Hammond Power Solutions SG3A0045BB0C - 3-Phase Transformer 45kVA 208D-208Y/120V

SG3A0045BB0C

Hammond Power Solutions SG3A0045BB0C is a three-phase general duty transformer designed for industrial power distribution applications. This 45 kVA unit operates at 60Hz with a 208V delta primary connection and provides 208Y/120V secondary output through wye-N configuration with mechanical lug terminations. The transformer features a Type 3R/IP24 rated enclosure with ANSI 61 grey finish, measuring 28.75 inches high by 25.75 inches wide by 23.8 inches deep, and maintains a low 45 dBA sound level. It complies with DOE 2016, NRCAN 2019, and NMX 2021 efficiency regulations while meeting OSHPD and IBC 2018 seismic requirements for Sds=2.0 applications. Typical applications include commercial buildings, industrial facilities, and infrastructure projects requiring reliable three-phase power conversion with seismic resilience.
