Hammond Power Solutions SH3U0015KB3S - 3-Phase Transformer 15kVA 480V-208V

SH3U0015KB3S

Hammond Power Solutions SH3U0015KB3S is a three-phase general duty transformer designed for industrial power distribution applications. It features a 480Y/277V primary with wye connection and 208Z/120V secondary with zig-zag-n configuration, delivering 15 kVA capacity with 60Hz frequency operation and standard impedance range of 2.5% to 6.5%. The transformer is housed in a Type 3R/IP24 rated enclosure with ANSI 61 grey finish, measuring 28.75" H × 25.75" W × 23.8" D, and operates with 150°C temperature rise and 220°C insulation class. It complies with DOE 2016, NRCAN 2019, and NMX 2021 efficiency regulations while meeting seismic standards including OSHPD and IBC 2018 with Sds=2.0, z/h=1, and lp=1.5 parameters. Typical applications include commercial buildings, industrial facilities, and electrical distribution systems requiring reliable three-phase power conversion with mechanical lug terminations and 45 dBA sound level operation.
