The 6SE6400-3TD18-0FD0 from Siemens is categorized as an output filter (LC filter) tailored for three-phase systems. The voltage rating ranges from 380 to 480 volts AC. This product operates at a maximum current of 181.6 amps when the ambient temperature is at 40 degrees Celsius, and the rating decreases to 145 amps at 50 degrees Celsius.

Designed in Frame Size F, the device comes in an IP00 / IP20 enclosure type. It is configured for stand-alone mounting, allowing for easy integration into existing systems. The unit meets Overvoltage Category III (VDE 0110) standards and is rated under Insulation Class H, affirming its capability for thermal resistance.

Motor frequency is governed up to a maximum of 150 Hz, providing flexibility in various applications. It also includes a motor overvoltage limitation at approximately 1078 volts. The specifications allow for a maximum shielded motor feeder cable length of 200 meters and up to 300 meters without shielding. }

To ensure reliable operation, it is crucial to maintain a pulse frequency of 4 kHz, as using a 2 kHz pulse frequency can lead to overheating. This output filter is integral for applications requiring precise control and protection in regular operation.
