The ABB 3AXD50001057626 is an ACS880-37-0640A-5 drive, frame R8i+R8i, built for 3-phase 380-500 VAC supplies. It delivers 450 kW in normal use (640 A continuous) and 315 kW in heavy-duty use (479 A). That heavy-duty current is the number that governs motor starting and overload cycles — the drive will hold that rating through the duty cycle without derating.
The heavy-duty current (479 A) is the one that decides whether the drive handles a real motor load without tripping on startup. The light-overload rating (614 A, 400 kW) sits between normal and heavy — useful if you have intermittent peak loads but not continuous full current. Both UL columns mirror the IEC heavy-duty and light-overload currents, so the same numbers apply for a UL-listed installation.
The drive carries IP22 protection and a NEMA 1 enclosure for indoor use. Altitude rating is 1000 m; operating humidity range is 5-95% RH.
Panel considerations
Frame R8i+R8i is a large cabinet-mount chassis. The WEEE category (4, large equipment) confirms physical size over 50 cm in any dimension. Plan for crane or lift handling during installation — this is not a one-person mount. The lithium coin cells (BR2032, 2 pcs) on the control board keep the real-time clock and parameter backup alive; they're field-replaceable without sending the drive back.
