ABB 3AXD50000269006 is a wall-mount drive for water and wastewater duty. It runs on 525 to 600 V three-phase input, 50/60 Hz, and delivers 100 Hp with 99 A under light-overload profile, or 75 Hp at 75 A for heavy-duty cycles. Frame size R7, IP55 enclosure, NEMA Type 12.
The light-overload rating (100 Hp, 99 A) is the one you spec for variable-torque centrifugal pumps and fans — the drive runs continuously at that current without derating. Heavy-duty (75 Hp, 75 A) covers constant-torque loads like screw compressors or positive-displacement pumps. If your BOM calls for 575 V class and 100 Hp motor, this is the UL-listed match. IP55 and NEMA Type 12 mean the drive handles dust, hose-down, and condensation common in water treatment plants. Wall-mounting and R7 frame keep the footprint predictable for retrofit into an existing panel cutout.
