Mains Choke for Variable Frequency Drives
It's rated for 480V AC at 50/60 Hz with a maximum continuous current of 80A and an operational current of 72A per the datasheet conditions. The 0.18mH inductance with a 2% relative inductive voltage drop means it's sized to limit harmonic distortion and reduce dv/dt stress on the drive's input rectifier — a common requirement when the supply impedance is low or multiple drives share a bus.
The 80A maximum current and 72A operational rating tell you this choke can handle a 75–80A VFD input continuously at 40°C ambient. The 2% voltage drop is typical for a 2% impedance line reactor — enough to clean up harmonics without dropping excessive voltage under load. The IP00 enclosure means it's open-frame; mount it inside a panel or enclosure that provides the physical and electrical protection. The flat-type terminals accept bus bar or crimp lugs — not screw-clamp wire connectors, so plan your termination method before panel assembly.
Thermal and Loss Considerations
Total power loss at rated conditions is 83.1W — 64.8W in the coil plus 18.3W in the iron core. That's the heat you need to extract from the enclosure; at 40°C ambient, the thermal class B insulation per IEC 60085 gives a 130°C hot-spot limit. The 0.123m depth, 0.219m width, and 0.179m height (–) define the mounting footprint — allow clearance around the open core for airflow.
