Hammond Power Solutions DM220JH - 3-Phase Transformer 220kVA 460D-400Y/231V

DM220JH

Hammond Power Solutions DM220JH is a three-phase general duty transformer designed for industrial power distribution applications. The unit features a 460V delta primary connection and delivers 400Y/231V secondary voltage through wye-N configuration with 220 kVA capacity. Constructed with aluminum windings and housed in a Type 3R/IP24 enclosure with ANSI 61 grey finish, the transformer operates with 150°C temperature rise and 220°C insulation class. Compliant with IBC 2018 seismic standards (Sds=2.0) and NEMA ST-20 sound level requirements at 55 dBA, this transformer is approved for installation in both US and LATAM markets. Typical applications include industrial facilities requiring reliable power conversion with standard impedance range of 3.5% to 6.5% and Dyn1 vector configuration. Key Features & Specifications
