FU). It smooths current harmonics, limits inrush current, and protects the drive rectifier from line transients. Rated for 500 V AC at 50 Hz with a rated current of 41 A (maximum 45 A) and an inductance of 0.81 mH, it produces a 4% relative inductive voltage drop at rated conditions — a typical value for drive input chokes that balances harmonic mitigation against voltage sag.
The 41 A rated current (45 A maximum) sets the continuous load capacity. For a 3-phase drive, this choke is typically sized for a drive with a rated input current at or below 41 A — check the drive's nameplate input amps, not the motor full-load amps. The 0.81 mH inductance and 4% voltage drop are a matched pair: higher inductance gives more harmonic attenuation but steals more voltage from the drive's DC bus. At 4%, this choke is in the standard range for general-purpose drive protection. The 77.4 W copper loss plus 25 W iron-core loss (total ~102 W at rated load) means it sheds heat; mount it with clearance for airflow — IP00 means no enclosure, so it goes inside a panel or cabinet, not in a washdown zone.
Physical integration
Dimensions are 0.219 m wide by 0.179 m tall by 0.143 m deep. The IP00 rating means it's open-frame — no drip shield, no finger-safe enclosure. Mount it inside a cabinet with at least 50 mm clearance on all sides for convection cooling. The thermal class B insulation (130 °C rise) per IEC 60085 gives headroom for the 40 °C ambient rating.
