Commutating choke for converter duty
Rated inductance is 0.000074 H with a relative inductive voltage drop of 4% at rated current and frequency. The coil dissipates 280 W and the iron core 165 W at rated conditions, for a combined 445 W thermal loss that must be vented from the enclosure. Connections are via free cable endings, meaning the installer provides the ring lugs or ferrules.
Dimensions are 0.35 m wide by 0.321 m tall by 0.227 m deep. With IP00 and free cable endings, the choke is designed for bolted bus-bar or cable-lug connections inside a grounded metal enclosure. The total heat loss requires forced ventilation or a properly sized cabinet to keep internal ambient at or below the 40 °C rating.
