Hammond Power Solutions SG3A0150KK0C - 150 kVA Transformer 480D-480Y/277V

SG3A0150KK0C

Hammond Power Solutions SG3A0150KK0C is a three-phase general duty transformer designed for industrial power distribution applications. This 150 kVA unit features a 480V delta primary connection with multiple tap settings and delivers 480Y/277V secondary power through mechanical lug terminations. The transformer is housed in a Type 3R/IP24 rated enclosure measuring 44.5 inches high by 31.5 inches wide by 29.5 inches deep with ANSI 61 grey finish, operating with a 150°C temperature rise and 220°C insulation class. It complies with multiple efficiency standards including DOE 2016, NRCAN 2019, and NMX 2021, while meeting IBC 2018 seismic requirements for Sds=2.0 with z/h=1 and lp=1.5 parameters. Typical applications include industrial facilities, commercial buildings, and utility installations requiring reliable three-phase power conversion with Dyn1 vector configuration and low 50 dBA sound levels.
