The 6SL3520-2XB40-5AF0 sits at 0.55 kW in the SINAMICS G115D wall-mounted drive family — one step below the 0.75 kW entry in the same FSA frame. It delivers the same PROFINET and PROFIsafe connectivity in a package sized for lighter motor loads. This product carries an NCNR status.

What motor combinations does the 0.55 kW rating support?

The 0.55 kW output pairs with smaller SIMOGEAR 2KJ8 geared motor combinations — IE3 asynchronous for cost-sensitive applications or IE4 synchronous reluctance for higher efficiency at partial load. At 1.7 A HO rated current (3.4 A peak for 3-second overload), it covers light belt conveyors, small roller sections, and diverters where the driven load is modest and the motor frame is correspondingly compact.

Where does 0.55 kW fit in the G115D range?

The G115D wall-mounted range spans 0.37 kW to 7.5 kW across three frame sizes. At 0.55 kW, this drive sits in the lower third — intentionally sized for auxiliary and edge-of-line conveyor functions rather than main arterial sections. Choosing 0.55 kW over 0.75 kW saves energy cost on continuously running sections where the mechanical load does not justify the larger rating. Like all FSA-frame G115D drives, cooling is natural convection — no fan, no filter, no scheduled maintenance.
