Hammond Power Solutions TE3A0275KKM - 3-Phase Transformer 275 kVA 480D-480Y/277V

TE3A0275KKM

Hammond Power Solutions TE3A0275KKM is a three-phase general duty transformer designed for industrial power distribution applications. This unit features a 480V delta primary configuration and delivers 480Y/277V secondary output with a 275 kVA capacity, operating at 60Hz frequency with standard impedance ranging from 3.5% to 7%. The transformer is housed in 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 incorporates a Dyn1 vector configuration with -30° phase shift. It complies with NRCAN 2019 efficiency regulations for Canada and meets IBC 2018 seismic standards (Sds=2.0, z/h=0, lp=1.5) while maintaining a sound level of 55 dBA per NEMA ST-20. Typical applications include industrial facilities, commercial buildings, and institutional settings requiring reliable three-phase power conversion with 150°C temperature rise and 220°C insulation class ratings.
