Drive selection memo — water and wastewater duty
The ABB ACQ580-04 drive (order code 3AXD50000532858) is a LV AC wall-mounted drive purpose-built for water and wastewater applications. It delivers 700 Hp in heavy-duty (UL) use at 460 V, pulling 700 A continuous. For light-overload profiles — typical of pump and fan curves — it carries 807 A at the same voltage, giving headroom for variable-torque starts without oversizing the drive. Input is three-phase 440-480 V, 50/60 Hz, so it lands on standard North American 480 V distribution without a step-down transformer. The IP00 open-type enclosure means it mounts inside a panel or MCC — no onboard environmental seal, so the cabinet handles the dust and splash protection.
Integration notes — panel fit and wiring
Wall-mounted form factor, so it bolts to a backplate inside the enclosure. The 440-480 V input lands on a three-phase terminal block — torque per the nameplate label, not guessed. Heavy-duty current at 700 A means the input conductors and fusing must be sized for that continuous draw; the light-overload 807 A figure governs the branch-circuit protection rating if the pump curve is non-constant-torque. IP00 means no gasket seal on the drive chassis — the enclosure itself must provide the environmental rating. For water/wastewater sites that see washdown or humidity, spec a NEMA 12 or 4X cabinet around this drive.
