Rated for continuous operation at 252 A (I_LN) with a thermal maximum of 280 A at 50/60 Hz, it handles the full rated current of a large drive without saturating. The 0.2 mH inductance (0.0002 H) with a 4% relative inductive voltage drop at rated current means it's sized for moderate impedance — enough to smooth commutation without dropping excessive voltage across the reactor under load. That 4% figure is the voltage drop at rated current and frequency, so the drive sees roughly 96% of line voltage at full load. ## Electrical and thermal ratings Operating voltage is 750 V AC, three-phase, at 50 or 60 Hz. The DC-rated current is 343.1 A, which matters if the choke is used on the DC link rather than the AC line — a common substitution in some drive topologies, though the primary application is AC line-side commutation. Total power loss is 510 W: 300 W in the coil and 210 W in the iron core at rated conditions. That heat must be managed — the IP00 open-frame construction means no enclosure; it relies on free-air convection within the panel or cabinet. Ambient temperature rating is 40 °C, with Class H insulation (180 °C thermal class per IEC 60085), giving a generous thermal margin above the 40 °C ambient. ## Physical integration and connections Dimensions are 0.227 m deep, 0.35 m wide, and 0.321 m high — a substantial block, roughly 9 × 14 × 13 inches. It's an open-frame component meant for bolting into a cabinet floor or backplate, not DIN-rail mounted. Main circuit connections use flat-type terminals (flat connector), sized for lug or bus-bar termination typical of 250 A+ conductors.","metaTitle":"Siemens 4EU3622-6BA00-0AA0 Commutating Choke, 280A Max, 750V","metaDescription":"Siemens 4EU3622-6BA00-0AA0 commutating choke for converter drives.
