Compatible Replacement & Equivalent Models
When the original 6SL3352-6TG37-4AA3 is unavailable or discontinued, the following models may serve as functional equivalents or replacements (subject to engineering verification):
- 6SL3352-6TG38-8AA3 – Higher power rating variant in the same S120 Active Line Module family
- 6SL3352-6TG35-0AA3 – Lower power variant, suitable for de-rated applications
- 6SL3130-7TE37-5AA3 – S120 Active Line Module (booksize), comparable DC bus output
- 6SL3130-6AE21-0AB0 – Smart Line Module alternative for non-regenerative applications
- ABB ACS880 Power Module – Cross-brand alternative; requires interface adapter and engineering review
- Rockwell Allen-Bradley 2198-Dxxx – Cross-brand alternative for Kinetix platform; not a drop-in replacement
⚠ Important: Cross-brand replacements require full engineering validation. Contact [email protected] for compatibility assessment.

Selection Guide
Use the following criteria to confirm the 6SL3352-6TG37-4AA3 is the right choice for your application:
- ✅ Power Requirement: Your application requires ~750 kW active line supply
- ✅ Regeneration: You need energy recovery / regenerative braking capability
- ✅ Cooling: Your cabinet supports liquid cooling infrastructure
- ✅ Voltage: Supply is 3-phase 380–480 V AC
- ✅ Platform: Your system is based on SINAMICS S120 architecture
- ❌ If non-regenerative: Consider Smart Line Module 6SL3130-6AE2x-xABx for lower cost
- ❌ If lower power: Select a lower-rated Active Line Module from the 6SL3130 / 6SL3352 range

Replacement & Compatibility FAQ
Q: Is 6SL3352-6TG37-4AA3 discontinued?
A: Siemens periodically updates its product lifecycle. Contact us to confirm current availability and recommended successor models.
Q: Can I replace 6SL3352-6TG37-4AA3 with a Smart Line Module?
A: Only if your application does not require regenerative energy feedback. Smart Line Modules are non-regenerative and have different harmonic characteristics.
Q: What is the difference between 6SL3352 and 6SL3130 series?
A: The 6SL3352 series typically refers to liquid-cooled cabinet-format modules, while 6SL3130 covers booksize air-cooled variants. Power ratings and mounting differ significantly.
Q: Do you provide a warranty on surplus units?
A: Yes. We offer a 12-month warranty on all tested refurbished units and full OEM warranty on new factory-sealed stock.
Q: Can Konmask assist with installation or commissioning?
A: We provide technical documentation and remote guidance. On-site commissioning support can be arranged through our partner network.
