Siemens 6SL3351-6GE32-1AA1 MICROMASTER 440 Control Interface Board
A replacement control-interface board for the documented 3AC 380–480 V MICROMASTER 440 FX drive execution.
Product Profile
6SL3351-6GE32-1AA1 is a Siemens replacement Control Interface Board for MICROMASTER 440 drives. Siemens spare-parts documentation assigns it to frame size FX and the 3AC 380–480 V, 50/60 Hz, 210 A drive execution.
The GE32 identity must not be merged with FE33 or another MICROMASTER interface board. Correct service selection uses the exact board number, complete MICROMASTER 440 host MLFB and saved parameter and option records.
