Hammond Power Solutions SK3A0015KK4K is a three-phase general duty transformer engineered for industrial and commercial power distribution applications requiring reliable voltage transformation. This 15 kVA unit converts a 480V delta primary connection to a 480Y/277V wye secondary configuration, operating at 60Hz with a 150°C temperature rise and 220°C insulation class. Housed in a Type 3R/IP24 rated enclosure with ANSI 61 grey finish, it measures 21.88 inches high by 21.5 inches wide by 20.12 inches deep and weighs 190 lb, featuring mechanical lug terminations and a single electrostatic shield. The transformer complies with DOE 2016, NRCAN 2019, and NMX 2021 efficiency regulations, and meets OSHPD and IBC 2018 seismic requirements with a 45 dBA sound rating. Typical applications include power distribution in commercial buildings, industrial facilities, and other settings requiring robust three-phase power transformation with seismic compliance.
