Siemens 6SL3121-1TE26-0AA0 SINAMICS S120 60 A Single Motor Module
The first-generation 60 A external-air-cooled module is an end-of-lifecycle spare with AA3 identified as its successor.
Product Overview
Siemens 6SL3121-1TE26-0AA0 is a SINAMICS S120 Single Motor Module for one motor axis. It uses the 600 V DC input class, supplies a 400 V three-phase output rated at 60 A and relies on external air cooling. Siemens marks this AA0 generation at the end of its product lifecycle and identifies 6SL3121-1TE26-0AA3 as the successor product.
Performance
- Provides a 60 A three-phase motor output for one drive axis.
- Draws power from the SINAMICS common DC-link architecture.
- Uses external air cooling for the module thermal path.
- Connects to the coordinated drive system through the included DRIVE-CLiQ cable.
- Maintains the TE26 60 A power-class identity within the booksize range.
- Supports engineered replacement planning through the documented AA3 successor relationship.

FAQ
What is the rated output current of the AA0 module?
Siemens identifies the module as a 60 A Single Motor Module.
What lifecycle status applies to this order number?
The official product page marks it at the end of its product lifecycle.
Which successor does Siemens identify?
Siemens identifies 6SL3121-1TE26-0AA3 as the successor product.
Is the AA3 successor automatically a drop-in replacement?
No. The complete drive project, hardware interfaces, firmware, safety functions and cabinet cooling must be verified.
What cooling design must be retained?
The module uses external air cooling, so the installed airflow path and cabinet interface are essential.
Which details should accompany an enquiry for this legacy module?
Include the AA0 nameplate, motor data, drive topology, cooling arrangement, quantity and whether an AA3 migration is acceptable.
