What it is on the BOM line
The ABB ACS355-03E-07A5-2 is a member of the ACS355 variable-speed drive family, built in the R1 frame as a module intended for cabinet mounting inside an enclosure. It takes a 3-phase supply at 200-240 V across a 47.5-63 Hz input band, which is the figure that decides branch-circuit sizing, fusing class, and the rating of any line reactor placed upstream. The enclosure rating is IP20 open type, so the drive needs to live behind a panel or inside a cabinet that provides the rest of the ingress protection the installation demands — IP20 alone is not a cabinet-free rating.
Footprint and panel layout
At 70 mm wide, 169 mm tall, and 161 mm deep, the R1 module is a compact block that suits a side-by-side DIN-cabinet layout with adjacent terminal space for the power and control landings. Because the listing ships at 3 kg, a single installer can handle the swap on a planned outage; mounting hardware and clearances around the heat sink follow the standard ACS355 R1 pattern, not a custom bracket.
Sourcing posture
The standard quoted band on this code runs 1-10 working days, which means the part is specified into the BOM and built to order rather than pulled from a finished-goods shelf; the right move for a procurement buyer is to float an RFQ with the required quantity and any firmware or option-card suffix locked in before the order is released.
