Siemens 6SL3210-1KE22-6UB1 is a SINAMICS G120C compact converter for three-phase 380–480 V AC supplies. The exact configuration delivers 11.0 kW under low-overload duty, uses an unfiltered power stage, and provides USS/Modbus RTU fieldbus communication.
The integrated I/O interface includes digital, analog and motor-temperature connections, while Safe Torque Off supports safety-oriented machine designs. Frame size FSC and the published mechanical dimensions must be checked against cabinet space, cooling and EMC requirements before replacement or new installation.
