Hammond Power Solutions TE3A0020JJM - 3-Phase Transformer 20kVA 460V Delta-Wye

TE3A0020JJM

Hammond Power Solutions TE3A0020JJM is a three-phase general duty transformer designed for industrial power distribution applications. This 20 kVA unit features a 460V delta primary connection and 460Y/266V wye-n secondary configuration operating at 60Hz frequency with 150°C temperature rise and 220°C insulation class. The transformer is housed in a Type 3R/IP24 rated enclosure with ANSI 61 grey finish, measuring 21.88 inches high by 21.5 inches wide by 20.12 inches deep, and features mechanical lug secondary terminations with a single electrostatic shield. It complies with NRCAN 2019 efficiency regulations and meets IBC 2018 seismic standards (Sds=2.0, z/h=0, lp=1.5) while maintaining a low 45 dBA sound level. Typical applications include industrial facilities, manufacturing plants, and commercial buildings requiring reliable three-phase power transformation with Dyn1 vector configuration and standard 2.5%-6.5% impedance characteristics.
