The Siemens 6SL3211-1NE21-8AL0 is a SINAMICS G120 Power Module PM230 rated for 7.5 kW at low overload (150% for 3 s, 110% for 57 s, 100% continuous) on 380-480 VAC three-phase, 47-63 Hz input. The integrated Class A filter handles conducted emissions for European industrial mains without an external EMC filter. No Control Unit is included — this is the power stage only, compatible with CU240B/E-2 and CU230P-2 control units running firmware V4.4 or higher. The 7.5 kW low-overload rating means this module drives a constant-torque load like a conveyor or positive-displacement pump at full rated current continuously, with 150% headroom for 3 seconds during startup or jam conditions. For variable-torque loads (fans, centrifugal pumps), the same hardware can typically support a higher power rating — but the low-overload curve is the conservative spec for sizing. The 345 x 154 x 171 mm (HxWxD) FSB frame size fits the standard G120 power stack footprint; plan for adequate clearance above and below for airflow, and verify that the control unit slot is populated before commissioning.
No official successor has been published for the 6SL3211-1NE21-8AL0. The PM230 platform remains current in the G120 family. For a BOM freeze or long-term supply agreement, we can quote volume pricing and lead time on request.
Integration notes
No safety functions are supported on the PM230 — the note says 'PM230 supported no safety'. If the application requires Safe Torque Off or Safe Stop, step up to the PM240-2 power module variant (different order code).
