Hammond Power Solutions DM220KK is a three-phase general duty transformer engineered for industrial power distribution, providing reliable voltage transformation and isolation. It operates with a 480V delta primary connection and a 480Y/277V wye secondary configuration, supporting a 220 kVA rating at 60Hz with aluminum windings rated for a 150°C temperature rise and 220°C insulation class. The unit is housed in a Type 3R/IP24 enclosure with an ANSI 61 grey finish, measuring 41" H × 32" W × 25.5" D and weighing 1300 lb, and is certified to CSA and UL standards. It 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 requiring standard impedance of 3.5-6.5% and Dyn1 vector configuration for reliable power transformation.
