Provides the documented control-interface board execution for the 210 A MICROMASTER 430 FX drive.
Product Identification
6SL3351-6FE32-1AA1 is a Siemens replacement control interface board for the MICROMASTER 430 platform. Siemens lists it for a 3AC 380–480 V, 50/60 Hz, 210 A drive execution in frame size FX.
Its FE32-1 code and 210 A host rating separate it from the 260 A FE32-6 board even though both belong to the MICROMASTER 430 FX family.

Allows controlled board service when configuration and connector records are preserved.
Applications
- MICROMASTER 430 FX drives whose rating plate confirms 210 A at the specified supply class.
- Exact board-level replacement where 6SL3351-6FE32-1AA1 is present on the assembly.
- Asset-specific spare management for legacy fan and pump drive installations.
- Controlled recovery after diagnostic work confirms the board as the required service item.
Lifecycle
- Preserve parameters, motor data, option settings and fault history.
- Record the host MLFB, serial number, board label and connector positions.
- Confirm an approved Siemens supersession before accepting a different suffix or current class.
- Use ESD, lockout and DC-link discharge controls during replacement.
- Recommission with diagnostics, motor current, direction and interlocks monitored.

FAQ
Can the 260 A FE32-6 board replace 6SL3351-6FE32-1AA1?
Do not assume so. Siemens lists FE32-1 for the 210 A execution and FE32-6 for 260 A, so the host rating and approved spare path must match.
What label confirms the application for 6SL3351-6FE32-1AA1?
The host-drive rating plate must show MICROMASTER 430, the applicable supply class, 210 A and FX frame context.
What records reduce commissioning time for 6SL3351-6FE32-1AA1?
A validated parameter archive, option list, connector photographs, motor nameplate and recent fault history are most useful.
What safety delay applies before handling 6SL3351-6FE32-1AA1?
Use the discharge time and voltage-verification method specified for the exact MICROMASTER 430 host; never rely only on indicator lamps.
What should be monitored on first run with 6SL3351-6FE32-1AA1?
Check DC-link and drive diagnostics, motor current and direction, command sources, feedback, interlocks and the driven process response.
