It carries a maximum current of 80A with a continuous rated current of 72A at 500V AC, 50 Hz. The 0.46 mH inductance limits harmonic distortion and reduces voltage notching on the drive input, which directly improves the power quality seen by upstream distribution equipment.
The 80A maximum and 72A rated current tell you this choke is sized for a drive with a nominal input current up to about 72A continuous, with headroom to 80A for short-duration overloads. The 4% relative inductive voltage drop (UK=4%) is typical for line reactors — enough to clean up harmonics without dropping excessive voltage across the choke under load. The 139W coil loss plus 42W iron core loss (181W total at rated current) must be dissipated; the IP00 enclosure means it is open-frame and relies on the panel's own airflow, so keep it clear of heat-sensitive components and allow at least 100mm clearance above and below for natural convection.
This is a panel-mount component, not DIN-rail. The flat-type terminals (flat connector) for the main circuit accept busbar or cable lugs — plan for a bolted connection, not a spring-cage or screw-clamp. The 0.225m width, 0.21m height, and 0.176m depth mean it occupies roughly the footprint of a small contactor but stands taller; verify the gland-plate clearance and side-wall spacing before laying out the backplate. Thermal class H insulation (IEC 60085) means the winding can handle 180°C hot-spot temperature, which is standard for drive-duty reactors.
