The ABB ACS530-01-12A6-4 (3ABD00039830) is a 5.5 kW general-purpose drive in a B1 frame, rated for 12.6 A normal-use output on a 380–480 V three-phase supply. It's built for pump, fan, and conveyor duty where IE2 efficiency and IP20 protection are enough — no washdown, no dust, just a clean cabinet install.
The 5.5 kW output at 12.6 A (normal use) is the continuous rating — size your motor to stay under that, and leave headroom for the 12 A light-overload current if you're cycling hard. The 16 W standby loss tells you what the drive pulls just sitting there with the run bit off; it's not a big heat load, but if you're packing drives tight in a panel, that 16 W per unit adds up. Input frequency tolerance from 47.5 to 63 Hz means it handles weak or generator-fed lines without tripping — useful if you're on a site with portable power or a grid that sags. The IE2 efficiency level keeps energy costs in check for constant-torque loads, though IE3 or IE5 would save more on long-run fan applications.
IP20 means it's for a clean, dry cabinet — no oil mist, no coolant splash. The open-type NEMA rating (no enclosure) confirms it's meant to be panel-mounted, not stand-alone. Ambient max 40 °C; derate if your cabinet runs hotter. The B1 frame is a compact footprint, but check the mounting centers against your backplate — it's not a universal hole pattern.
