The Siemens 6SL3210-1KE21-7UB1 is a SINAMICS G120C compact frequency inverter rated 7.5 kW at 16.5 A for low-overload duty (pumps, fans, conveyors) and 5.5 kW at 12.5 A for high-overload duty, on a 3-phase 380-480 V supply. It is the unfiltered version with USS and Modbus RTU communication on the built-in RS485 port, in frame size FSB.<\/p>\n
The G120C combines power unit and control unit in one compact housing, so it fits small panels and installs quickly. It supports V\/f (linear, square-law and FCC) and sensorless vector control, has a fail-safe digital input for the Safe Torque Off function, a PTC\/KTY motor temperature input and terminals for an external braking resistor. It is commissioned with an optional BOP-2 or IOP-2 operator panel, or from a PC with SINAMICS Startdrive in TIA Portal.<\/p>\n

The same power rating is also available with integrated class A filter (letter A instead of U) and with PROFINET (F), PROFIBUS (P) or CANopen (C) interfaces. If the plate on your old drive shows a different letter, send it to us and we will quote the exact match.<\/p>\n Frequently asked questions<\/h3>\n |
No. The G120C is supplied without an operator panel. Add a BOP-2 or IOP-2 if you want to set parameters at the machine, or commission it from a PC with SINAMICS Startdrive.<\/p>\n
Use the low-overload rating (7.5 kW) for pumps and fans, and the high-overload rating (5.5 kW) for conveyors, hoists or machines with heavy starting torque.<\/p>\n
Yes. RendatSP ships worldwide from Yiwu, China, by air in 5 to 7 days once the part is ready, and every part carries a 1-year warranty. Send the order number and quantity on WhatsApp and we will reply with a quotation.<\/p>\n
