Hammond Power Solutions TE3A0440NN - Dry-Type Transformer 440 kVA (575V 3-Phase)

TE3A0440NN

Hammond Power Solutions TE3A0440NN is a three-phase transformer designed for industrial power distribution applications. This 440 kVA unit operates at 575V delta primary to 575Y/332V secondary with 60Hz frequency and features aluminum windings rated for 150°C temperature rise with 220°C insulation class. The transformer is housed in a Type 3R/IP24 enclosure with ANSI 61 grey finish, measuring 64"H x 49"W x 39"D, and incorporates a single electrostatic shield with Dyn1 vector configuration. It complies with NRCAN 2019 efficiency regulations and meets IBC 2018 seismic standards (Sds=2.0, z/h=0, lp=1.5) while maintaining 60 dBA sound levels per NEMA ST-20. Typical applications include manufacturing facilities, industrial plants, and commercial power systems requiring reliable voltage transformation with 4-7.5% impedance characteristics.
