Hammond Power Solutions SG3A0015KK0C - 3-Phase Transformer 15kVA 480D-480Y/277V

SG3A0015KK0C

Hammond Power Solutions SG3A0015KK0C is a three-phase general duty transformer designed for industrial power distribution applications. This 15 kVA unit features a 480V delta primary connection with multiple 2.5% taps and delivers 480Y/277V secondary power through a wye configuration with neutral. The transformer is housed in a Type 3R/IP24 rated enclosure measuring 21.88 inches high by 21.5 inches wide by 20.12 inches deep, finished in ANSI 61 grey with UL50 certification. 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, z/h=1, and lp=1.5 parameters. Typical applications include commercial buildings, industrial facilities, and infrastructure projects requiring reliable three-phase power conversion with seismic resilience.
