Siemens 6SL3352-6TG41-3AA3 Replacement Control Interface Board
A replacement control-interface board for a 3 AC 500–690 V, 50/60 Hz, 1270 A SINAMICS motor-module configuration.
Technical Summary
6SL3352-6TG41-3AA3 is a Siemens SINAMICS S replacement control-interface board for a 3 AC 500–690 V, 50/60 Hz, 1270 A Motor Module. It belongs to the chassis-drive service hardware used between the control and power-stage assemblies.
The complete -3AA3 suffix identifies the 1270 A variant. Siemens service material associates this legacy board with replacement subassemblies 6SL3350-6TK00-0EA0 and 6SL3352-3AG41-3AB0; the applicable service procedure and installed hardware release still require confirmation.

Features
- Provides the control-to-power-stage interface for the documented 1270 A Motor Module configuration.
- Preserves the complete Siemens MLFB required for high-voltage chassis-drive service.
- Supports controlled replacement of the legacy interface board with the documented Siemens service split.
- Keeps voltage class, current class and hardware release tied to one maintenance record.
Compatibility
- Match the installed SINAMICS Motor Module, 500–690 V class and 1270 A rating.
- Compare every firing, feedback and internal control connector with the removed board.
- Confirm host firmware, control-unit release and Siemens service instructions.
- Do not substitute the visually similar 6SL3352-6TG41-0AA3 1025 A variant.
Replacement
- Archive drive parameters, diagnostics, hardware labels and connector photographs before removal.
- Apply the approved lockout, DC-link discharge and ESD procedure for the chassis drive.
- After installation, verify gate-channel feedback, internal communications, diagnostics and controlled load operation.
FAQ
6SL3352-6TG41-3AA3: What evidence prevents the 1270 A board from being confused with the 1025 A version?
Send both the interface-board label and the Motor Module nameplate. The complete -3AA3 suffix and 1270 A host rating must agree before quotation.
6SL3352-6TG41-3AA3: Should the legacy board or the Siemens replacement split be requested?
State whether the requirement is an exact legacy spare or an approved service conversion. The quote should identify every supplied subassembly and the applicable installation instruction.
6SL3352-6TG41-3AA3: Which removed-part photographs are most useful?
Capture the front and rear labels, connector keying, firing leads, feedback plugs, adjacent boards and cabinet position before any cable is moved.
6SL3352-6TG41-3AA3: Can a repaired board be installed without restoring the previous parameter set?
No. Hardware service should be followed by the approved parameter restore, diagnostic review and staged functional test for the host drive.
6SL3352-6TG41-3AA3: What should be agreed for a critical-outage order?
Agree condition, hardware revision, test evidence, included subassemblies, preservation, lead time and return-core requirements in writing.
6SL3352-6TG41-3AA3: Which acceptance test reduces restart risk?
Use controlled energization, verify all gate and feedback channels, review fault history, and complete a limited-load run before returning the machine to production.
