The ABB 3ABD50000038994 is an ACH580-01-026A-4 wall-mounted HVAC drive rated for 11 kW normal duty (25 A output) on a 380–480 V three-phase supply. Heavy-duty use drops to 7.5 kW / 17 A; light-overload use holds at 11 kW / 23.8 A. Frame size R2, IP21, NEMA Type 1 enclosure. Efficiency class IE2.
Normal-duty 25 A output covers the continuous fan or pump load at 11 kW. Heavy-duty 17 A (7.5 kW) is the figure for constant-torque or high-starting-torque applications. Light-overload 23.8 A (11 kW) sits between the two. Frame R2 dictates the mounting footprint and gland-plate layout.
