Stromrichter) sized for converter input circuits. Its job is to limit the rate of rise of fault current and reduce harmonic distortion on the line side of a variable-frequency drive or DC drive supply. Rated for 639 A continuous (710 A maximum) at 400 V AC, 50 Hz, with an inductance of 0.037 mH, it handles the high RMS currents typical of large motor drives — think 250+ kW induction motor loads on a conveyor, pump, or compressor. Thermal class H (180 °C) insulation means the winding can run hot in a crowded cabinet; the 280 W coil loss plus 195 W iron-core loss (475 W total) needs ventilation clearance around the 0.227 m depth × 0.35 m width × 0.321 m height body. ## IP00 and flat-type terminals — what that means for panel fit IP00 means no ingress protection: the choke has no enclosure. It mounts inside a cabinet (typically a drive panel or converter cubicle) where the overall assembly provides the IP rating. The flat-type terminals (flat connector per) accept bus-bar or cable-lug connections — not spring-cage or screw-clamp. Plan for bolted terminations sized to the 639 A continuous current. The 0.35 m width and 0.227 m depth footprint fits a standard 800 mm-wide enclosure bay, but the 0.321 m height may conflict with bus-bar runs above the drive. Check the cabinet's internal clearances before committing the BOM line. The part carries an EN 61558-2-20 compliance reference (safety of transformers, reactors, and power supply units), which covers the choke's construction and testing. No UL or CSA listing appears in the evidence — verify with your local codes if the installation requires third-party certification.","metaTitle":"Siemens 4EU3622-3AA00-1BA0 Commutating Choke, 710A, 400V AC","metaDescription":"Siemens 4EU3622-3AA00-1BA0 commutating choke for converter drives.
