Why This Model?
The 11kW model represents the maximum power offering in the MICROMASTER 420 series, making it the go-to choice for applications that require the highest power density within this product family. It shares the same C-size chassis as the 5.5kW and 7.5kW models (245mm height), providing excellent power-to-space ratio.

For applications that have outgrown lower-power drives, the 11kW model offers a straightforward upgrade path without changing product families or significantly altering control cabinet layouts.

Important Note: This product has been discontinued by Siemens (PM410 - Product Cancellation effective 01.10.2019). Available only while limited stocks last. Contact us for current availability.

Selection Guide:
Select 11kW when your motor is rated 11kW (15 HP) at 380-480V. This is the maximum power in the MICROMASTER 420 series. For higher power requirements, consider the MICROMASTER 430 series (up to 250kW) or the SINAMICS G120 series.

FAQ:

Q1: Is this the largest VFD in the MICROMASTER 420 series?
A: Yes. The 6SE6420-2UD31-1CA1 is the highest power model in the MICROMASTER 420 series at 11kW (380-480V input). For higher power requirements, the MICROMASTER 430 or SINAMICS G120 series are recommended.

Q2: Is this product still in production?
A: No. This product has been discontinued by Siemens with PM410 status (Product Cancellation) effective October 1, 2019. We offer remaining inventory while supplies last. For new designs, Siemens recommends the SINAMICS G120 series as the successor.

Q3: What is the successor product?
A: Siemens recommends the SINAMICS G120 series as the successor to MICROMASTER 420. Contact us for assistance in selecting the appropriate G120 replacement for your application.

Q4: What is the typical lead time for this discontinued model?
A: As a discontinued product, availability is limited to remaining stock. Please contact us for current inventory status and lead times.

Q5: Does Siemens still provide technical support for this product?
A: Limited support is available. Siemens typically provides support for discontinued products for a period after cancellation. For critical applications, we recommend migrating to the G120 series to ensure long-term supportability.
