Hammond Power Solutions TE3A0051KGM - 3-Phase Transformer 51 kVA 480D-380Y/220V

TE3A0051KGM

Hammond Power Solutions TE3A0051KGM is a three-phase general duty transformer designed for industrial power distribution applications. The unit features a 480V delta primary configuration and delivers 380Y/220V secondary output with wye-N connection, operating at 60Hz frequency with 51 kVA capacity. Constructed with a Type 3R/IP24 rated enclosure finished in ANSI 61 grey, the transformer measures 28.75 inches in height, 25.75 inches in width, and 23.8 inches in depth, featuring mechanical lug terminations and a single electrostatic shield. The transformer complies with NRCAN 2019 efficiency regulations and meets IBC 2018 seismic standards (Sds=2.0, z/h=0, lp=1.5) while maintaining a 50 dBA sound level per NEMA ST-20. Typical applications include industrial machinery, manufacturing facilities, and commercial power systems requiring reliable voltage transformation with 150°C temperature rise and 220°C insulation class ratings.
