Irrigation drive package in frame R4
The ABB 3AUD0000003515 is an ACQ580 series LV AC drive package purpose-built for irrigation duty, delivering 60 Hp at 77 A under light-overload conditions or 50 Hp at 65 A under heavy-duty use at 460 V. Frame size R4 keeps the footprint manageable for pump panels, and the NEMA Type 1 enclosure with IP21 protection is suited for indoor or sheltered outdoor installation — not direct spray, but fine for a pump house or ventilated cabinet. Input voltage range is 440 to 480 V three-phase at 50/60 Hz, covering standard North American and 50 Hz global supply.
The light-overload rating (60 Hp, 77 A) is the one you size for variable-torque loads like centrifugal pumps — the drive carries 110% current for 60 seconds, enough for starting a pump against a closed discharge valve. The heavy-duty rating (50 Hp, 65 A) applies for constant-torque loads or applications requiring 150% overload for 60 seconds, such as positive-displacement pumps or screw feeders. Pick the duty class that matches your pump curve and starting regime; the 77 A LO figure gives headroom for standard irrigation pump starts without oversizing the drive.
