Siemens 6SL3310-1GH31-2AA3 SINAMICS G130 Power Module IP20 690V 120A 110kW VFD Power Module

The Siemens 6SL3310-1GH31-2AA3 is a SINAMICS G130 power module rated 660-690 V 3AC, 50/60 Hz, at 120 A, giving a 110 kW type rating. It uses a 6-pulse supply design without power recovery, ships in IP20 protection, and includes a CIM board with Drive-CLiQ cable; the control unit is ordered separately. Net weight is 104.0 kg.

Selection Notes

At 120 A / 110 kW, this sits between the 100 A and 150 A ratings in the same 104.0 kg IP20 frame; choose it when the connected motor's rated current is close to 120 A rather than derating a smaller module or oversizing the next one up. IP20 protection is sufficient when the module sits inside a control cabinet that already keeps out dust and contact, so it mounts directly on the cabinet backplate without a further enclosure. Because the supply section is a 6-pulse design without power recovery, braking energy from the driven load cannot be fed back to the 660-690 V line; it has to be dissipated through a braking resistor or absorbed by a regenerative unit elsewhere in the line-up, not by this module. It ships as the power stage only, with the CIM board and Drive-CLiQ cable fitted but no control module, so a SINAMICS control unit has to be ordered and connected separately before the drive can run a motor. The Drive-CLiQ cable is Siemens' point-to-point digital link between the power module and the control unit, carrying parameter and diagnostic data over a single cable instead of discrete analog wiring.

Applications

This power module is the rectifier/inverter stage of a SINAMICS G130 single-axis chassis drive; it needs a control unit to operate and is built for mounting inside a control cabinet rather than as a stand-alone unit, consistent with its IP20 degree of protection.
