Hammond Power Solutions SK3A0750KK9K is a three-phase, 750 kVA general duty transformer engineered for stepping down 480V delta primary power to a 480Y/277V wye secondary configuration in industrial and commercial power distribution systems. This 60Hz unit features a 4-7.5% impedance range, a 150°C temperature rise, and 220°C insulation class, housed in a Type 3R/IP24 enclosure with an ANSI 61 grey finish and dimensions of 64"H x 49"W x 39"D. Weighing 4220 lb, the transformer complies with DOE 2016, NRCAN 2019, and NMX 2021 efficiency standards, and meets IBC 2018 seismic requirements with Sds=2.0, z/h=0, and lp=1.5 parameters, while maintaining a sound level of 64 dBA. It is certified to CSA and UL standards, making it suitable for industrial facilities, commercial buildings, and power distribution systems requiring reliable three-phase power transformation.
