Hammond Power Solutions SK3A0015PK9K - 15 kVA Transformer 600V Delta to 480Y/277V

SK3A0015PK9K

Hammond Power Solutions SK3A0015PK9K is a three-phase general duty transformer designed for industrial power distribution applications. This 15 kVA unit features a 600V delta primary to 480Y/277V secondary configuration with 60Hz operation and meets DOE 2016, NRCAN 2019, and NMX 2021 efficiency regulations. The transformer is housed in a Type 3R/IP24 rated enclosure with ANSI 61 grey finish, measuring 21.88" H × 21.5" W × 20.12" D, and incorporates seismic compliance for OSHPD and IBC 2018 standards with Sds=2.0, z/h=1, and lp=1.5 parameters. With a temperature rise of 150°C, 220°C insulation class, 2.5%-6.5% impedance, and 45 dBA sound level, it's suitable for commercial buildings, industrial facilities, and infrastructure applications requiring reliable power transformation with seismic resilience.
