Hammond Power Solutions SK3A0225PB4S - 3-Phase Transformer 225 kVA 600D-208Y/120V

SK3A0225PB4S

Hammond Power Solutions SK3A0225PB4S is a three-phase general duty transformer designed for industrial power distribution applications. This unit features a 600V delta primary and 208Y/120V wye secondary configuration with aluminum windings rated for 150°C temperature rise and 220°C insulation class. The transformer is housed in a Type 3R/IP24 enclosure with ANSI 61 grey finish, measuring 52"H × 37.5"W × 34"D, and operates at 60Hz with a sound level of 55 dBA. It complies with efficiency regulations including DOE 2016, NRCAN 2019, and NMX 2021, and meets IBC 2018 seismic standards (Sds=2.0, z/h=0, lp=1.5). Typical applications include industrial facilities, commercial buildings, and power distribution systems requiring reliable three-phase power conversion. Key Features & Specifications
