Hammond Power Solutions DM275KDC is a three-phase general duty transformer engineered for industrial power distribution, converting 480V delta primary input to 240Y/139V wye-N secondary output. Rated at 275 kVA with a 60Hz frequency, it features ±5% FCAN/FCBN primary taps, standard 4-7% impedance, a 150°C temperature rise, and 220°C insulation class. The unit is housed in a Type 3R/IP24 enclosure finished in ANSI 61 grey, measuring 51.5 inches in height, 39.5 inches in width, and 34 inches in depth, with a weight of 1650 lb and an operating sound level of 55 dBA. It is certified to CSA and UL standards, complies with IBC 2018 seismic requirements (Sds=2.0, z/h=0, lp=1.5), and is approved for installation in US and LATAM markets. Typical applications include industrial facilities, manufacturing plants, and commercial power systems requiring reliable three-phase power transformation.
