Drive selection note for a 1.1 kW HVAC fan or pump
The ABB 3ABD50000038999 is an ACH580-01 wall-mounted drive rated 1.1 kW normal use, 3.3 A output, on a 380-500 VAC three-phase supply. Frame R1, IP55, Type 12 enclosure — sized for standalone mounting in a non-conditioned space. Heavy-duty rating is 0.75 kW / 2.6 A, so if the motor is a constant-torque load (conveyor, positive-displacement pump), size against the HD column. Light-overload rating at 3.1 A sits between the two.
