The VW3A46109A is a passive harmonic filter designed for the Schneider ATV610 variable speed drive family, sized for a 37 kW / 50 hp motor load. Rated for 380-480 V three-phase, 50 Hz ±2 %, this filter handles 81 A on the output side and 54.7 A on the input side. The 81 A figure governs the motor-side current; the 54.7 A input rating reflects the lower line current after harmonic correction. Efficiency is 98 %, meaning 414 W of thermal losses must be ventilated out of the enclosure. The terminal block accepts 6-25 mm² on the line and load sides (/L2/L3 and '/L2'/L3'), with separate 6 mm² terminals for the DC bus choke connections (D1/D2/D3, D1'/D2'/D3') and 0.5-4 mm² for the thermal switch (TS/TS').
Standards and compliance — what UL 61800-5-1 covers
The filter carries UL 61800-5-1 and IEC 61800-5-1 certification, which covers adjustable-speed drive systems for electrical safety — thermal, dielectric, and short-circuit protection. Class N electrical insulation applies, per the listing.
