What it is
The ABB ACS355-03E-06A7-2 is an LV AC machinery drive module from the ACS355 line, built on frame R1 and rated for three-phase supply at 200-240 V across 47.5-63 Hz, which is the standard European light-industrial mains envelope. It ships as a panel-mount module in an IP20 open-type enclosure at 70 mm wide, 161 mm deep and 169 mm tall, so it drops into a standard cabinet cut-out on the ACS355 frame R1 footprint without special ventilation provisions beyond the open-type clearance rules.
Fit on the BOM line
IP20 and open-type NEMA rating means the drive expects a cabinet with the usual ingress protection — it is not a chassis for free-standing floor mounting without additional enclosure.
