The 6SL3520-0XB02-2AF0 is the debut of 0XB02 — the 0XB0x sub-series B-connector SINAMICS G115D at 2.2 kW FSB fanless, filling the critical FSA-to-FSB transition power in the 0XB0x catalog path. It delivers 5.9 A HO (11.8 A LO) in the fanless FSB enclosure (425 × 180 × 134 mm, 7.12 kg) with natural convection cooling. 2.2 kW is where the G115D moves from the compact FSA frame to the larger FSB — natural convection in FSA cannot dissipate the heat above 1.5 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.

0XB02: the FSA-to-FSB bridge in the 0XB0x sub-series

0XB02 at 2.2 kW is the only FSB fanless code between 0XB01 (1.1–1.5 kW FSA) and 0XB03 (3 kW FSB fanless). It is the entry point to the larger FSB enclosure in the 0XB0x path — the first 0XB0x code that requires the 425 × 180 × 134 mm frame. In the parallel 0XB4x sub-series, 0XB42 fills this same position. For the engineer, 0XB02 provides B-connector convenience at the most compact FSB power rating — the smallest drive that needs the larger frame, making it the lightest FSB option for medium-power distributed zones.
