The Siemens 6SL3210-1NE21-3AL0 is a SINAMICS G120 Power Module PM230 with an integrated Class A EMC filter, sized for a 5.5 kW low-overload motor load on 380-480 V three-phase mains. It delivers 150% overload for 3 seconds, 110% for 57 seconds, and 100% continuously over 240 seconds — a duty curve that handles pump, fan, and conveyor starts without oversizing the drive frame.
Control unit and firmware requirements
This power module is a drive stage only — it requires a separate SINAMICS G120 Control Unit. Compatible types are CU240B/E-2 and CU230P-2, running firmware V4.4 or higher. The PM230 does not support safety functions, so if your application needs STO or SS1, pick the PM240 variant instead.
