Reduces motor noise and EMI Compatible with MICROMASTER 4 Smooths output voltage Rated for 380-480V FS D size for specific drives Improves EMC compliance

Product description

The Siemens 6SE6400-3TD03-7DD0 is an output LC filter designed for the MICROMASTER 4 series of variable frequency drives. It is rated for a 380-480 V 3-phase AC input and can handle a current of 38.8 A at 40 °C or 32.0 A at 50 °C. The filter is in size FS D with dimensions of 278x240x230 mm (HxWxD). It helps to reduce motor noise and electromagnetic interference (EMI) by smoothing the output voltage waveform.

This LC filter is essential for applications where motor noise reduction and EMI suppression are critical. It is used in conjunction with MICROMASTER 4 drives in various industrial settings, including HVAC systems, pump and fan controls, conveyor systems, and general machine building, to ensure compliance with EMC regulations and improve system reliability.
