Drive package for irrigation duty
The ABB 3AUD0000003531 is an ACQ580 irrigation drive package built for 3-phase LV AC motor control on 440–480 V supplies. It delivers 40 hp in heavy-duty use (52 A) and 50 hp in light-overload use (65 A), so the heavy-duty figure governs continuous pump loads while the light-overload rating handles variable-torque applications like centrifugal pumps that rarely hit full current. The drive sits in an R6 frame with a NEMA Type 1 enclosure (IP21), meaning it's intended for indoor installation where drips and falling dirt are the main concern — typical for a pump panel in an irrigation shed. No washdown rating here; keep it out of direct spray.
