The ABB ACQ531-01-106A-4+0J404 (3ABD00049856) is a 55 kW, 106 A variable frequency drive in an R5 frame, built for 380–480 V three-phase supply. IP20, wall-mounted, and rated IE2 efficiency — this is the normal-duty variant (same 55 kW rating under light overload, with output current at 100 A). Frequency range covers 47.5 to 63 Hz, so it handles 50 Hz or 60 Hz line without a derate.
What fits where
R5 frame is wall-mount only — no cabinet slide rails. The 380–480 V input range covers standard 400 V and 480 V industrial supplies; the 47.5–63 Hz input frequency lets it run on 50 Hz or 60 Hz mains without a line reactor swap. The 106 A normal-duty output drives a 55 kW motor; if the load profile is light (variable torque, not constant torque at full rating), the 100 A light-overload figure still supports the same 55 kW motor.
