The ABB 3ABD00057777 is an ACS380-series LV AC machinery drive module rated for 22 kW normal-duty output at 50.0 A, with heavy-duty output at 22.0 kW and 45.0 A. It accepts 380-480 V three-phase input across 47.5 to 63 Hz and is housed in frame size R4 with IP20 protection. Efficiency class IE2 is standard for this module.
Key Ratings in Context
The normal-duty current of 50.0 A at 22 kW sets the continuous rating for typical variable-torque loads such as fans and pumps. Heavy-duty output at 45.0 A matches constant-torque applications like conveyors or extruders where overload capacity is required. The 380-480 V input range covers standard 400 V and 480 V industrial mains, and the 47.5-63 Hz frequency acceptance accommodates both 50 Hz and 60 Hz grids without derating.
The open-type NEMA enclosure rating aligns with this — the drive requires external overcurrent protection and should be mounted on a flat, non-flammable surface with clearance for airflow per the installation manual.
