Hammond Power Solutions SG3A0015KB0C - 3-Phase Transformer 15kVA 480D-208Y/120V

SG3A0015KB0C

Hammond Power Solutions SG3A0015KB0C is a three-phase general duty transformer designed for industrial power distribution applications. This 15 kVA unit converts 480V delta primary voltage to 208Y/120V secondary voltage with a Dyn1 vector configuration and features multiple 2.5% full capacity above nameplate taps for voltage adjustment flexibility. The transformer is housed in a Type 3R/IP24 rated enclosure with ANSI 61 grey finish, measuring 21.88 inches high by 21.5 inches wide by 20.12 inches deep, and operates with a 150°C temperature rise using 220°C insulation class materials. It complies with DOE 2016, NRCAN 2019, and NMX 2021 efficiency regulations while meeting OSHPD and IBC 2018 seismic requirements for Sds=2.0 with 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 with seismic compliance.
