The G120X FSB UF targets pump, fan, and compressor applications requiring a compact chassis-mount inverter in the 4 kW class. The 23.7 A output rating aligns with typical three-phase motor sizes near 2.2–3 kW at 200–240 V; confirm motor nameplate current does not approach the inverter limit under continuous load.

Why similar: All listed units share the SINAMICS G120X series, IP20 box encapsulation, chassis-mount form factor, and AC motor compatibility. Differences among the first six part numbers appear in the suffix field only and do not alter the electrical ratings shown in the catalog record. Units such as 6SL32301YC221UP0 and 6SL32301YC261UP0 share the same platform and input voltage range but target higher power classes (5.5 kW and 11 kW respectively) with proportionally higher output current ratings.
