Hammond Power Solutions TE3A0275NNM - 3-Phase Transformer 275kVA 575V Delta-Wye

TE3A0275NNM

Hammond Power Solutions TE3A0275NNM is a three-phase general duty transformer designed for industrial power distribution applications. This 275 kVA unit operates at 60Hz with primary voltage of 575V delta connection and secondary voltage of 575Y/332V wye-n configuration, featuring a temperature rise of 150°C and 220°C insulation class. The transformer is housed in a Type 3R/IP24 enclosure with ANSI 61 grey finish, measuring 44.5 inches high by 31.5 inches wide by 29.5 inches deep, and includes mechanical lug secondary terminations with a single electrostatic shield. It complies with NRCAN 2019 efficiency regulations and IBC 2018 seismic standards (Sds=2.0, z/h=0, lp=1.5), maintaining a sound level of 55 dBA per NEMA ST-20. This transformer is suitable for various industrial applications requiring reliable power conversion with standard impedance range of 3.5% to 7% and Dyn1 vector configuration.
