Hammond Power Solutions SH3U0045KB3S - 3-Phase Transformer 45kVA 480Y-208Z/120

SH3U0045KB3S

Hammond Power Solutions SH3U0045KB3S is a three-phase general duty transformer designed for industrial power distribution applications. The unit features a 480Y primary voltage configuration with wye connection and delivers 208Z/120 secondary voltage through zig-zag-n connection, operating at 60Hz frequency with a standard 45 kVA rating. Constructed with a Type 3R/IP24 rated enclosure measuring 36 inches in height, 28.25 inches in width, and 27 inches in depth, the transformer features ANSI 61 grey finish and mechanical lug terminations. It complies with multiple efficiency regulations including DOE 2016, NRCAN 2019, and NMX 2021, while meeting IBC 2018 seismic standards with Sds=2.0 rating and maintaining 48 dBA sound levels. Typical applications include commercial buildings, industrial facilities, and institutional power systems requiring reliable three-phase power conversion. Key Features & Specifications
