The Siemens 4EU3622-8FA00-0AA0 is a 3-phase commutating choke (line reactor) designed for converter drives. Rated at 492 A continuous and 400 V AC at 50 Hz, it smooths current ripple and limits di/dt on the input side of a variable-frequency drive or DC drive converter. Inductance is 0.000052 H with a relative inductive voltage drop of 4 % at rated current and frequency.
The lifecycle stage is marked as mature, meaning the part is in stable, ongoing production — not a new introduction and not flagged for phase-out. It remains available through standard Siemens distribution channels and is sourced to order against an RFQ.
The choke measures 0.35 m wide by 0.321 m tall by 0.237 m deep (350 × 321 × 237 mm) and is rated IP00 — open-frame, no enclosure. It is intended for mounting inside a switchgear cabinet or drive cubicle where the ambient temperature does not exceed 40 °C. The thermal class H insulation (IEC 60085) means the winding can withstand sustained temperatures up to 180 °C, providing a generous margin above the 40 °C ambient. Main-circuit connections are via flat-type terminals (busbar or flat-cable lugs). Plan the busbar interface into the panel layout — no screw-clamp or spring-cage terminals here.
