Hammond Power Solutions TE3A0660JJM - 3-Phase Transformer 660 kVA (460D-460Y/266V)

TE3A0660JJM

Hammond Power Solutions TE3A0660JJM is a three-phase general duty transformer designed for industrial power distribution applications. The unit operates at 460V delta primary to 460Y/266V secondary wye-n configuration with a 660 kVA capacity and features a standard impedance range of 4% to 7.5%. Its robust Type 3R/IP24 enclosure with ANSI 61 grey finish measures 64" H × 49" W × 39" D and provides protection against weather elements while maintaining a sound level of 62 dBA. The transformer complies with NRCAN 2019 efficiency regulations and meets IBC 2018 seismic standards (Sds=2.0, z/h=0, lp=1.5) for enhanced structural reliability. Typical applications include industrial plants, manufacturing facilities, and commercial power systems requiring reliable voltage transformation with Dyn1 vector configuration.
