The 6SL3230-3YE20-1UF0 is a 4 kW SINAMICS G120X general-purpose converter with DC link terminals, unfiltered, designated by the F-suffix alternative ordering channel. Rated at 10.5 A LO in the FSB frame, it steps down from the 5.5 kW 3YE22 variants in power while maintaining DC link access for du/dt filter connection on longer motor cable runs.

4 kW with DC Terminals — The Entry Point for Filtered Motor Protection

The 3YE20 power code delivers 4 kW at quadratic load (3 kW at linear load) with 10.5 A LO rated output from a 380–480 V 3 AC supply. The 1UF0 variant adds DC link terminals for du/dt filter connection — protecting motor windings on long cable runs — and uses unfiltered EMC for installations with system-level filtering. Electrically identical to the 1UP0 (P-suffix standard catalog) — the F/P distinction is purely commercial. The FSB frame (100 × 275 × 209 mm, IP20) houses the full G120X control platform: V/f square-law and V/f ECO for energy-optimized pump and fan control, 110%/60s LO overload, PROFINET/EtherNet/IP/USS/Modbus RTU/BACnet MS/TP, and integrated STO via F-DI or PROFIsafe.
