Hammond Power Solutions DM034KDCN - 3-Phase Transformer 34kVA 480D-240Y/139V

DM034KDCN

Hammond Power Solutions DM034KDCN is a three-phase general duty transformer designed for industrial power distribution applications. It features a 480V delta primary configuration with dual 5% taps and delivers 240Y/139V secondary voltage through a wye-N connection with mechanical lug terminations. The transformer is housed in a Type 3R/IP24 rated enclosure with ANSI 61 grey finish, measuring 28.75 inches high by 23.9 inches wide by 25 inches deep, and operates with a 130°C temperature rise using 200°C insulation class materials. It complies with IBC 2018 seismic standards (Sds=2.0, z/h=0, lp=1.5) and NEMA ST-20 sound level requirements at 45 dBA, while being approved for installation in both US and LATAM markets. Typical applications include industrial facilities, manufacturing plants, and commercial buildings requiring reliable three-phase power conversion. Key Features & Specifications
