It smooths current harmonics and limits inrush, protecting both the drive and the upstream supply. Rated for 480 V AC at 50/60 Hz, it carries a maximum current of 91 A and a rated operational current of 81.9 A — the 91 A figure is the thermal limit at 40 °C ambient; the 81.9 A is the continuous duty point at rated voltage and frequency. The 0.16 mH inductance (160 µH) with a 4% relative inductive voltage drop means this choke is sized for a typical drive input where you want around 2–4% impedance. That's the sweet spot for reducing harmonic distortion without dropping too much voltage across the reactor under load.
IP00 open-frame construction — no enclosure, no finger-safe cover. This choke mounts inside a panel or cabinet, not in a wet or dusty location. Dimensions are 0.219 m wide by 0.179 m tall by 0.143 m deep, so it needs a decent chunk of backplate real estate. Terminals are flat-type connectors (busbar or ring-lug friendly), not screw-clamp blocks. Total power loss is 99.5 W (78 W copper + 21.5 W iron core). That heat has to leave the cabinet — factor it into your ventilation or forced-air cooling budget. Thermal class B (130 °C rise) per IEC 60085 gives you a standard insulation system; no exotic derating needed unless ambient exceeds 40 °C.
Compliance documentation: the title notes UL/CSA recognition and EN 61558-2-20 (safety of transformers, reactors, and power supply units). Expect a declaration of conformity covering the Low Voltage Directive and applicable harmonized standards. RoHS and REACH declarations should be available on request.
