Hammond Power Solutions DM275NJ - 3-Phase Transformer 275kVA 575D-460Y/266V

DM275NJ

Hammond Power Solutions DM275NJ is a three-phase general duty transformer designed for industrial power distribution applications. The unit features a 575V delta primary configuration with ±5% voltage adjustment capability and delivers 460Y/266V secondary output through wye-N connection at 275 kVA capacity. Constructed with aluminum windings rated for 150°C temperature rise and 220°C insulation class, the transformer is housed in a Type 3R/IP24 enclosure with ANSI 61 grey finish measuring 51.5 inches high by 39.5 inches wide by 34 inches deep. The design complies with IBC 2018 seismic standards (Sds=2.0, lp=1.5) and operates at 55 dBA sound levels while being approved for installation in both US and LATAM markets. Typical applications include industrial facilities requiring reliable power conversion from 575V delta to 480Y/277V systems for motor loads, lighting, and process equipment.
