Hammond Power Solutions DM075JH - 3-Phase Transformer 75 kVA (460D-400Y/231V)

DM075JH

Hammond Power Solutions DM075JH is a three-phase general duty transformer designed for industrial power distribution applications. It features a 460V delta primary connection and delivers 400Y/231V secondary voltage through a wye-n configuration with 75 kVA capacity. The transformer is constructed with aluminum windings rated for 150°C temperature rise and 220°C insulation class, housed in a Type 3R/IP24 enclosure with ANSI 61 grey finish measuring 38x26x21 inches. It complies with IBC 2018 seismic standards (Sds=2.0, z/h=0, lp=1.5) and operates at 60Hz frequency with 50 dBA sound levels. This unit is suitable for industrial facilities requiring reliable power conversion with mechanical lug terminations and Dyn1 vector configuration. Key Features & Specifications
