Hammond Power Solutions SK3A0150PK9K is a three-phase general duty transformer engineered for industrial power distribution, converting 600V delta primary voltage to 480Y/277V secondary voltage. It delivers a 150 kVA rating at 60Hz with a 150°C temperature rise and 220°C insulation class, housed in a Type 3R/IP24 enclosure with ANSI 61 grey finish. The unit weighs 5.19 lb and measures 44.5 inches high by 31.5 inches wide by 29.5 inches deep, featuring mechanical lug terminations with 2x2.5% FCAN taps. It complies with CSA and UL certifications, DOE 2016, NRCAN 2019, and NMX 2021 efficiency regulations, and meets IBC 2018 seismic standards (Sds=2.0, z/h=1, lp=1.5). Typical applications include industrial facilities, commercial buildings, and manufacturing plants requiring reliable three-phase power conversion with a standard impedance range of 3% to 6.5% and Dyn1 vector configuration.
