Siemens 6SL3985-6TM00-0AA0 TAS21E Thyristor Electronics
Crowbar-control electronics for a designated SINAMICS GM150 IGBT drive execution.
Product Overview
6SL3985-6TM00-0AA0 identifies Siemens TAS21E thyristor electronics used to control the crowbar in a designated SINAMICS GM150 IGBT system. It is a protection-circuit component within the medium-voltage drive, not a stand-alone converter.
Selection must be tied to the exact GM150 voltage execution, crowbar hardware, wiring and cabinet documentation. Similar TAS21E references exist for other voltage classes.
Performance
- Protection behavior depends on the complete crowbar circuit and drive configuration.
- Correct voltage-class selection is essential because related TAS21E articles serve other GM150 executions.
- Functional acceptance requires the approved medium-voltage service and test procedure.

FAQ
What does 6SL3985-6TM00-0AA0 control?
It is TAS21E electronics for the crowbar-control function in the 2.3 kV SINAMICS GM150 IGBT execution.
Is 6SL3985-6TM00-0AA0 a complete crowbar assembly?
No. It is an internal electronics component used with the matching crowbar and drive protection hardware.
Can another TAS21E reference replace 6SL3985-6TM00-0AA0?
Do not assume so; related articles can target different GM150 voltage classes and cabinet arrangements.
What information is needed to quote 6SL3985-6TM00-0AA0?
Send the drive nameplate, voltage class, module label, crowbar assembly details, cabinet drawings and failure report.
Who should install 6SL3985-6TM00-0AA0?
Qualified medium-voltage drive personnel following the applicable GM150 safety and commissioning procedure.
What should be tested after replacing 6SL3985-6TM00-0AA0?
Validate wiring and insulation first, then complete the specified protection-circuit diagnostics and controlled drive tests.
