SINAMICS G120C, 3.0 kW — panel integration brief
This 6SL3210-1KE17-5UC0 is a SINAMICS G120C variable-frequency drive rated for 3.0 kW output with 150% overload for 3 seconds, on a 380-480 VAC 3-phase supply at 47-63 Hz. The unfiltered variant keeps the enclosure depth to 73 mm on the FSA frame (196 x 73 x 203 mm HxWxD), which fits tight DIN-rail rows in a standard IP20 panel — no extra clearance for a line filter bracket. The integrated Safe Torque Off eliminates the need for a separate safety relay on the motor branch, saving two DIN-rail units. The I/O complement — 6 digital inputs, 2 digital outputs, 1 analog input, 1 analog output — covers basic conveyor or pump control without an expansion module. CANopen is onboard, so no option card is needed for that fieldbus slice.
The 150% overload for 3 seconds is the key selection figure: it handles the starting current of a 3.0 kW induction motor driving a loaded conveyor or a centrifugal pump without nuisance tripping. The 380-480 VAC input range covers standard European and North American three-phase supplies without a transformer.
