The ABB 3AXD50000749973 is an ACQ531-01-03A4-4 drive rated for 1.1 kW normal-use output at 3.3 A, with a light-overload rating of 1.1 kW at 3.1 A. It runs on a 380-480 V three-phase supply, 47.5-63 Hz, and is built in Frame R1 — the smallest frame in the ACQ531 family, sized for compact panel layouts. The IP20 enclosure and NEMA Open Type rating mean it's intended for indoor cabinet mounting, not washdown or outdoor service. Standby loss is 14 W, so the heat load is modest even in a sealed enclosure.
Ratings that matter for your BOM line
The normal-use current (3.3 A) and light-overload current (3.1 A) are nearly identical — this drive is not designed for heavy overload cycles. If your motor draws more than 3.3 A continuously, you need a larger frame. The IE2 efficiency level is standard for this power class; it doesn't carry the premium of IE3 but meets current EU minimum efficiency requirements for most applications. The 40°C maximum ambient is typical for drives in a ventilated cabinet; derate if your panel runs hotter.
Frame R1 drives mount on a DIN rail or screw directly to a backplate. The IP20 enclosure means you need to keep it behind a cabinet door. The 14 W standby loss is low enough that forced ventilation is optional in a moderately sized enclosure, but check the total heat load if you're stacking multiple drives.
