VFD for Compressors: Selection Guide
How to select and size a VFD for screw, reciprocating and centrifugal compressors, covering overload rating, turndown limits and energy savings.
The Siemens 6SL3310-1GH28-5AA3 is a SINAMICS G130 power module in CIM design, FSF frame, rated 85 A at 660-690V 3AC, 50/60 Hz, for a 75 kW type rating. It uses a 6-pulse supply without power recovery and includes a Drive-CLiQ cable; the control module is ordered separately. IP20 protection degree, 104.0 kg net weight, manufactured in Germany.
This is the 660-690V line-voltage variant of the G130 CIM range, built for higher-voltage supplies rather than the 380-480V modules in the 6SL3310-1GE3 line; do not mix it with those on a shared 400V bus. At 85 A / 75 kW it is the entry point of the 690V G130 range shown here, in the same FSF frame used by higher-current 380-480V modules. As with the 380-480V units, the 6-pulse, non-regenerative supply means braking energy must be dissipated through a braking module or resistor, and the control module is a separate order item sized to the same current class.
