The Siemens 6SL3520-0XE41-1AB0 transitions the XE catalog designation from XE40 (0.37–0.75 kW) to XE41 (1.1–1.5 kW) within the SINAMICS G115D series. It delivers 1.1 kW at 3.1 A rated from the same FSA frame as the lower-power XE40 variants — the output stage rating doubles relative to 0.55 kW, within the identical 380×156×129 mm die-cast housing.

How does XE41 differ from XE40?

XE40 and XE41 are sequential catalog codes within the XE4x series, both occupying the FSA frame. XE40 covers 0.37–0.75 kW (parallel to XH00/XH20/1XA00); XE41 covers 1.1–1.5 kW (parallel to XH21/1XA01/1XA21). The transition from XE40 to XE41 reflects a higher-rated power stage — 3.1 A vs. 1.3–2.2 A rated — within the same physical enclosure. Both share natural convection cooling, IP65 sealing, and wall-mounted installation. The catalog code change at 1.1 kW marks the engineering reality that a more capable IGBT stage is needed, even though the external dimensions don't change.

The AB0 PROFINET interface integrates safety (PROFIsafe STO) and motion control on a single Ethernet connection. The 2-port switch supports daisy-chain line topology — each XE41 drive passes the PROFINET frame to the next — and MRP ring redundancy for fault-tolerant networks. EtherNet/IP coexistence means the same drive hardware can operate in Rockwell-dominated installations without gateway converters.
