Hammond Power Solutions DM020NJ is a three-phase general duty transformer engineered for voltage conversion in industrial power distribution systems. This 20 kVA unit accepts a 575V delta primary connection and delivers a 460Y/266V secondary output, with a weight of 260 lb and aluminum windings rated for a 150°C temperature rise and 220°C insulation class. The transformer is housed in a Type 3R/IP24 enclosure with an ANSI 61 grey finish, measuring 28.75 inches high by 23.9 inches wide by 25 inches deep, and operates at a 45 dBA sound level with 3-6% impedance. It is certified to CSA and UL standards, complies with IBC 2018 seismic requirements (Sds=2.0, z/h=0, lp=1.5), and features a Dyn1 vector configuration. Typical applications include manufacturing facilities, commercial buildings, and industrial plants requiring reliable three-phase power transformation.
