What It Does & Where It Fits
The VW3SKLN006H010 is a 3-phase line choke from the Schneider Altivar range, designed to reduce current harmonics on the input side of a variable speed drive. With a rated current of 6 A and inductance of 10 mH, it smooths the current waveform drawn by the drive, lowering total harmonic distortion (THD) and meeting power-quality requirements before the drive's DC bus. It operates on 50...60 Hz supply frequencies.
Integration Note
Mounts in the drive's incoming line path — typically between the mains disconnection point and the drive input terminals. The 6 A rating matches small-frame Altivar drives in the 2.2–4 kW range on 400 V three-phase. Check physical dimensions against enclosure gland-plate space; line chokes run warm under load, so allow natural convection clearance above and below the core.
