Description
The Eaton 30 kVA general purpose ventilated transformer is engineered for reliable, energy-efficient power distribution in commercial and industrial environments. Designed with aluminum windings and compliant with DOE 2016 efficiency standards, this three-phase dry-type transformer delivers consistent voltage transformation from 480V delta to 400Y/231V.
Its NEMA 2 enclosure with fungus-proof protection ensures durability in demanding indoor conditions, while the ventilated design supports optimal thermal performance. Flexible installation options allow for floor or wall mounting in an upright configuration, making it ideal for facilities requiring dependable power conversion with minimal maintenance.
Built to meet UL standards and NEMA sound level requirements, this transformer is a robust solution for mission-critical applications where performance, efficiency, and longevity are essential.
