Hammond Power Solutions TE3A0145JJM - 3-Phase Transformer 145kVA 460V Delta-Wye

TE3A0145JJM

Hammond Power Solutions TE3A0145JJM is a three-phase transformer designed for general duty industrial power distribution applications. This 145 kVA unit operates at 60Hz with a 460V delta primary connection and delivers 460Y/266V through a wye-secondary configuration with mechanical lug terminations. The transformer features a Type 3R/IP24 rated enclosure with ANSI 61 grey finish, measuring 44.5 inches in height, 31.5 inches in width, and 29.5 inches in depth, and maintains a low 50 dBA sound level. It complies with NRCAN 2019 efficiency regulations and meets IBC 2018 seismic standards (Sds=2.0, z/h=0, lp=1.5) with 150°C temperature rise and 220°C insulation class. Typical applications include industrial facilities requiring reliable power transformation with standard impedance ranges of 2.5% to 6.5% and Dyn1 vector configuration. Key Features & Specifications
