Product Overview

The 6SE6400-3TD03-7DD0 is an LC line filter in Siemens' MICROMASTER 4 accessory family, intended for insertion between the mains supply and a MICROMASTER inverter to reduce electromagnetic interference and smooth motor drive input power. The filter is designed for frame size D and operates over a nominal supply voltage of 380-480 V AC. In industrial control systems, such filters are typically paired with variable frequency drives in manufacturing, HVAC, or motor control installations to comply with EMC requirements and protect downstream equipment. Part number 6SE6400-3TD03-7DD0 enables reliable filtering of drive input circuits.
