Siemens 6SL3352-1AE37-5BA1 Replacement Power Block
A 745 A SINAMICS replacement power block for the V- and W-phase section of a 380–480 V drive or power module.
Product Overview
6SL3352-1AE37-5BA1 is the Siemens SINAMICS replacement power block assigned to the V- and W-phase section of the corresponding high-current drive or power module. It uses painted modules and nickel-plated busbars for the 380–480 V, 745 A class.
This article complements, but does not duplicate, the rectifier/U-phase 6SL3351 spare. Correct phase assignment and host-module identity are essential before repair.
Performance
- Restores the V- and W-phase power section in the documented SINAMICS host assembly.
- Retains the coated-module and nickel-plated-busbar construction specified by the complete article.
- Supports component-level repair while preserving the original division of power sections.

FAQ
Can 6SL3352-1AE37-5BA1 be installed in the rectifier/U-phase position?
No. Siemens assigns this article to V and W phases; the 6SL3351 article covers the rectifier and U phase.
Is 6SL3352-1AE37-5BA1 a plug-in complete drive replacement?
No. It is a power-block repair spare that requires qualified installation inside the correct host assembly.
What should be checked against the 6SL3352-1AE37-5BA1 nameplate?
Match the complete host article, voltage/current class, hardware revision, coated construction and nickel-plated busbar execution.
Why are cooling checks important after 6SL3352-1AE37-5BA1 installation?
A high-current phase block depends on correct heat transfer, coolant or airflow condition, sensor wiring and thermal protection.
What functional tests should follow 6SL3352-1AE37-5BA1 replacement?
Check insulation, gate control, V/W output symmetry, current feedback, cooling, diagnostics and staged motor operation.
What information should accompany a 6SL3352-1AE37-5BA1 request?
Provide the host nameplate, serial and revision, failure diagnostics, cabinet execution, photographs and the existing phase-block labels.
