The 6SL3520-0XB01-5AF0 marks a major milestone for the 0XB0x sub-series — 0XB01 is the first 0XB0x code in the FSA compact frame (380 × 156 × 129 mm, ~4.7 kg), extending the sub-series downward from FSB into FSA territory. It delivers 4.1 A HO (8.2 A LO) at 1.5 kW with natural convection cooling — the highest FSA power rating before the transition to FSB at 2.2 kW. AF0 provides PROFINET IO with PROFIsafe, EtherNet/IP, and an integrated 2-port switch. Designated for SIMATIC control systems. Operates at 380–480 V three-phase, compatible with IE2/IE3/IE4 motors across 0–550 Hz, IP65 sealed.

0XB01: dual-power FSA code in the 0XB0x sub-series

Like XH21, 1XA01, 1XA21, 1XA61, XE41, and XE01 in their respective families, 0XB01 covers two FSA power ratings: 1.1 kW (0XB01-1, 3.1 A HO) and 1.5 kW (0XB01-5, 4.1 A HO). Both share the identical FSA enclosure — the designation difference reflects the IGBT power stage rating, not a physical frame change. 0XB01 parallels 0XB41 in the 0XB4x sub-series — same 1.1–1.5 kW FSA B-connector hardware, different catalog sub-series path within the 0XB family. For the engineer, 0XB01 provides the highest FSA power available in the 0XB0x catalog path.
