Hammond Power Solutions SH3U0045KB3K - 3-Phase Transformer 45kVA 480Y-208Z/120V

SH3U0045KB3K

Hammond Power Solutions SH3U0045KB3K is a three-phase general duty transformer designed for industrial power distribution applications. It features a 480Y primary voltage with wye connection and delivers 208Z/120 secondary voltage through zig-zag-n configuration, constructed with copper 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 28.75 inches high by 25.75 inches wide by 23.8 inches deep, and operates at 48 dBA sound level. It complies with DOE 2016, NRCAN 2019, and NMX 2021 efficiency regulations while meeting OSHPD and IBC 2018 seismic standards with Sds=2.0, z/h=1, and lp=1.5 parameters. Typical applications include commercial buildings, industrial facilities, and institutional power systems requiring reliable three-phase power conversion. Key Features & Specifications
