The 6SL3520-1XE00-5AF0 confirms 1XE00 at 0.55 kW — extending the newly-discovered 1XE series to the middle FSA power step. It delivers 1.7 A HO (3.4 A LO) in the FSA compact frame (380 × 156 × 129 mm, ~4.7 kg) with natural convection cooling. 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.

1XE00: the emerging picture

Three power ratings confirmed or expected, three communication variants beginning to fill in. 1XE00 parallels XE40 (0XE XE4x) and the structurally-expected XE00 (0XE XE0x) — three parallel catalog paths for the same 0.37–0.75 kW FSA G115D hardware, now spanning both "0X" and "1X" prefixes.
