What it is, and where it sits in a panel
The ABB ACS180-04N-03A7-1 is a low-voltage AC machinery drive module built on the R0 frame — a compact chassis sized for cabinet mounting rather than field exposure. Open-type construction with an IP20 degree of protection means the module is intended to live behind a panel door; it is not sealed against dust or water and should not be specified for unprotected environments.
Footprint and panel layout
The R0 module measures 70 mm wide by 209 mm tall and 143 mm deep, so the cabinet cutout and adjacent clearance are driven by those three numbers before any thermal derating is applied.
