The 3ABD00048738-D is an ABB ACQ580-01 wall-mounted LV AC drive, Frame R4, rated for 37 kW normal use (73 A output) on 380-480 V three-phase supply. Heavy-duty duty cycle drops to 30 kW (61 A), light-overload holds at 37 kW (68 A). The IP21 enclosure with NEMA Type 1 suits indoor panel or machine mounting; the IE2 efficiency class meets current minimum standards for most water and wastewater applications.
The 73 A normal-use output current is the figure to match against the motor full-load amps. Heavy-duty 61 A governs when the drive must deliver 150 % overload for 60 seconds — typical for crushers or centrifugal pumps with high breakaway torque. The 380-480 V input range covers 400 V and 480 V nominal grids; the 47.5-63 Hz frequency window accommodates 50 Hz and 60 Hz supplies without derating.
