Hammond Power Solutions DM051NNC is a three-phase general duty transformer engineered for industrial power distribution, providing reliable voltage conversion and isolation. It operates with a primary voltage of 575V delta and a secondary voltage of 575Y/332V wye-n, supporting a 51 kVA capacity at 60Hz. The unit is housed in a Type 3R/IP24 enclosure with an ANSI 61 grey finish, weighing 405 lb and measuring 28.75 inches high by 23.9 inches wide by 25 inches deep, featuring a 150°C temperature rise and 220°C insulation class. It is certified to CSA and UL standards, and complies with IBC 2018 seismic requirements (Sds=2.0, z/h=0, lp=1.5). Typical applications include industrial facilities requiring robust power conversion with mechanical lug terminations and a standard impedance range of 3-6%.
