6SE6400-3TD06-1EE0

The Siemens part 6SE6400-3TD06-1EE0 functions as an output filter, specifically an LC filter, designed for 3-phase systems. It operates effectively within a voltage range of 380 to 480 volts AC. With a frame size categorized as E, this output filter is capable of handling currents of 63.2 amps at 40 degrees Celsius, reducing to 45 amps at 50 degrees Celsius. This means it is robust enough for substantial power requirements.

Designed for stand-alone mounting, the filter is encased in either an IP00 or IP20 enclosure, which indicates it is intended for dry installation environments without high levels of dust or moisture. The overvoltage category is Class III, indicating safe operation under various environmental conditions. The insulation class is rated H, allowing it to function at temperatures as high as 180 degrees Celsius.

Users can set the maximum motor frequency at 150 Hz, along with a motor overvoltage limitation set approximately at 1078 volts, which protects against voltage spikes. The unit accommodates a maximum motor feeder cable length of 200 meters when using shielded cables and up to 300 meters with unshielded cables, ensuring flexibility in installation and wiring. It’s worth noting that the pulse frequency of 4 kHz is recommended since using a pulse frequency of 2 kHz can lead to overheating. The permissible ambient temperature ranges from -10 to 40 degrees Celsius when operating at full rated current, which supports its application in varying temperature conditions.
