At 0.37 kW (1.3 A rated, 2.6 A overload), the 6SL3520-1XE40-3AF0 is the smallest, most power-efficient drive in the entire SINAMICS G115D range. With just 33.7 W power loss dissipated by natural convection in the 380 × 156 × 129 mm FSA frame, it is the quietest and most maintenance-free drive on the conveyor line — no fan, no moving parts, no periodic service required.

What does the entry-level 0.37 kW G115D actually drive?

The 0.37 kW rating covers short straight-run roller conveyor zones — typically 1–3 meter sections driven by a 0.25–0.37 kW geared motor through a roller chain. In a large distribution center, these are the most numerous zones on the line: simple transport sections that move product between the more complex merge, divert, and accumulation zones. The G115D wall-mounted architecture means each zone gets its own drive, mounted at the motor, eliminating the long cable runs a centralized cabinet would require for hundreds of low-power zones. The 1XE configuration provides gland-type IP66 entry and C2 filtering as standard — the same environmental protection as a 7.5 kW FSC drive, just scaled to a 33.7 W power stage.

Key specifications

The drive operates from a 3 AC 380–480 V supply (45–66 Hz) with an output frequency range of 0–550 Hz. High-overload capability delivers 200% for 3 seconds and 150% for 57 seconds. The 350 Ω integrated braking resistor (10 W continuous) supports dynamic braking. Integrated PROFINET and Ethernet IP interfaces connect directly to SIMATIC controllers. The built-in C2 RFI filter meets EN 61800-3 Category C2 conducted emission limits.
