Hammond Power Solutions DM020NNCN - 3-Phase Transformer 20kVA 575V Delta-Wye

DM020NNCN

Hammond Power Solutions DM020NNCN is a three-phase transformer designed for general duty industrial power distribution applications. This 20 kVA unit operates at 60Hz with primary voltage of 575V delta and secondary voltage of 575Y/332V wye configuration, featuring a standard impedance range of 3-6% and temperature rise of 130°C with 200°C insulation class. The transformer is housed in a Type 3R/IP24 rated enclosure with ANSI 61 grey finish, measuring 731mm high × 608mm wide × 635mm deep, and operates at a sound level of 45 dBA. It complies with IBC 2018 seismic standards (Sds=2.0, z/h=0, lp=1.5) and is approved for installation in both US and LATAM markets. Typical applications include industrial facilities requiring reliable power transformation with Dyn1 vector configuration and mechanical lug terminations for secure secondary connections.
