The SINAMICS G115D is a distributed wall-mounted drive series for horizontal conveyor applications. The 6SL3520-1XE04-0AB0 delivers 4 kW at 10.2 A rated output (20.4 A overload) in the FSB frame with integrated fan cooling. This gland-type variant features an integral Category C2 line filter and uses a sealed cable gland for power entry — each drive receives its own dedicated feed.

Why does the G115D add fan cooling at 4 kW?

The FSB frame handles 2.2–3 kW with natural convection alone — no fans, no filters. At 4 kW, the thermal load exceeds passive cooling capacity. An integrated fan is added while maintaining the full IP65/66 enclosure integrity. The gland-type 1XE04 uses cable glands rather than quick-connect power connectors, suiting installations where daisy-chain power distribution is not required and each drive is individually fed.

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. Integrated PROFINET and Ethernet IP interfaces provide real-time communication with SIMATIC controllers. The built-in RFI filter meets Category C2 requirements.
