The Schneider VW3A46101A is a passive input filter for the ATV610 variable speed drive family, sized for a 4 kW / 5 hp motor on a 380-480 V three-phase supply. It knocks line-side current harmonics down to 10 % THDI — that's the figure that matters for meeting IEEE 519 or utility-imposed distortion limits without oversizing the drive's DC bus or adding a separate active front end. One filter per drive, wired between the line and the drive input terminals /L2/L3.
Efficiency sits at 98 %, meaning about 75 W of thermal losses to vent inside the enclosure; that's manageable in a standard IP20 panel but worth checking if the cabinet is tightly packed or passively cooled. Supply voltage range is 380-480 V ±10 %, 50 Hz ±2 %. The 50 Hz tolerance is tight — if your site runs 60 Hz, this filter won't tune correctly. Three-phase only; no single-phase variant in this order code. Compliance carries UL 61800-5-1 and IEC 61800-5-1 — the adjustable-speed drive safety standard for electrical/thermal/energy hazards. That means the filter is recognized for use in UL-listed drive panels without additional component-level evaluation, as long as the installation follows the drive manual's wiring and clearance rules.
Terminals accept 0.5-6 mm² on the power path (/L2/L3 and '/L2'/L3'), with separate 1.5 mm² terminals for the DC choke connections (D1/D2/D3) and 0.5-4 mm² for the temperature-sensor pair (TS/TS'). The separate choke and sensor terminals mean you need to land those wires even if you're not using the drive's DC choke option — the filter expects them connected per the wiring diagram.
This is a mature, steady-state part, not a phase-out risk for a BOM freeze.
