Hammond Power Solutions SH3U0500KB3K - 3-Phase Transformer 500kVA 480Y-208Z/120V

SH3U0500KB3K

Hammond Power Solutions SH3U0500KB3K is a three-phase transformer designed for industrial power distribution applications. This 500 kVA unit 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 64 inches high by 49 inches wide by 39 inches deep, and operates at 63 dBA sound levels. It complies with DOE 2016, NRCAN 2019, and NMX 2021 efficiency regulations while meeting IBC 2018 seismic standards with Sds=2.0, z/h=0, and lp=1.5 parameters. Typical applications include commercial buildings, manufacturing facilities, and industrial plants requiring reliable three-phase power conversion. Key Features & Specifications
