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.
What the ratings mean for fit
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. IP20 / UL Open Type means this drive is intended for installation inside a locked electrical enclosure — not for washdown or outdoor mounting. The FSA frame size dictates a 73 mm wide footprint on the DIN rail, which is the smallest in the G120C family and leaves room for a bypass contactor or output reactor in the same panel row.
