The ABB 3AUD0000003536 is an ACQ580 irrigation drive package — a 3-phase LV AC variable-frequency drive in a NEMA Type 1 enclosure, rated IP21. It is built for pump and irrigation duty, with UL-listed output ratings of 150 Hp (180 A) under light-overload use and 125 Hp (156 A) under heavy-duty use at 460 V. Frame size R8 means it occupies the larger footprint in the ACQ580 family, sized for the 180 A continuous current.
Input voltage range is 440–480 V at 50/60 Hz. The light-overload rating (180 A, 150 Hp) covers centrifugal pumps running at or below nameplate — typical for irrigation where the load profile is steady, not cyclic. The heavy-duty rating (156 A, 125 Hp) applies when the drive must handle 150% overload for 60 seconds, such as for a clogged pump or startup against a closed valve.
Deployment context
The NEMA Type 1 enclosure suits indoor or sheltered outdoor installations — not for direct washdown or rain exposure. Frame R8 drives typically mount on a floor or wall bracket; plan for adequate clearance around the heatsink fins for convective cooling at 180 A continuous.
