The ABB 3ABD00045426-D is a wall-mounted LV AC drive for water and wastewater. It delivers 75 kW normal-duty output at 145 A from a 380–480 V three-phase supply, with a heavy-duty rating of 55 kW and 105 A.
Normal-use output is 75 kW at 145 A; light-overload use also lands at 75 kW but draws 138 A, so the 145 A normal figure is the one to size cable and protection for. Heavy-duty use drops to 55 kW and 105 A — that's the rating for constant-torque loads like positive-displacement pumps or screw feeders. Input voltage covers 380–480 V at 47.5–63 Hz. Efficiency class IE2 meets the base EU motor-drive efficiency level for this power band. The enclosure is NEMA Type 1 with IP21 ingress protection — drip-proof, indoor installation only. Frame size R6 tells you the physical footprint for panel layout and mounting bracket spacing.
