Hammond Power Solutions SH3U0075KB3S - 3-Phase Transformer 75kVA (480Y-208Z/120)

SH3U0075KB3S

Hammond Power Solutions SH3U0075KB3S is a three-phase general duty transformer designed for industrial power distribution applications. This 75 kVA unit features a 480Y primary voltage with wye connection and delivers 208Z/120 secondary voltage through zig-zag-n configuration, operating at 60Hz frequency with 150°C temperature rise and 220°C insulation class. The transformer is housed in a Type 3R/IP24 rated enclosure measuring 36 inches high by 28.25 inches wide by 27 inches deep, finished in ANSI 61 grey with UL50 certification and mechanical lug secondary terminations. It complies with multiple efficiency regulations including DOE 2016, NRCAN 2019, and NMX 2021, meeting IBC 2018 seismic standards with Sds=2.0, z/h=1, and lp=1.5 parameters while maintaining a 53 dBA sound level. Typical applications include commercial buildings, manufacturing facilities, and industrial plants requiring reliable three-phase power conversion with standard impedance range of 2.5% to 6.5%.
