Hammond Power Solutions TN2A0150QKKF - 150 kVA Transformer 600/480V-480Y/277V

TN2A0150QKKF

Hammond Power Solutions TN2A0150QKKF is a three-phase transformer designed for industrial power distribution applications. This 150 kVA unit features dual primary voltage capability of 600V and 480V delta configuration with secondary output of 480Y/277V wye connection, constructed with copper windings rated for 115°C temperature rise and 180°C insulation class. The transformer is housed in a Type 4/IP66 rated enclosure with ANSI 61 grey finish, measuring 31.38" H × 36.63" W × 30.5" D, and operates at 60Hz with 2-5% impedance and sound levels below 55 dBA. It meets OSHPD and IBC 2018 seismic standards (Sds=2.0, z/h=1, lp=1.5) with UL50 enclosure certification for general duty applications including hazardous locations and marine ABS duty. Typical applications include industrial plants, commercial facilities, and environments requiring robust power conversion with seismic compliance. Key Features & Specifications
