Siemens 6SL3131-7TE31-2AA3 SINAMICS S120 Active Line Module
A 120 kW booksize Active Line Module with 380–480 V three-phase input, 600 V DC output and a 200 A DC-link rating.
Overview
6SL3131-7TE31-2AA3 is a high-power SINAMICS S120 Active Line Module in booksize format with external air cooling. It provides a 120 kW regenerative infeed for a compatible S120 DC-link system and includes the specified DRIVE-CLiQ cable.
The unit is identified by Siemens as a spare part following product cancellation. Its 200 A rating, 300 mm booksize construction and external cooling arrangement distinguish it from the lower-power 6SL3131-7TE28-0AA3 and from internally cooled 6SL3130 variants.

Features
- The 120 kW infeed supports both motoring energy flow and regenerative feedback in an engineered S120 line-up.
- A regulated 600 V DC link supports coordinated operation of connected booksize Motor Modules.
- External air cooling routes the principal power-section heat through the rear cooling channel.
- The 200 A rated DC-link connection is sized for the published 120 kW class and its supported duty profile.
- DRIVE-CLiQ provides the control and diagnostic connection to the compatible S120 system architecture.
Applications
- Spare-part support for installed SINAMICS S120 line-ups using this exact 120 kW external-air-cooled Active Line Module.
- High-power coordinated drive systems that require regenerative energy exchange with the three-phase supply.
- Production and motion-control machinery with a 600 V DC-link architecture and compatible S120 Motor Modules.
- Cabinet constructions engineered for the 300 mm booksize footprint, rear airflow path and specified line-side components.
Lifecycle
- Siemens identifies this article as a spare part and records product cancellation effective 1 October 2021.
- Replacement planning should retain the complete article number and compare the 120 kW rating, external cooling, DC-link current and version suffix.
- Record the Active Interface Module, line filter, protective devices, DRIVE-CLiQ topology, DC-link arrangement and cabinet opening before exchange.
- For modernization, verify the mechanical, electrical, firmware and commissioning implications across the complete S120 drive line-up rather than matching power alone.
FAQ
Is 6SL3131-7TE31-2AA3 still an active standard product?
Siemens records product cancellation from 1 October 2021 and identifies the article as a spare part.
What rated infeed does the module provide?
The rated infeed and regenerative power is 120 kW with a 200 A DC-link rating.
How is the power section cooled?
It uses external air cooling with an integrated fan and requires the matching cabinet airflow arrangement.
Can the 80 kW 6SL3131-7TE28-0AA3 replace it?
No. The 80 kW model has different power, current, capacitance and thermal data.
What line-side equipment must be retained or rechecked?
Verify the Active Interface Module, filtering, fuses or circuit breaker, conductors and grounding for the exact 120 kW design.
Which records are most important before service replacement?
Keep the article number, project backup, DRIVE-CLiQ topology, infeed parameters, DC-link arrangement and cabinet cooling details.
