The ABB ACS355-01E-02A4-2 is the single-phase 200 … 240 V member of the ACS355 micro-drive family, packaged as an R1-frame module for cabinet building. The IP20 open-type enclosure keeps it an inside-the-cabinet device — it expects a panel behind it, not a wall mount on its own. On the I/O side it carries 2 analog inputs, 1 analog output, 5 digital inputs and 1 digital output, with Modbus as the listed communication protocol — a tight slice that fits small standalone machines rather than a multi-axis cell. The unit is 70 mm wide, 239 mm tall and 161 mm deep on the R1 footprint, so it drops into the same DIN-rail/cabinet geometry as other R1 ACS355 drives. At 1.7 kg it is a single-handler on the panel — well inside anything that needs a rigging plan.
Panel layout and handling
The 70 × 239 × 161 mm R1 outline and IP20 open-type rating mean the drive lives inside the cabinet, mounted per the module-for-cabinet-building intent — leave clearance above and below for the cooling airflow path that the ACS355 family is known to require. The 3 kg shipping weight reflects packaging rather than the 1.7 kg bare unit, so plan the bench and the unboxing for one person.
Sourcing posture
The part is offered against an RFQ rather than off-the-shelf. Specify it into the BOM as the active ACS355 single-phase variant and let the RFQ carry the production confirmation through the channel.
