The VW3A4412 is an EMC radio interference input filter from the Schneider Altivar range, designed to sit on the line side of a variable-speed drive and suppress conducted emissions back onto the three-phase supply. It is rated for 728 A continuous current and dissipates 210 W of thermal losses at full load. The filter handles both 200-240 V and 380-500 V three-phase networks, with a maximum earth leakage current of 500 mA at 400 V 50 Hz. That leakage figure matters for sizing upstream RCDs or for installations where cumulative leakage from multiple drives could nuisance-trip a common residual-current device.
Schneider has classified this filter as obsolete. No official successor order code has been published, so a form-fit-function replacement must be evaluated case by case against the drive rating and the required attenuation band.
The filter is rated IP00 as shipped; IP30 is achievable with the optional VW3A9601 kit. Vibration resistance is 1 gn at 13-150 Hz and 1.5 mm peak-to-peak at 3-13 Hz per IEC 60068-2-6; shock resistance is 15 gn for 11 ms per IEC 60068-2-27. The filter is rated for 0-93 % relative humidity (non-condensing) per IEC 68-2-3.
Standards and tolerance
The filter is listed to EN 133200, a harmonized component standard for EMC filters. Tolerance is stated at 10 %, which typically applies to the capacitance values inside the filter stages and affects the cutoff frequency band.
