It carries a maximum current of 140 A at 50 Hz, with a rated continuous current of 126 A, and a rated operating voltage of 500 V AC. The rated inductance is 0.26 mH, with a relative inductive voltage drop of 4% at the measurement level. This is the component that sits between the supply and the converter's input bridge, smoothing the current waveform and protecting the semiconductor switches from excessive di/dt. The 4% voltage drop figure tells you the impedance at rated current — it's a standard value for commutating chokes in this power class, meaning it won't steal significant voltage from the drive's DC bus under load. ## Thermal and environmental ratings Rated for 40 °C ambient, thermal class H insulation. Total power loss 131 W in the coil and 68 W in the iron core. The IP00 protection class means the choke has no enclosure — it's a bare magnetic assembly intended for installation inside a switchgear cabinet or converter cubicle. No washdown tolerance, no dust sealing. Mounting and terminal access must be inside a locked or tool-accessible enclosure per local code. ## Physical fit and connection Dimensions are 0.225 m wide, 0.21 m high, and 0.16 m deep — roughly the footprint of a large contactor. Main circuit connections are flat-type terminals, which accept busbar or cable lug terminations. No DIN-rail mount; it bolts directly to a panel backplate using its own mounting feet.","metaTitle":"4EU2522-6AA00-0AA0 Commutating Choke, 140A, 500V, 3-Phase","metaDescription":"Siemens 4EU2522-6AA00-0AA0 commutating choke for converters. 3-phase, 140A max, 500V AC, 50 Hz, 0.26 mH.
