The Siemens 6SL3000-2AE41-4AA0 is a SINAMICS motor reactor sized for a Motor Module rated at 710/800 kW on a 380-480V 3AC supply. It sits between the drive output and the motor terminals, smoothing the voltage waveform and limiting the rate of voltage rise (dV/dt) that can stress motor winding insulation on longer cable runs.
What the rating means for fit
The 710/800 kW power band and 380-480V 3AC voltage range tell you this reactor belongs on a high-power SINAMICS Motor Module — think large conveyors, crushers, extruders, or pump drives in the 700–800 kW class. The reactor's impedance is matched to the drive's switching frequency to keep reflected-wave peaks below the motor's insulation withstand. On a 480V system with cable runs over 50 metres, a reactor like this is standard practice to protect the motor from voltage spikes.
