Hammond Power Solutions SG3C0045KD0C - 3-Phase Transformer 45kVA 480D-240/120V

SG3C0045KD0C

Hammond Power Solutions SG3C0045KD0C is a three-phase general duty transformer designed for industrial power distribution applications. This 45 kVA unit features a 480V delta primary configuration with multiple 2.5% taps and delivers 240/120V secondary output, operating at 60Hz frequency with standard impedance ranging from 2.5% to 6.5%. The transformer is housed in a Type 3R/IP24 rated enclosure measuring 28.75 inches high by 25.75 inches wide by 23.8 inches deep, finished in ANSI 61 grey with UL50 certification and mechanical lug secondary terminations. It complies with multiple efficiency standards including DOE 2016, NRCAN 2019, and NMX 2021, and meets seismic requirements for OSHPD and IBC 2018 with Sds=2.0, z/h=1, and lp=1.5 parameters. Typical applications include industrial facilities, commercial buildings, and infrastructure projects requiring reliable three-phase power conversion with seismic resilience and low 45 dBA sound levels.
