The 6SL3520-1XD00-5AB0 brings the 0.55 kW power step to the 1XD D-connector SINAMICS G115D family — 1.7 A HO (3.4 A LO) in the FSA compact frame (380 × 156 × 129 mm, ~4.7 kg) with natural convection cooling. 0.55 kW is the lowest 3-phase G115D wall-mounted power rating — it extends the drive downward from 0.75 kW for the lightest conveyor zones, small fans, and low-power auxiliary drives. AB0 provides Standard I/O terminal control at 380–480 V three-phase. Compatible with IE2/IE3/IE4 motors across 0–550 Hz, IP65 sealed.

Which applications suit 0.55 kW in the G115D range?

0.55 kW at 1.7 A HO serves the lightest motor loads in a distributed automation system: individual roller sections on zero-pressure-accumulation conveyors, small extraction fans, compact pumps, and auxiliary positioning drives. It carries the same IP65 machine-mount rating and 0–550 Hz output as the higher-power G115D variants — the lower current rating is the only distinction. If the application needs fieldbus communication, the AF0 (PROFINET) variant at 1XD00-5AF0 provides PROFINET IO with PROFIsafe in the same 0.55 kW FSA package.

How does 0.55 kW compare to 0.75 kW in the same FSA frame?

Both 0.55 kW (1.7 A HO) and 0.75 kW (2.2 A HO) share the identical FSA enclosure (380 × 156 × 129 mm) and natural convection cooling — the difference is the IGBT power stage rating. The 0.55 kW variant provides 1.7 A continuous rated current vs 2.2 A at 0.75 kW. For applications where 0.75 kW would be oversized, 0.55 kW offers a lower-cost entry point with the same mechanical mounting, same connector ecosystem, and same IP65 protection.
