Hammond Power Solutions SK3A0015PK4K is a three-phase general duty transformer engineered for stepping down 600V delta primary power to 480Y/277V wye-N secondary in industrial and commercial power distribution systems. This 15 kVA unit operates at 60Hz with a 200 lb weight and features a Type 3R / IP24 rated enclosure finished in ANSI 61 grey, measuring 21.88 inches high by 21.5 inches wide by 20.12 inches deep. It complies with CSA and UL certifications, as well as DOE 2016, NRCAN 2019, and NMX 2021 efficiency standards, while meeting OSHPD and IBC 2018 seismic requirements for Sds=2.0 with lp=1.5 and z/h=1 parameters. Typical applications include industrial facilities, commercial buildings, and infrastructure projects requiring reliable three-phase power conversion with seismic resilience and quiet 45 dBA operation.
