Hammond Power Solutions DM330NJ - 3-Phase Transformer 330kVA 575D-460Y/266V

DM330NJ

Hammond Power Solutions DM330NJ is a three-phase general duty transformer designed for industrial power distribution applications. This 330 kVA unit features a 575V delta primary connection with ±5% voltage adjustment capability and delivers 460Y/266V secondary output through wye-N configuration. 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 measuring 51.5"H × 39.5"W × 34"D with ANSI 61 grey finish. The unit complies with IBC 2018 seismic standards (Sds=2.0) and operates at 60 dBA sound level with 4.5-7% impedance, making it suitable for manufacturing facilities, industrial plants, and commercial power systems requiring reliable voltage transformation.
