The ABB 3ABD00057907 is an LV AC machinery drive module, rated for 1.5 kW normal-use output at 4.0 A on a 380–480 V three-phase supply. The heavy-duty rating drops to 1.1 kW / 3.3 A for constant-torque loads.
Three output ratings are listed: normal use (Pn 1.5 kW, In 4.0 A), heavy-duty (PhD 1.1 kW, IhD 3.3 A), and light-overload (PlD 1.5 kW, IlD 3.8 A). For a pump or fan with variable torque, the normal-use figure applies. For a positive-displacement pump or a crusher, size to the heavy-duty current. The light-overload rating sits between the two — useful when the load profile has occasional spikes but stays below the normal-use ceiling.
That means you can spec this into a BOM without worrying about a sudden obsolescence-driven requalification.
