Hammond Power Solutions SK3A0750PB4S - 750 kVA Transformer 600V Delta/208Y120V Wye

SK3A0750PB4S

Hammond Power Solutions SK3A0750PB4S is a three-phase general duty transformer designed for industrial power distribution applications. This 750 kVA unit features a 600V delta primary and 208Y/120V wye secondary configuration with aluminum windings rated for 150°C temperature rise and 220°C insulation class. The transformer is housed in a Type 3R/IP24 enclosure with ANSI 61 grey finish, measuring 72" H × 54" W × 44" D, and operates at 64 dBA sound levels. 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). Typical applications include industrial plants, commercial facilities, and institutional buildings requiring robust power conversion with 4-7.5% impedance characteristics.
