This is a service-part kit, not a standalone drive — it contains the components needed to refurbish an existing ATV18 unit in the field. ## What to verify before ordering Because this is an exchange kit for a specific drive frame (ATV28HU09M2 and ATV28HU18M2), the fit depends on the exact drive model and revision in your panel. The kit is designed for the ATV18 series enclosure — if your drive is a later Altivar variant or a different frame size, this kit will not physically match. The ATV28HU09M2 is a 0.75 kW / 1 HP unit and the ATV28HU18M2 is a 1.5 kW / 2 HP unit, both 230 V single-phase input drives; the exchange kit contains the power board and control interface specific to those ratings.","metaTitle":"Schneider VW3A28821 ATV18 Exchange Kit, Obsolete","metaDescription":"Schneider VW3A28821 ATV18 exchange kit for ATV28HU09M2/ATV28HU18M2 drives.
