Hammond Power Solutions TE3A0020JJM is a three-phase general duty transformer designed for stepping down voltage in industrial power distribution systems. It operates with a 460V delta primary connection and a 460Y/266V wye-n secondary configuration, providing 20 kVA of capacity at 60Hz with a 150°C temperature rise and 220°C insulation class. The unit is housed in a Type 3R/IP24 rated enclosure with an ANSI 61 grey finish, measures 21.88 inches high by 21.5 inches wide by 20.12 inches deep, and weighs 225 lb, featuring 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 per NEMA ST-20. 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.
