Hammond Power Solutions SK3A0030PK3K - 30 kVA Transformer 600V Delta/480Y/277V

SK3A0030PK3K

Hammond Power Solutions SK3A0030PK3K is a three-phase general duty transformer designed for industrial power distribution applications. This 30 kVA unit features a 600V delta primary connection with ±2.5% and ±5% voltage adjustment taps, stepping down to 480Y/277V wye secondary configuration with mechanical lug terminations. The transformer is housed in a Type 3R/IP24 rated enclosure measuring 28.75" H × 25.75" W × 23.8" D with ANSI 61 grey finish, operating at 60Hz with 150°C temperature rise and 220°C insulation class. 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 z/h=1 and lp=1.5. Typical applications include industrial facilities, commercial buildings, and infrastructure projects requiring reliable three-phase power conversion with seismic resilience.
