Description
About the 6SL3210-1PH22-3UL0
About the 6SL3210-1PH22-3UL0
The Siemens 6SL3210-1PH22-3UL0 is a SINAMICS G120 PM240-2 power module for 3AC 500-690V supply, rated 15.00 kW at high overload and 18.50 kW at low overload in the FSD frame. The module integrates a braking chopper, has no input filter, and ships without a control unit or operator panel; it runs from CU firmware V4.7 HF8. It weighs 17.4 kg with IP20 protection in the 472 x 200 x 237 mm FSD frame.
Selection Notes
This is the top of the mid-range FSD lineup in this batch before stepping up to the FSE frame at 37.00 kW low-overload; pick it over the 11.00 kW / 15.00 kW module when the driven load's continuous current draw is closer to 23.00 A than to 19.00 A. Max. output current of 38.00 A gives headroom for the 200% / 3 s overload window on high-overload duty, which matters for machines with high breakaway torque, such as positive-displacement pumps. Since the module ships unfiltered, plan for an external EMC filter if conducted-emission limits apply to the installation.
