Rated at 900 A continuous with a 1000 A maximum, it operates at 400 V AC, 50/60 Hz, with an inductance of 0.022 mH and a relative inductive voltage drop of 3.04% at rated conditions. The 1000 A maximum / 900 A rated current tells you this choke is sized for a high-power drive line — think large pumps, compressors, or conveyor systems drawing 900 A continuous. The 3.04% voltage drop at rated current is typical for a line-side choke; it smooths the DC bus ripple and limits peak currents during commutation. Thermal class H (IEC 60085) means the insulation system withstands 180 °C hot-spot temperature — essential in a high-current, enclosed panel where ambient can hit 40 °C. IP00 protection means it is an open-frame component: it must be installed inside a cabinet with proper clearance and ventilation; not for standalone outdoor or washdown use. This choke mounts into a panel or drive cabinet via its flat-type terminals (main circuit connection) — no DIN-rail clip, no screw-on base. The 0.229 m depth, 0.41 m width, and 0.385 m height mean it needs a dedicated footprint in the enclosure; allow for air circulation around the core, especially given the 40 °C ambient rating and class H thermal margin. The flat connectors are sized for bolted bus-bar or cable-lug terminations typical of high-current power sections.","metaTitle":"Siemens 4EU3922-0AD00-0A Commutating Choke, 1000 A, 400 V, 3","metaDescription":"Siemens 4EU3922-0AD00-0A commutating choke for converter, 3-phase, 400 V AC, 1000 A max, 900 A rated, 0.022 mH, IP00, thermal class H.
