The VW3A58406 is an RFI filter designed for the Schneider Electric Altivar 58 series, specifically the ATV58HD28N4 drive. It suppresses electromagnetic interference on the drive's input power lines, helping the installation meet EMC emission limits.
The filter mounts inline between the mains supply and the ATV58HD28N4 drive input. It is sized for the drive's rated current and handles the conducted emissions profile typical of a variable-speed drive installation. Panel builders should verify physical fit within the existing enclosure, as the filter adds to the overall footprint.
