Hammond Power Solutions SK3A0015PK4K - 3-Phase Transformer 15kVA 600D/480Y

SK3A0015PK4K

Hammond Power Solutions SK3A0015PK4K is a three-phase general duty transformer designed for industrial power distribution applications. This unit features a 600V delta primary configuration with multiple voltage taps and delivers 480Y/277V secondary power through a wye-N connection, operating at 60Hz frequency with a 15 kVA capacity. 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 and mechanical lug terminations. It complies with DOE 2016, NRCAN 2019, and NMX 2021 efficiency regulations 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 45 dBA quiet operation.
