Drive selection note for this BOM line
The ABB 3AXD50000268481 is an ACQ580-01-114A-2 LV AC wall-mounted drive, sized for water and wastewater applications. It delivers 40 Hp light-overload output (114 A) and 30 Hp heavy-duty (30 A) on a 208–240 V three-phase supply, with an apparent power rating of 45 kV·A. The R5 frame carries an IP21 / NEMA Type 1 enclosure and is rated for a maximum ambient of 40 °C. Standby loss sits at 19 W, and efficiency meets IE2.
The light-overload current (114 A) is the figure that governs pump and fan duty — the typical water/wastewater load profile. If your motor is sized for constant-torque or high-starting-torque applications, the heavy-duty rating (30 A) is the binding limit. The 208–240 V input range covers common North American low-voltage three-phase supplies; confirm your line voltage falls within that band. The IP21 enclosure is suitable for indoor, dry panel installations; if the drive is mounted in a washdown area or outdoors, you'll need a higher IP rating.
