Hammond Power Solutions TE3A0440JJ - 3-Phase Transformer 440 kVA (460V Delta/Wye)

TE3A0440JJ

Hammond Power Solutions TE3A0440JJ is a three-phase general duty transformer designed for industrial power distribution applications. This 440 kVA unit features a 460V 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 64"H × 49"W × 39"D, and operates at 60 Hz with 4-7.5% impedance and 60 dBA sound level. It complies with NRCAN 2019 efficiency regulations and IBC 2018 seismic standards (Sds=2.0, z/h=0, lp=1.5), featuring Dyn1 vector configuration and electrostatic shielding. Typical applications include industrial plants, manufacturing facilities, and commercial power systems requiring reliable three-phase power transformation. Key Features & Specifications
