At 3 kW (7.7 A rated, 15.4 A overload), the 6SL3520-1XE43-0AB0 combines the 1XE series gland-type entry and integrated C2 filter with the convection-cooled FSB platform. For conveyor installations in food production, outdoor logistics, or wet processing areas, the gland entry's IP66 compression seal provides a more robust environmental barrier than connector-type (IP65) alternatives — no connector contact corrosion, no supplemental hood required.

Where does the gland+C2 combination matter most at 3 kW?

The 3 kW power level is the most commonly deployed G115D rating in distribution-center conveyor networks — hundreds of identical units across miles of conveyor line. In this environment, two things dominate total cost of ownership: cleaning downtime and RFI-related commissioning delays. The IP66 gland seal eliminates connector corrosion as a failure mode when conveyors are washed down. The integrated C2 filter eliminates the need to source, mount, and wire a separate external filter per drive — multiply that by 200 drives and the saved enclosure space, BOM line items, and wiring hours are substantial. The 425 × 180 × 134 mm convection-cooled envelope runs silently with no fan — a meaningful consideration when drives are mounted at operator-accessible height along the conveyor frame.

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 C2 RFI filter meets EN 61800-3 Category C2 conducted emission limits for industrial environments.
