Drive selection memo — ABB ACQ580-01-062A-4+X1666+N7560
The ABB ACQ580-01-062A-4+X1666+N7560 (3ABD00048737-D) is a wall-mounted LV AC drive, frame size R4, built for water and wastewater duty. Normal-duty output is 30 kW at 62 A; for heavy-duty applications like aeration blowers or sludge pumps, it carries 22 kW at 45 A. Input voltage spans 380–480 V three-phase at 47.5–63 Hz, so it handles 50 Hz and 60 Hz plants without a re-rate. The IP21 enclosure and NEMA Type 1 rating mean it's suited for indoor, dry environments — pump rooms, treatment galleries, or MCC buildings where occasional drips or dust might be present but not washdown. Wall-mounting saves floor space in tight retrofit panels.
