Hammond Power Solutions TE3A0660JC - 3-Phase Transformer 660 kVA (460D-230Y/133V)

TE3A0660JC

The Hammond Power Solutions TE3A0660JC is a three-phase general duty transformer designed for industrial power distribution applications. It features a 460V delta primary configuration with ±5% voltage adjustment capability and delivers 230Y/133V secondary output through its wye-N connection at 660 kVA capacity. Constructed 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 72" H × 54" W × 44" D. The unit complies with NRCAN 2019 efficiency regulations and IBC 2018 seismic standards (Sds=2.0, z/h=0, lp=1.5), while operating at 62 dBA sound levels with 4-7.5% impedance. This transformer is suitable for industrial facilities, manufacturing plants, and commercial power systems requiring reliable voltage transformation with seismic resilience.
