When a 37 kW pump or fan sits on a 200-240 V supply and the network is PROFINET, this SINAMICS G120X drops into the cabinet with no step-up transformer — it runs straight on the low-voltage three-phase supply common in North American and regional sites.

At 37 kW it delivers 176 A at 110% overload for 60 s in a 305 x 709 x 360 mm FSF frame, IP20 for control-cabinet installation. PROFINET and EtherNet/IP are onboard, so the unit joins an industrial-Ethernet controller as a native node with no protocol gateway. This variant ships without DC terminals, which keeps it lean when the motor cable is short and no external du/dt filter is planned.

For serial or BMS buses the 41487 sibling speaks USS, Modbus RTU and BACnet; for PROFIBUS the 41488 sibling is the match on the same 37 kW platform. The 41490 sibling adds DC terminals for an external brake resistor or du/dt filter.
