At 5.5 kW (13.2 A rated, 26.4 A overload), the 6SL3520-1XE45-5AB0 delivers the highest 1XE-series power rating in the fan-cooled FSC frame. The 1XE designation provides cable gland entry with integrated Category C2 filtering — combining the IP66 seal of gland termination with the conducted-emission compliance of a built-in filter in a single catalog code.

Gland entry vs. connector — which suits 5.5 kW conveyors?

At 5.5 kW, the power and signal cable diameters are substantial (typically 4–6 mm² power conductors). Gland entry accommodates these directly through the enclosure wall with a compression seal — no connector, no mating plug to stock, no contact corrosion risk in washdown environments. The tradeoff is longer installation time per drive compared to the connector (2XE) variant, but the IP66 rating holds without supplemental connector hoods. For food-and-beverage or outdoor conveyor lines where daily washdown is routine, gland entry with its full IP66 compression seal is the more robust choice.

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 FSC frame (425 × 180 × 169 mm) with integrated fan cooling handles 170.9 W power loss. 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 for industrial environments.
