The VW3A28401 is an RFI suppression filter for single-phase drives. It attenuates conducted EMI between the line supply and the drive input. Rated at 10 A nominal current with 100 mA earth leakage, the filter handles the input draw of those small drives while keeping leakage within typical panel limits for single-phase installations. The 8 W thermal losses mean it dissipates that heat into the enclosure — factor it into your cabinet thermal budget if the drive is already near its ambient limit.
The 10 A nominal current matches the input rating of the listed drives. The 100 mA earth leakage is typical for a single-phase RFI stage. Maximum cable distance between the filter and the drive is 50 m. That is generous for most panel-to-motor runs, but if your layout puts the drive further out, you will need to relocate the filter closer or add a second stage.
