The 6SL3520-1XL03-0AF0 is the 3 kW, FSB-frame G115D in the 1XL variant — the mid-power FSB model rated at 7.7 A continuous with 15.4 A peak (200% for 3 seconds). The AF suffix equips it with PROFINET communication for SIMATIC-controlled distributed automation. In the 1XL variant, the FSB enclosure measures 425 × 240 × 134 mm on a 3-phase supply — 35 mm shallower than the 4 kW version, reflecting the lower cooling demand at 3 kW while retaining the same wall-mount footprint.

IP65 (connectors) / IP66 (cable glands) / UL Type 4X Indoor protection supports washdown and dusty production environments without a control cabinet. Standard G115D features include an integrated C2 EMC filter, internal braking resistor, STO SIL 2 via Profisafe, and SAM web-server commissioning. IE2/IE3 asynchronous and IE4 synchronous reluctance motors are supported with V/f or vector control from 0–550 Hz.
