Hammond Power Solutions SK3A0225PB9K - 3-Phase Transformer 225kVA 600D-208Y/120V

SK3A0225PB9K

Hammond Power Solutions SK3A0225PB9K is a three-phase general duty transformer designed for industrial power distribution applications. This 225 kVA unit features a 600V delta primary configuration with multiple 2.5% taps and delivers 208Y/120V secondary output through a wye-N connection with Dyn1 vector configuration. 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, finished in ANSI 61 grey with UL50 certification and featuring a 150°C temperature rise with 220°C insulation class. It complies with multiple efficiency regulations including DOE 2016, NRCAN 2019, and NMX 2021, and meets IBC 2018 seismic standards with Sds=2.0, z/h=1, and lp=1.5 parameters while operating at 55 dBA maximum sound level. Typical applications include industrial facilities, commercial buildings, and institutional power systems requiring reliable three-phase power conversion with standard enclosure protection.
