Hammond Power Solutions SG3A0045KK0C is a three-phase general duty transformer engineered for industrial power distribution, converting 480V delta primary input to 480Y/277V wye-n secondary output. This 45 kVA unit operates at 60Hz with a 150°C temperature rise and 220°C insulation class, housed in a Type 3R/IP24 enclosure with ANSI 61 grey finish. The transformer weighs 415 lb and measures 28.75 inches high by 25.75 inches wide by 23.8 inches deep, featuring mechanical lug terminations and a 45 dBA sound level. It complies with DOE 2016, NRCAN 2019, and NMX 2021 efficiency regulations, and meets OSHPD and IBC 2018 seismic requirements with Sds=2.0, z/h=1, and lp=1.5 parameters. Typical applications include commercial buildings, industrial facilities, and infrastructure projects requiring reliable three-phase power conversion.
