The ABB 3ABD00049823 is an ACQ531-01-09A4-4+J400 drive rated for 4 kW output at 9.4 A input current, built on frame size R0. It carries an IE2 efficiency classification, which places it in the standard-efficiency band for motor drives — not premium, but adequate for fixed-speed pump and fan applications where the duty cycle doesn't justify the IE3 or IE4 upcharge.
Frame size R0 is the smallest mechanical envelope in the ACQ531 family. That keeps panel space tight — useful for retrofit into existing cabinets where gland-plate real estate is already allocated. The 9.4 A rating at 400 V three-phase covers a standard 4 kW induction motor; watch the cable sizing for the input side if the run exceeds 50 m.
