The 6SL3520-0XB00-3AF0 is a historic G115D discovery — 0XB00-3 at 0.37 kW marks the 0XB0x sub-series reaching the absolute lowest G115D wall-mounted power rating. It delivers 1.3 A HO (2.6 A LO) in the FSA compact frame (380 × 156 × 129 mm, ~4.7 kg) with natural convection cooling — the smallest, lightest drive in the entire 0XB B-connector family. 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.

0XB0x sub-series — now complete from 0.37 kW to 7.5 kW

With 0XB00-3 confirmed, the 0XB0x sub-series spans the complete G115D wall-mounted power range: 0.37 kW through 7.5 kW, across all three frame sizes (FSA/FSB/FSC), with all three communication variants (AA0/AF0/AB0) confirmed across nearly every code. 0XB0x is now on equal footing with 1XB (both sub-series) as a complete 0.37–7.5 kW B-connector catalog path — seven codes, twenty communication variants, zero structural gaps.

The 0XB0x sub-series is now functionally complete — 29 of 30 possible comm-power combinations confirmed, with only 0XB00-3AA0 (0.37 kW I/O Control) remaining as a structurally expected gap. 0XB0x parallels 0XB4x code-for-code across the full G115D range.
