Drive selection memo — ACQ580-01, 30 kW
The ABB 3ABD00046036-D is an ACQ580-01 wall-mounted drive rated 30 kW normal use (62 A) on 380-500 V three-phase input. The R4 frame carries the IP21 sheet-steel enclosure for indoor panel or wall mounting. Heavy-duty duty cycle drops to 22 kW / 44.6 A — sized for pump and fan loads in water and wastewater service where the overload profile is well below the normal-use curve.
The heavy-duty rating (22 kW, 44.6 A) applies when the drive must deliver 150% overload for 60 seconds, typical for screw pumps, positive-displacement blowers, or lift stations with high breakaway torque. Light-overload use (30 kW, 58 A) sits between the two — a lower current limit than normal use despite the same power figure, meaning the drive's thermal capacity is the constraint, not the motor rating.
The R4 frame is sized for the 30 kW output stage — gland plate entry on the bottom, cable clearance for 3-phase power and control wiring. No DIN-rail option; the drive bolts directly to a backplate or wall bracket.
