It sits between the supply and the drive rectifier, limiting harmonic distortion and reducing peak currents that stress the DC bus capacitors. Rated for 6.3 A at 400/480 V AC, 50/60 Hz, with a nominal inductance of 0.0022 H and a relative inductive voltage drop of 2% at rated current.
The 6.3 A AC maximum current and 5.67 A operational current define the continuous load it can carry. For a drive input, size the choke so its rated current equals or exceeds the drive's input current rating. Total power loss is 22.6 W (17 W coil + 5.6 W iron core) at rated conditions, thermal class B (130 °C rise). That loss is dissipated as heat inside the enclosure; the IP00 open-frame construction means it must be mounted in a clean, dry cabinet — no washdown, no dust, no condensation. Ambient temperature rated at 40 °C; above that, derate the current per the thermal curve in the datasheet. Screw-type and tab terminals accept ring lugs or fork terminals on the main circuit. Panel dimensions are 0.088 m wide × 0.108 m tall × 0.057 m deep.
