The Siemens 4EU2722-4CA00-0AA0 is a 3-phase commutating choke for converter applications, rated 500 V AC with a maximum continuous AC current of 250 A at 50 Hz. It delivers 225 A rated operational current with a relative inductive voltage drop of 4% at rated conditions. The choke is built to thermal class H per IEC 60085, meaning it can sustain 180 °C hot-spot temperature — essential for high-duty-cycle converter drives where harmonics and switching transients generate sustained heat.
IP00 enclosure means the choke is open-frame — intended for installation inside a switchgear cabinet or converter cubicle where the enclosure provides the environmental seal. The flat-type terminals accept busbar or lug connections typical of high-current power paths. Panel builders should plan for the 0.187 m depth, 0.27 m width, and 0.248 m height when laying out the cubicle floor or mounting plate.
Lifecycle stage is classified as mature. The part is not in active phase-out; it remains in the Siemens portfolio for ongoing converter builds and retrofit spares.
Total power loss at rated conditions sums to 254 W (174 W coil loss plus 80 W iron-core loss). The DC-rated current of 306.3 A and peak current of 313 A give headroom for transient overloads — the choke can handle short-duration current spikes without saturating the core, which is critical for converter commutation circuits where the current waveform is non-sinusoidal.
