Hammond Power Solutions TE3A0075NN - 3-Phase Transformer 75 kVA 575V

TE3A0075NN

Hammond Power Solutions TE3A0075NN is a three-phase general duty transformer designed for industrial power distribution applications. It features a 575V delta primary configuration and delivers 575Y/332V secondary voltage through wye-N connection with 75 kVA capacity. The transformer is constructed with aluminum windings rated for 150°C temperature rise and 220°C insulation class, housed in a Type 3R/IP24 enclosure measuring 36" H × 28.25" W × 27" D with ANSI 61 grey finish. This unit complies with NRCAN 2019 efficiency standards and meets IBC 2018 seismic requirements (Sds=2.0, z/h=0, lp=1.5) while operating at 60Hz with 50 dBA sound levels. Typical applications include industrial facilities requiring reliable power conversion with Dyn1 vector configuration and standard 2.5%-6.5% impedance characteristics. Key Features & Specifications
