Siemens 6SL3121-1TE15-0AA4 SINAMICS S120 5 A Single Motor Module
A 5 A single-axis booksize power module with external air cooling, retained by Siemens as a spare-part article.
Product Profile
Siemens 6SL3121-1TE15-0AA4 is a SINAMICS S120 Single Motor Module rated for a 5 A motor output. Its booksize power section uses external air cooling, accepts a 600 V DC nominal input and provides a 400 V three-phase output. Siemens identifies the article as a spare part and lists product cancellation effective 1 October 2021. The externally cooled 6SL3121 prefix is an essential distinction from the internally cooled 6SL3120 series.

Exact Product Identity
- Manufacturer: Siemens
- Model: 6SL3121-1TE15-0AA4
- Product Type: SINAMICS S120 externally air-cooled Single Motor Module
- Status: Cancelled spare part
Compatibility
- Preserve the complete 6SL3121-1TE15-0AA4 article when sourcing a like-for-like spare.
- Do not substitute the internally cooled 6SL3120-1TE15-0AA4 solely because the current rating matches.
- Verify external-air-cooling ducting, cabinet cutout and airflow separation.
- Check firmware, DRIVE-CLiQ topology, connectors, motor data and safety project.
- Because the article is cancelled, evaluate availability and any migration path before a planned shutdown.
Applications
- Existing S120 booksize installations using externally air-cooled 5 A power sections.
- Single-axis machine functions with the original AA4 generation.
- Lifecycle spares for cabinets that route power-section heat outside the electronics space.
- Maintenance programs recording exact cooling and hardware variants.
- Controlled like-for-like exchange with complete axis recommissioning.
