The Siemens 4EU2422-0EA00-4BA0 is a commutating choke (line reactor) for converter applications — 3-phase, 460V AC, rated 90A continuous with a 100A maximum. The 0.29mH inductance limits current rise and harmonic distortion on the input side of a variable-frequency drive or DC drive converter. Thermal class H insulation (180°C rated) means it handles the heat buildup in a closed panel without derating prematurely.
Where it fits — panel and mounting
IP00 means no enclosure — this choke mounts inside a cabinet, not in a washdown area. The flat-type terminals accept busbar or cable lugs, not spring-cage or screw-clamp wire ends. Footprint: 0.225m wide × 0.21m tall × 0.136m deep. That depth is the body depth, not including terminal protrusion — allow 20-30mm extra for lug overhang when laying out the gland plate. No DIN-rail clip; it bolts directly to the panel backplate.
The 100A maximum is the short-time overload — do not size a 90A motor and expect the choke to carry 100A indefinitely. The DC rated value of 122.5A applies if the choke is used on the DC link side of a converter, not the AC input. The 0% relative inductive drop means the voltage drop across the choke at rated current is negligible for most line-regulator calculations — the 4% impedance figure in the description is the more practical number for sizing voltage drop and harmonic attenuation.
