The 6SL3210-1PH21-4AL0 is a SINAMICS G120 Power Module PM240-2 that converts 3-phase 500-690 VAC (+10%/-20%, 47-63 Hz) input into variable-frequency output for induction motors. It includes a built-in Class A EMC filter and a braking chopper, so you can skip external line filter and dynamic braking resistor modules in most installations. High Overload (HO) duty delivers 7.5 kW continuous with 200% torque for 3 seconds, 150% for 57 seconds, and 100% for 240 seconds — sized for pumps, fans, and conveyors that need short bursts of peak torque. Ambient limit is -20 to +50 °C in HO mode. Low Overload (LO) duty delivers 11 kW continuous with 150% for 3 seconds, 110% for 57 seconds, and 100% for 240 seconds — for constant-torque loads like compressors or mixers that don't need the headroom. Ambient limit drops to -20 to +40 °C in LO mode.
FSD frame size — physical dimensions 472 x 200 x 237 mm (HxWxD) — and IP20 protection means it mounts inside a ventilated enclosure, not in a washdown zone. The blocksize format shares a common footprint with other PM240-2 modules in the G120 family, simplifying cabinet layout. The Power Module ships without a Control Unit (CU) or operator panel — you order those separately. It is approved for CU firmware version V4.7 HF8, so match the CU firmware revision when commissioning to avoid parameter incompatibility. Packaging dimensions are 495 x 356 x 300 mm — allow for this in your logistics plan. The product class is C (manufactured/produced to order), meaning it is not held as a shelf stock item; lead time is confirmed at RFQ.
Active lifecycle and compliance documentation
RoHS compliant since 01-01-17. REACH Article 33 disclosure applies: Lead (CAS 7439-92-1) is present above 0.1% w/w in certain components — this is a standard declaration for industrial drives and does not restrict sale in EU markets. Export Control: AL N / ECCN 9N9999 — no special license required for most commercial destinations. Group code R220 and product group 9775 are the internal Siemens classification codes for this drive family.
