Hammond Power Solutions TE3A0020NGM - 3-Phase Transformer 20kVA 575D-380Y/220V

TE3A0020NGM

Hammond Power Solutions TE3A0020NGM 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 20 kVA capacity and operates at 60Hz frequency with 2.5%-6.5% impedance. The transformer is housed in a Type 3R/IP24 rated enclosure measuring 21.88"H x 21.5"W x 20.12"D with ANSI 61 grey finish, featuring 150°C temperature rise and 220°C insulation class. It complies with NRCAN 2019 efficiency standards and meets IBC 2018 seismic requirements (Sds=2.0, z/h=0, lp=1.5) while maintaining 45 dBA sound levels per NEMA ST-20. Typical applications include industrial machinery, manufacturing equipment, and commercial power systems requiring reliable voltage transformation with Dyn1 vector configuration and mechanical lug terminations.
