Hammond Power Solutions TE3A0330NG - 3-Phase Transformer 330 kVA (575D-380Y/220V)

TE3A0330NG

Hammond Power Solutions TE3A0330NG is a three-phase general duty transformer designed for industrial power distribution applications. This unit features a 575V delta primary configuration stepping down to 380Y/220V secondary with 330 kVA capacity and operates at 60Hz with 150°C temperature rise and 220°C insulation class. The transformer is constructed with aluminum windings and housed in a Type 3R/IP24 rated enclosure with ANSI 61 grey finish, measuring 52"H × 37.5"W × 34"D and producing 60 dBA maximum sound levels. It complies with NRCAN 2019 efficiency standards and meets IBC 2018 seismic requirements (Sds=2.0, z/h=0, lp=1.5) with 4-7.5% impedance and Dyn1 vector configuration. Typical applications include industrial machinery, manufacturing facilities, and commercial power systems requiring robust voltage transformation. Key Features & Specifications
