The 6SL3230-3YE30-1UB0 is the B-suffix variant of the 18.5 kW unfiltered G120X with DC link terminals and a built-in IOP-2 operator panel. It delivers 51.3 A rated output at 380–480 V 3 AC in the FSD frame (200 × 472 × 239 mm, IP20) for cabinet-mounted pump and fan applications.

IOP-2 on the 18.5 kW unfiltered platform

The B-suffix adds an IOP-2 intelligent operator panel for local commissioning, parameter adjustment, and diagnostics without external software. At 18.5 kW — the entry point to the FSD frame class — the IOP-2 is particularly valuable during initial setup, providing a guided startup wizard and plain-text parameter descriptions. The DC link terminals support du/dt filter connection for motor winding protection on long cable runs. The unfiltered EMC status requires an external filter when Category C2 compliance is needed.
