Hammond Power Solutions SK3A0500PB3K - 3-Phase Transformer 500kVA 600D-208Y/120V

SK3A0500PB3K

Hammond Power Solutions SK3A0500PB3K is a three-phase general duty transformer designed for industrial power distribution applications. This 500 kVA unit features a 600V delta primary and 208Y/120V wye secondary configuration with 60Hz frequency operation, delivering reliable voltage transformation with 4-7.5% impedance. The transformer is housed in a Type 3R/IP24 enclosure with ANSI 61 grey finish, measuring 64"H x 49"W x 39"D, and incorporates a single electrostatic shield with 150°C temperature rise and 220°C insulation class. It complies with DOE 2016, NRCAN 2019, and NMX 2021 efficiency regulations while meeting IBC 2018 seismic standards (Sds=2.0, z/h=0, lp=1.5) and maintaining 63 dBA sound levels. Typical applications include industrial plants, commercial facilities, and institutional buildings requiring robust power distribution with wye secondary configurations for 120V loads.
