The 6SL3520-1XE00-5AB0 is the Standard I/O variant at 0.55 kW in the newly-discovered 1XE00 code — the "1X" prefix XE series SINAMICS G115D for SIMATIC control systems. 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. AB0 joins AF0 (PROFINET) at 1XE00-5 — two of the three expected communication variants now confirmed at this power step in the new 1XE code system. Operates at 380–480 V three-phase, compatible with IE2/IE3/IE4 motors across 0–550 Hz, IP65 sealed.

1XE — the fourteenth code system and what it completes

With 1XE, every major G115D catalog family now exists in both "0X" and "1X" prefix versions: 0XE/1XE (general-purpose), 0XB/1XB (B-connector), 0XC/1XC (C-connector), 0XD/1XD (D-connector). The XE family is the last to gain its "1X" counterpart — and fittingly, it debuts at the entry-level FSA power range (0.55–0.75 kW), exactly where the broadest customer base will encounter it. The 1XE series is expected to eventually span the full 0.37–7.5 kW G115D range, mirroring 0XE's coverage across both XE4x and XE0x sub-series.
