Hammond Power Solutions DM440NJC is a three-phase general duty transformer engineered for industrial power distribution, converting 575V delta primary input to 460Y/266V wye secondary output with a 440 kVA rating. The unit operates at 60 Hz with 4.5% to 7% impedance, a 150°C temperature rise, and 220°C insulation class, maintaining a sound level of 60 dBA per NEMA ST-20. Housed in a Type 3R/IP24 rated enclosure finished in ANSI 61 Grey, it measures 59 inches high by 48.5 inches wide by 38 inches deep and weighs 2500 lb. It is certified to CSA and UL standards, complies with IBC 2018 seismic requirements (Sds=2.0), and is approved for installation in US and LATAM markets. Typical applications include industrial machinery, manufacturing facilities, and commercial power systems requiring reliable three-phase power conversion.
