What it is and where it lands in the panel
The ABB ACS180-04N-033A-4 is an LV AC machinery drive module built around the ACS180 family, sized to the R3 frame at 170 mm wide, 205 mm tall, and 174 mm deep so it drops into a standard cabinet cutout next to its R3 neighbours. The line-side feed is 3-phase 380 to 480 V at 47.5 to 63 Hz. Enclosure is IP20 open type, meaning the chassis is finger-safe from the front but not sealed against dust or washdown — the drive has to live inside the cabinet with the line filter and braking components arranged around it.
Mounting and handling notes
Module mounting keeps the R3 footprint on a 170 x 205 mm face, so back-to-back panel layouts stack cleanly with adjacent R3 units and leave the 174 mm depth for cable bend radius behind the drive.
