The 6SL3230-3YE36-1UF0 is the 37 kW G120X in the FSD frame with the 1UF0 suffix — 3C3 coating, unfiltered EMC, and the F-suffix alternate ordering channel. Rated 102 A at low overload (150% for 60 seconds), it is electrically identical to the 1UP0 variant: same power stage, same 3C3 environmental protection, same lack of integrated EMC filtering. The difference is the catalog channel — the F suffix provides an alternate procurement path for the same drive hardware.

The 3C3 coating protects the drive's internal electronics against corrosive gases and humidity — essential for wastewater treatment plants, chemical processing facilities, and coastal pump stations where standard-coated drives fail prematurely. The unfiltered configuration means EMC compliance must be achieved at the cabinet level, either through an external line filter or a shielded cable installation strategy. FSD frame footprint: 200 × 472 × 239 mm, approximately 22 kg.
