The Siemens 6SL3330-6TE41-1AA3 SINAMICS S120 Smart Line Module is a high-power line-infeed component within the SINAMICS S120 drive platform. Siemens identifies the exact article number for a 380–480 V three-phase AC supply at 50/60 Hz, with a 510–650 V DC output range, 1050 A rated DC output current and 500 kW rated power. The manufacturer lists the unit as an IP00 built-in module with internal air cooling and a DRIVE-CLiQ cable. The live Auto2mation listing independently records 883 A on the line-input identification and a complete assembly weight of 292 kg.

The Auto2mation page also identifies 6SL3352-1AE38-4CA1 as an associated power block. Its label data is different from the complete Smart Line Module: the page records DC 510–750 V input and 840 A output for that power block, while the complete 6SL3330-6TE41-1AA3 is listed with 1050 A rated DC output. Keeping the main module and subassembly values separate is important when procurement or maintenance teams compare an installed unit. The article therefore treats the Siemens article number as the primary identification and uses the power-block number only as a verified assembly reference.

Applications & Use Cases

The module is relevant to industrial automation systems engineered around the SINAMICS S120 platform. Siemens positions Smart Line Modules on the line-infeed side of the S120 system, where they interface with the DC-link architecture supplying connected drive components. Selection is therefore based on the coordinated drive-system design rather than on a single current or power value.

For replacement planning, the incoming three-phase supply, DC-link range, cabinet arrangement, cooling path and connected S120 components should be checked against the original machine documentation. The 500 kW and 1050 A ratings identify the electrical scale of the complete line module, while the separate power-block number can help identify the internal assembly without changing the main module rating.

Why Choose the Siemens 6SL3330-6TE41-1AA3

A key reason to select this exact article number is electrical matching within an existing SINAMICS S120 system. The verified 380–480 V input range, 510–650 V DC output and 1050 A rated current define the operating envelope that must align with the original drive architecture.

The IP00 built-in format also matters at installation level. The surrounding cabinet provides the protective enclosure, while Siemens specifies internal air cooling. Airflow and cabinet design are therefore part of the equipment integration rather than separate generic assumptions.

The associated 6SL3352-1AE38-4CA1 power-block identification gives maintenance teams another useful matching point. Because its 840 A marking belongs to the power block, keeping it distinct from the complete module’s 1050 A rating helps prevent specification errors during comparison.

Compatibility & Integration

Before replacement, verify the full Siemens article number, input supply, DC-link requirement, rated current, cooling arrangement and the existing SINAMICS S120 configuration. For manufacturer-level reference, consult the Siemens Industry Mall product entry for 6SL3330-6TE41-1AA3.

Do not treat a similar 6SL3330 or 6SL3352 suffix as automatically interchangeable. Compare the complete order code and physical assembly identifiers against the existing machine before integration.

Maintenance & Support

For an internally air-cooled IP00 module, maintenance should follow the original machine and Siemens service documentation. Cabinet ventilation, airflow paths and electrical connections are important inspection points because the surrounding enclosure is part of the installation design.

Any servicing activity should be carried out using the equipment’s electrical isolation procedure. After work is completed, confirm module identification, DC-link connections and cooling installation before the drive system is returned to operation.

Frequently Asked Questions

Q1: What is the Siemens 6SL3330-6TE41-1AA3?

It is a SINAMICS S120 Smart Line Module identified by Siemens for 380–480 V three-phase AC input, 510–650 V DC output, 1050 A rated DC output current and 500 kW rated power.

Q2: What is the rated DC output current?

Siemens lists 1050 A for the complete Smart Line Module, and the Auto2mation listing records the same main-module output current.

Q3: What is 6SL3352-1AE38-4CA1?

Auto2mation identifies it as an associated power block with DC 510–750 V input and 840 A output markings.

Q4: Is the 840 A power-block value the same as the Smart Line Module rating?

No. The 840 A value is recorded for the associated power block, while the complete 6SL3330-6TE41-1AA3 is rated at 1050 A DC output.

Q5: What should be checked before replacement?

Check the complete article number, AC input, DC-link range, current rating, cooling arrangement and existing SINAMICS S120 system design.
