Siemens 6SL3120-1TE24-5AA3 SINAMICS S120 45 A Single Motor Module
Legacy 45 A module with 85 A maximum current and 6SL3120-1TE24-5AC0 successor guidance.
01Overview
Siemens 6SL3120-1TE24-5AA3 is a legacy 45 A internal-air-cooled SINAMICS S120 Single Motor Module. Its data sheet specifies 38 A base-load current, 60 A S6 current and 85 A maximum current in a 150 mm-wide booksize enclosure. Siemens identifies this article as a spare part that is no longer available and points to 6SL3120-1TE24-5AC0 as the successor. The successor is physically narrower and has different cooling, capacitance and maximum-current values, so it must be treated as an engineered conversion rather than a simple suffix change.

03Features
Product Functions
- Delivers 45 A rated output for one S120 motor axis.
- Provides 60 A intermittent current and 85 A maximum current for the AA3 generation.
- Uses an M6 bolted motor connection accepting conductors from 2.5 to 50 mm².
- Supports extended Safety Integrated functions and optimized pulse patterns.
- Allows motor-cable runs up to 100 m shielded.
- Uses a 150 mm booksize construction with a 0.031 m³/s cooling-air requirement.
Identification
- Manufacturer: Siemens
- Model: 6SL3120-1TE24-5AA3
- Product Type: Legacy SINAMICS S120 booksize Single Motor Module
- Status: Spare part / no longer available
04Applications
- Exact spare replacement for installed 45 A AA3 power sections.
- Legacy axes whose drive project and cable termination are built around the 150 mm module.
- S120 multi-axis systems requiring the documented 45 A / 85 A current profile.
- Planned migration projects comparing the AA3 mechanical envelope with the C-type successor.
- Industrial cabinets where the original M6 connection and cooling arrangement are documented.
05Lifecycle
- Siemens identifies the article as a spare part that is no longer available.
- The official successor is 6SL3120-1TE24-5AC0.
- The successor is 100 mm wide rather than 150 mm and uses different airflow, capacitance and loss values.
- Preserve the drive project, hardware recognition data, motor cable and safety configuration before migration.
- Validate mounting, busbar alignment, conductor routing, overload response and thermal operation after conversion.
06FAQ
What maximum current is specified for the 45 A AA3 module?
The exact Siemens data sheet lists 85.0 A maximum current.
How wide is 6SL3120-1TE24-5AA3?
The legacy booksize module is 150 mm wide.
Which successor does Siemens identify?
Siemens points to 6SL3120-1TE24-5AC0 as the successor product.
Why is the AC0 successor not a mechanical drop-in assumption?
The AC0 is 100 mm wide and has different airflow, DC-link capacitance, power-loss and maximum-current values.
