The ABB 3AUD0000003533 is a LV AC 3R irrigation drive package from the ACQ580 series, rated for 75 Hp light-overload use (96 A) and 60 Hp heavy-duty use (77 A) at 460 V, on a 3-phase 440–480 V input at 50/60 Hz. The R8 frame size and NEMA Type 1 enclosure (IP21) suit it for indoor pump-panel mounting in irrigation and water-handling applications — the NEMA 1 rating means it's drip-proof but not washdown-rated, so keep it out of direct spray.
UL ratings and duty selection
Two UL output ratings let you size the drive to the load profile. Light-overload (75 Hp, 96 A) fits variable-torque loads like centrifugal pumps where peak current stays brief. Heavy-duty (60 Hp, 77 A) covers constant-torque or high-starting-torque applications — conveyors, screw feeders, positive-displacement pumps. Pick the duty class that matches your motor's nameplate FLA and the driven load's starting profile; the drive's internal overload protection is set accordingly.
