The ABB 3AXD50000760947 is the ACQ580-01-059A-2, a wall-mounted LV AC drive built for water and wastewater applications. It runs on a 208-240 V three-phase supply at 50/60 Hz and delivers 20 Hp with 59 A in light-overload use, or 15 Hp at 15 A for heavy-duty cycles. The R3 frame keeps the footprint manageable for panel layouts where NEMA 1 and IP21 are specified.
Duty ratings and real-world fit
The light-overload rating of 59 A is the number to size by for pump and fan profiles — it gives you headroom for variable-torque starts without oversizing the drive. Both are UL-listed, so the drive lands cleanly in a UL 508A panel without a derating fight.
NEMA 1 enclosure with IP21 protection means it's suitable for indoor, non-condensing environments — typical for a pump room or treatment gallery. Wall-mount the R3 frame with clearance above and below for airflow; the IP21 rating doesn't tolerate washdown, so keep it out of the spray zone.
