Siemens 6SE6400-3CC00-4AD3 is a MICROMASTER 4 line commutation choke (line reactor) for 200–480 VAC three-phase power. It contains three inductors at 3.9 mH each (3x3.9 mH) with a rated current of 3.5 A, designed as an input reactor to smooth current for MICROMASTER 4 drives and improve waveform quality. The unit uses the FSA footprint and is not compatible with the V20 footprint; installation should follow the MICROMASTER 4 input reactor guidelines for mounting and wiring.
