The ABB 3BBR50000417674 is the Frame Size R1 variant of the ACH580-01-012A-2 drive. Frame R1 determines the physical footprint — panel cutout, mounting hole pattern, and gland plate layout — for this drive rating. If you're replacing or specifying this order code, the frame is the dimension that locks the enclosure prep.
This part carries an active lifecycle stage, so it remains in ABB's current production portfolio.
