Drive package for irrigation duty
The ABB 3AUD0000003532 is an ACQ580 series LV AC drive package configured for 3R irrigation applications. It carries UL ratings for both light-overload (60 Hp, 77 A) and heavy-duty (50 Hp, 65 A) use at 460 V, 3-phase, 50/60 Hz. The NEMA Type 1 enclosure with IP21 protection suits indoor or sheltered outdoor pump houses — not direct washdown, but fine for a dry irrigation panel.
The 77 A light-overload rating at 460 V governs the nominal pump motor sizing — that's the continuous current the drive can deliver without derating. The 65 A heavy-duty rating applies when the load profile demands higher peak torque or a wider constant-torque speed range; a 50 Hp irrigation pump running at variable flow would typically land here. Frame size R6 indicates the physical footprint and bus-bar layout — confirm the gland-plate clearance and mounting hole pattern against the existing panel cutout before ordering.
