The Siemens 4EU2752-5UA00-0AA0 is a 3-phase mains choke for variable-frequency drives. It smooths line current and limits harmonic distortion. The 162 A rated current (180 A maximum) and 690 V AC rated voltage suit a medium-to-large drive.
The 162 A rated current is the continuous RMS current the choke can carry at its 40°C ambient rating without exceeding the Class H (180°C) insulation system. The 180 A maximum is the short-term overload ceiling.
The choke measures 0.27 m wide by 0.248 m high by 0.208 m deep. It uses flat-type terminals for the main circuit connection. The IP00 rating means no built-in enclosure protection.
