Hammond Power Solutions SK3A0075PK4K - 75 kVA Transformer 600V Delta/480Y/277V

SK3A0075PK4K

Hammond Power Solutions SK3A0075PK4K is a three-phase general duty transformer designed for industrial power distribution applications. This 75 kVA unit features a 600V delta primary and 480Y/277V wye secondary configuration operating at 60Hz frequency with a temperature rise of 150°C and 220°C insulation class. The transformer is housed in a Type 3R/IP24 rated enclosure with ANSI 61 grey finish, measuring 36 inches high by 28.25 inches wide by 27 inches deep, and produces minimal 50 dBA operational noise. It complies with DOE 2016, NRCAN 2019, and NMX 2021 efficiency regulations while meeting IBC 2018 seismic standards with Sds=2.0, z/h=1, and lp=1.5 parameters. Typical applications include industrial facilities, commercial buildings, and manufacturing plants requiring reliable three-phase power conversion. Key Features & Specifications
