It is now listed as obsolete by Schneider Electric. Compatibility is confirmed with the ATV28 drive models: ATV28EU72M2, ATV28EU72N4, ATV28EU54N4, ATV28HU72M2, ATV28HU54M2, ATV28HU54N4, ATV28HU72N4, ATV28HU41N4, ATV28EU41N4, and ATV28EU54M2. ## Thermal and leakage — panel design constraints The filter dissipates 12 W of thermal losses — this heat must be accounted for in the enclosure ventilation or cooling budget to keep ambient within the drive's rating. Earth leakage current is 350 mA, which affects residual-current device (RCD) selection upstream; a Type B or time-delayed RCD is typically required to avoid nuisance tripping. Maximum cable distance between the drive and motor is 50 m with this filter in the circuit — longer runs may require output reactors or derating. ## Sourcing reality — obsolete, no direct replacement Schneider Electric has marked the VW3A28405 as obsolete. Availability is through independent surplus and broker channels. For a BOM freeze or a new design, a functionally equivalent RFI filter from the current Altivar range should be evaluated, but a pin-compatible drop-in replacement from Schneider is not documented.","metaTitle":"Schneider VW3A28405 RFI Filter, 22 A","metaDescription":"Schneider Electric VW3A28405 RFI filter for ATV28 drives. 22 A nominal, 12 W losses, 350 mA leakage.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Motor Control Accessories"],"specifications":{"Thermal losses":"12 W","lifecycle_stage":"mature","Speed drive name":"ATV28EU72M2 ATV28EU72N4 ATV28EU54N4 ATV28HU72M2 ATV28HU54M2 ATV28HU54N4 ATV28HU72N4 ATV28HU41N4 ATV28EU41N4 ATV28EU54M2","Earth leakage current":"350 mA","Filter nominal current":"22 A","Network number of phases":"Three phase","Maximum cable distance between devices":"50 m"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$630.07","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":"https://www.se.com/th/en/product/VW3A28405/rfi-filter-u54-u72m2-u41-u54-u72n4/","alternativesUrl":"https://aoctrl.com/api/mcp/products/VW3A28405/alternatives.json"},"ai":{"faq":[{"question":"What drives is the VW3A28405 RFI filter compatible with?","answer":"It is designed for the ATV28 series, specifically models ATV28EU72M2, ATV28EU72N4, ATV28EU54N4, ATV28HU72M2, ATV28HU54M2, ATV28HU54N4, ATV28HU72N4, ATV28HU41N4, ATV28EU41N4, and ATV28EU54M2."},{"question":"What are the key electrical ratings of VW3A28405?","answer":"Nominal current is 22 A, thermal losses are 12 W, and earth leakage current is 350 mA.
