The 6SL3520-2XB03-0AA0 is the minimal-I/O configuration of the 3 kW FSB fanless G115D B-connector drive — a silent, slim (134 mm deep), natural-convection drive for conveyor sections that just need to run. At 7.7 A HO, it covers accumulation zones, transfer belts, and incline sections up to 3 kW without a fan, without a fieldbus, and without unused I/O terminals.

When does this simplest configuration fit best?

Choose AA0 for conveyor sections with one or two hardwired signals — run/stop and an e-stop — in noise-sensitive locations. The fanless FSB enclosure (425 × 180 × 134 mm) installs directly on the conveyor frame, IP65/IP66 sealed against washdown and dust. If the same section carries more sensors, step to AB0 for expanded I/O; if the line runs PROFINET with PROFIsafe, the AF0 variant integrates safety and control over the network.
