The SINAMICS G115D is a distributed wall-mounted drive series for horizontal conveyor applications. The 6SL3520-1XE03-0AA0 delivers 3 kW at 7.7 A rated output (15.4 A overload) in the FSB frame with natural convection cooling — the highest power rating achievable without a fan in the G115D wall-mounted range. This gland-type variant features an integral Category C2 line filter and sealed cable gland power entry.

What makes the 3 kW FSB fanless significant?

Three kilowatts is the passive cooling ceiling for the G115D platform. Above this, the FSB frame requires an integrated fan (4 kW) or steps up to the FSC frame (5.5–7.5 kW). For conveyor zones operating within this power band, fanless operation means zero fan maintenance, no airflow path to keep clear, and silent running — all while maintaining IP65/66 protection. The gland-type 1XE03 uses individual cable gland feeds rather than daisy-chain connectors, simplifying installations with dedicated power drops.

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 connect directly to SIMATIC controllers. The built-in RFI filter meets Category C2 requirements.
