What the code puts on the line
The ABB ACS550-U1-015A-4 is a wall-mount AC drive rated 15.4 A at 380-480 V three-phase, 50/60 Hz, which lands it at the 7.5 kW output point for that voltage window. The enclosure is UL Type/NEMA 1, built for US installation practice — an indoor cabinet-mount unit, not a stand-alone floor enclosure. At 9.07 kgs it is a one-person carry into a wall-mount cabinet, but the mass still wants the back panel sized to take the steady-state vibration a drive like this puts into a sheet-metal enclosure.
