output and 22 kW rating at 380-480 VAC come from a single spec row; size upstream branch protection and motor cabling off the 45 A figure for that voltage class.","metaTitle":"ABB ACS550-U1-045A-4 drive, 45 A, 22 kW, 480 V","metaDescription":"ABB ACS550-U1-045A-4 AC drive, 45 A at 22 kW on 380-480 VAC three-phase, UL Type/NEMA 1 enclosure.
