Hammond Power Solutions TE3A0020NJ - 3-Phase Transformer 20kVA 575D/460Y

TE3A0020NJ

Hammond Power Solutions TE3A0020NJ is a three-phase general duty transformer designed for industrial power distribution applications. This 20 kVA unit features a 575V delta primary connection and 460Y/266V wye-n secondary configuration with aluminum windings rated for 150°C temperature rise and 220°C insulation class. The transformer is housed in a Type 3R/IP24 enclosure with ANSI 61 grey finish, measuring 21.88 inches high by 21.5 inches wide by 20.12 inches deep, and operates at 45 dBA sound level with mechanical lug secondary terminations. It complies with NRCAN 2019 efficiency regulations and meets IBC 2018 seismic standards (Sds=2.0, z/h=0, lp=1.5) for reliable performance in demanding environments. Typical applications include industrial facilities, manufacturing plants, and commercial buildings requiring robust power conversion with 2.5% to 6.5% impedance characteristics.
