Drive selection memo — 90 kW, 169 A, Frame R7
The ABB 3ABD00046391 is an ACQ531-01-169A-4 AC drive rated for 90 kW normal-use output at 169 A, with a light-overload rating of 90 kW at 161 A. It runs on a 380-480 V three-phase supply, 47.5-63 Hz input, and sits in a frame size R7 enclosure — IP20, open type, so it's meant for cabinet mounting, not standalone washdown duty. Standby loss is 36 W — that's the heat it dumps into the panel when idling, so factor that into your enclosure cooling calc. Efficiency is IE2 class, which is the baseline for this power band; not premium, but meets current minimums for most industrial applications. Maximum ambient is 40 °C — no derating headroom above that without dropping output current. The WEEE category is 4 (large equipment over 50 cm), so end-of-life disposal routing is straightforward for EU compliance.
The light-overload rating (IlD) at 161 A is the same power but slightly lower current, which matters if you're driving a variable-torque load like a fan or pump where peak demand is lower than constant torque. Frame size R7 tells you the physical footprint and mounting pattern — it's a specific bolt-hole layout and duct flange size. If you're swapping into an existing panel, verify the R7 cutout matches your enclosure's gland plate and bus bar positions. IP20 open type means no ingress protection against water or dust — it's strictly for clean, dry indoor cabinets. Not for washdown zones or outdoor kiosks without a secondary enclosure.
