Hammond Power Solutions SK3A0150PK9K - 150 kVA Transformer 600D-480Y/277V

SK3A0150PK9K

Hammond Power Solutions SK3A0150PK9K is a three-phase general duty transformer designed for industrial power distribution applications. This unit features a 600V delta primary configuration stepping down to 480Y/277V secondary with a 150 kVA rating and 60Hz frequency, operating with a temperature rise of 150°C and 220°C insulation class. The transformer is housed in a Type 3R/IP24 enclosure with ANSI 61 grey finish, measuring 44.5 inches high by 31.5 inches wide by 29.5 inches deep, and includes mechanical lug terminations with 2x2.5% FCAN taps. It complies with DOE 2016, NRCAN 2019, and NMX 2021 efficiency regulations while meeting IBC 2018 seismic standards (Sds=2.0, z/h=1, lp=1.5) and maintaining a 50 dBA sound level. Typical applications include industrial facilities, commercial buildings, and manufacturing plants requiring reliable three-phase power conversion with standard impedance range of 3% to 6.5% and Dyn1 vector configuration.
