The ABB 3ABD00057962 is a low-voltage AC machinery drive module, rated 1.1 kW normal-use output at 3.3 A, with a heavy-duty rating of 0.75 kW at 2.6 A. It operates on 380–480 V three-phase input, 47.5 to 63 Hz, and carries an IE2 efficiency class.
Normal-use rating (1.1 kW, 3.3 A) is the continuous output for typical variable-torque applications like fans and pumps. Heavy-duty rating (0.75 kW, 2.6 A) is the figure to use for constant-torque loads — conveyors, extruders, or any application requiring full torque at low speed. Light-overload rating sits at 1.1 kW, 3.1 A, which is essentially the normal-duty current with a slightly lower continuous ceiling; treat it as a derated normal-use curve for applications with moderate overload cycles. Match your motor nameplate to the duty class that reflects your actual load profile — the heavy-duty number is the one that governs if you have a demanding mechanical cycle.
