What it is and where it lands in the panel
The ABB ACS180-04N-06A9-1 is an LV AC machinery drive module in the ACS180 family, built on frame size R1. The package measures 70 mm wide, 220 mm tall, and 143 mm deep, with a 3-phase supply at 200 … 240 V across 47.5 … 63 Hz. Enclosure rating is open type / IP20, so it is a panel-build component — drop it inside a cabinet with the right clearance around it, not out by the motor. The mounting is module-style, meaning it sits on a backplate or DIN-style footprint consistent with the rest of the ACS180 R1 accessories.
Class context: where an LV AC machinery drive module earns its slot
Machinery drive modules in this class sit between the disconnect and the motor, taking fixed-frequency mains and delivering variable-speed control to conveyors, fans, pumps and small machine tools. The ACS180 R1 package targets the lower-horsepower end of that envelope — the kind of line where the cabinet, not the drive, is the thermal bottleneck, and IP20 open-type mounting is the convention.
