RFI Filter for ATV58 Drive Lines
The Schneider Electric VW3A58407 is an RFI filter, Size 6, designed for use with ATV58 variable speed drives, excluding the ATV58H variant. Its function is to attenuate conducted electromagnetic interference on the drive's input power line, helping the installation meet EMC emission limits. For a Tier-1 line running multiple ATV58 drives on a common DC bus, this filter mounts at the line input of each drive or group to keep switching noise from coupling back into the plant power network.
This is Size 6 in the VW3A filter family, which corresponds to a specific mounting footprint and current rating for the ATV58 drive frame sizes it supports. Verify the drive model against the filter's compatibility list: it covers all ATV58 variants except the ATV58H. The filter connects between the line supply and the drive input terminals; typical panel integration involves DIN-rail or direct-panel mounting with the appropriate cable glands for the conductor cross-section.
