The Siemens 4EU3622-1CA00-0AA0 is a three-phase commutating choke (line reactor) for converter applications, designed to limit current rise and reduce harmonic distortion on the AC input side of a variable-speed drive or rectifier.
The 630 A AC maximum current rating defines the thermal limit under continuous AC load. The 567 A AC operational current is the design point where the 4% voltage drop is guaranteed. Peak current capability is 788 A. The flat-type main circuit terminals accept busbar or cable lugs; plan for bolted connections sized to the 630 A continuous rating.
Physical integration — dimensions and mounting
The choke measures 0.35 m wide, 0.321 m high, and 0.227 m deep. These are the overall envelope dimensions. Mounting is inside a cabinet (IP00); allow clearance for cooling given the combined coil and iron-core power loss of 293 W and 140 W.
