The Siemens 6SL32020AE203SA0 is a SINAMICS sinus filter designed for three-phase AC motor drives. It operates within a voltage range of 380 to 480 VAC and supports a nominal current rating of 3.5 A. The unit measures 110 x 75.5 x 200 mm and complies with RoHS standards. This component functions as an EMC/EMI line filter, utilizing threaded post connections (M5) to mitigate electromagnetic interference in industrial automation applications.
Verify the specific current rating of 3.5 A against your load requirements before procurement. Confirm that the physical dimensions of 110 x 75.5 x 200 mm fit your enclosure space. Ensure the M5 threaded post connection method matches your existing wiring infrastructure. Check for RoHS compliance if required by your project specifications.
Select this model when a compact sinus filter is needed for low-current applications up to 3.5 A. It is suitable for environments requiring strict EMC mitigation without large footprint components. Compare against higher current ratings if your motor load exceeds the specified limit. Consider the IP rating of the surrounding enclosure since this module itself may not be fully sealed.
This component belongs to the Siemens SINAMICS family of drive accessories. It serves as a complementary module to variable frequency drives, specifically addressing output quality and regulatory compliance issues related to electromagnetic emissions in industrial settings.
No direct public substitute part numbers are confirmed for this specific model. Verify compatibility with existing drive units before attempting any cross-brand replacements.
