The Siemens 6SL3210-1KE14-3UB1 is a SINAMICS G120C compact frequency inverter rated 1.5 kW at 4.1 A for low-overload duty (pumps, fans, conveyors) and 1.1 kW at 3.1 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 FSA.
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.

Typical applications
- Centrifugal pumps, booster sets and water treatment
- Fans, blowers and air handling units
- Conveyors, roller tables and packaging machines
- Mixers, agitators and extruder auxiliaries
- Replacement of a failed G120C of the same rating
Compatibility and replacement
In the Siemens order number, U = unfiltered and B = USS/Modbus RTU. 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.
Frequently asked questions
Is a control panel included?
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.
Which power should I choose, LO or HO?
Use the low-overload rating (1.5 kW) for pumps and fans, and the high-overload rating (1.1 kW) for conveyors, hoists or machines with heavy starting torque.
