The ABB 3AUD0000003530 is an ACQ580 series irrigation drive package for 3-phase LV AC motors. It delivers 40 HP light-overload (52 A) or 30 HP heavy-duty (44 A) at 460 V UL — the heavy-duty figure governs continuous pump duty; the light-overload rating handles the higher draw during startup or variable-flow cycles. Input voltage range is 440-480 V, 50/60 Hz, so it lands on standard North American 480 V distribution without a buck-boost transformer.
Enclosure and deployment
NEMA Type 1 enclosure (IP21) means it is rated for indoor use where falling dirt and dripping water are the main contaminants — typical for a pump house or irrigation control shed. The R6 frame size determines the mounting footprint and conduit entry layout; verify the existing panel cutout and bus bar spacing against the R6 drilling plan before ordering. No DIN-rail mounting on this frame class — it bolts directly to a back panel.
