Hammond Power Solutions DM220NNC - 3-Phase Transformer 220 kVA (575V Delta-Wye)

DM220NNC

Hammond Power Solutions DM220NNC is a three-phase general duty transformer designed for industrial power distribution applications. The unit features a 575V delta primary connection with ±5% voltage adjustment capability and delivers 575Y/332V secondary output through a wye-N configuration with 220 kVA capacity. Constructed with a Type 3R/IP24 rated enclosure finished in ANSI 61 Grey, the transformer measures 41 inches high by 32 inches wide by 25.5 inches deep and operates with a 150°C temperature rise using 220°C insulation class materials. The transformer complies with IBC 2018 seismic standards (Sds=2.0, z/h=0, lp=1.5) and NEMA ST-20 sound level requirements of 55 dBA, making it suitable for industrial facilities, manufacturing plants, and commercial power systems requiring reliable three-phase power conversion.
