Hammond Power Solutions DM075KKS is a three-phase general duty transformer engineered for industrial power distribution and commercial building applications. It converts a 480V delta primary to a 480Y/277V wye secondary, delivering 75 kVA of capacity at 60Hz with a standard 3-6% impedance range. The unit weighs 540 lb and is housed in a Type 3R / IP24 enclosure with an ANSI 61 grey finish, measuring 38 inches high by 26 inches wide by 21 inches deep, featuring aluminum windings rated for a 150°C temperature rise and 220°C insulation class. It complies with CSA and UL certifications, meets IBC 2018 seismic standards (Sds=2.0, z/h=0, lp=1.5), and operates at a sound level of 50 dBA per NEMA ST-20. Typical applications include power distribution in commercial buildings, industrial facilities, and other settings requiring reliable voltage transformation with a Dyn1 vector configuration and mechanical lug terminations.
