Hammond Power Solutions TX2A0075KHKF - 3-Phase Transformer 75kVA (480D-400Y/231V)

TX2A0075KHKF

Hammond Power Solutions TX2A0075KHKF is a three-phase transformer designed for industrial power distribution applications. This 75 kVA unit operates at 480V delta primary to 400Y/231V secondary wye-n configuration with 60Hz frequency, featuring copper windings and 115°C temperature rise with 180°C insulation class. The transformer is housed in a Type 4/IP66 rated enclosure with ANSI 61 grey finish, measuring 25.63" H × 32.38" W × 22" D, and produces minimal 55 dBA operational noise. It meets OSHPD and IBC 2018 seismic standards (Sds=2.0, z/h=1, lp=1.5) with 2-5% impedance and includes a single electrostatic shield with Dyn1 vector configuration. Typical applications include industrial facilities requiring reliable power conversion in general duty environments, including some hazardous locations and marine ABS duty applications.
