Drive Identification and Sourcing
The ABB 3BBR50000038939P01 is the order code for an ACS580-01-04A1-4 general-purpose drive, built on the Frame Size R1 platform. This is the current-production variant, confirmed active per the lifecycle stage.
Frame Size and Physical Fit
Frame Size R1 defines the mounting footprint, gland-plate layout, and heat-sink profile. For panel builders, this frame determines the DIN-rail or backplate cutout and the minimum clearance for airflow. Verify the existing enclosure's gland plate accommodates the R1 cable entry pattern before committing the BOM line.
