Hammond Power Solutions SK3A0015KK3K - 15 kVA Transformer 480D-480Y/277V

SK3A0015KK3K

Hammond Power Solutions SK3A0015KK3K is a three-phase transformer designed for industrial power distribution applications. This 15 kVA unit operates at 480V delta primary to 480Y/277V secondary with 60Hz frequency and features a 150°C temperature rise with 220°C insulation class. The transformer is housed in a Type 3R/IP24 enclosure measuring 21.88" H × 21.5" W × 20.12" D with ANSI 61 grey finish and mechanical lug terminations. It complies with DOE 2016, NRCAN 2019, and NMX 2021 efficiency regulations while meeting seismic standards including OSHPD and IBC 2018 with Sds=2.0. Typical applications include commercial buildings, industrial facilities, and infrastructure projects requiring reliable power conversion with 45 dBA sound levels and 2.5%-6.5% impedance characteristics.
