The Siemens 6SL3210-1NE21-3UL0 is a SINAMICS G120 Power Module PM230 in an unfiltered IP20 enclosure, sized for a 5.5 kW low-overload motor load on 380-480 V three-phase supply. It ships without a Control Unit or operator panel — you pair it with a CU240B/E-2 or CU230P-2 running firmware V4.4 or higher. The PM230 variant is optimized for pump and fan applications; note it does not support safety functions.
Load profile and derating
Low-overload rating delivers 5.5 kW continuous with 150 % overload for 3 seconds, 110 % for 57 seconds, and 100 % for 240 seconds — typical for centrifugal loads where peak torque is brief. The 380-480 V input accepts +10/-10 % tolerance at 47-63 Hz, covering most global 50/60 Hz mains.
