Drive package for irrigation duty
The ABB 3AUD0000003508 is an ACQ580-series LV AC drive package built for 3-phase irrigation pump control. Input voltage range is 208 to 240 V, and the UL ratings tell the real story: 40 Hp / 114 A in light-overload service (typical for centrifugal pumps running steady), or 30 Hp / 88 A under heavy-duty use (higher torque demand, repeated starts). Frame size R5, so it's a compact panel-mount package for the power class.
Light-overload 40 Hp at 460 V matches a standard 40 Hp pump motor running a steady load curve — no need to oversize. The heavy-duty 30 Hp rating covers applications where the drive sees higher peak torque or frequent acceleration cycles, like a well pump cycling on pressure. The 114 A light-duty output current is the number to match against the motor FLA; if the motor draws 110 A at full load, this drive has headroom. The 88 A heavy-duty figure governs continuous rating for tougher profiles. IP21 and NEMA Type 1 enclosure means it's suitable for indoor installation in a clean, dry environment — a pump house or control room, not a washdown zone.
