Hammond Power Solutions SK3A0015KB3S - 3-Phase Transformer 15kVA 480D-208Y/120V

SK3A0015KB3S

Hammond Power Solutions SK3A0015KB3S is a three-phase general duty transformer designed for industrial power distribution applications. It features a 480V delta primary connection and provides 208Y/120V secondary output with 15 kVA capacity, constructed with aluminum windings rated for 150°C temperature rise and 220°C insulation class. The transformer is housed in a Type 3R/IP24 enclosure with ANSI 61 grey finish, measuring 21.88 inches high by 21.5 inches wide by 20.12 inches deep, and operates at 45 dBA sound levels. It complies with DOE 2016, NRCAN 2019, and NMX 2021 efficiency regulations while meeting OSHPD and IBC 2018 seismic requirements for high seismic zones. Typical applications include commercial buildings, industrial facilities, and infrastructure projects requiring reliable three-phase power conversion with seismic certification.
