Hammond Power Solutions TN2A0075PBKF - 75 kVA Transformer 600V-208Y/120V

TN2A0075PBKF

Hammond Power Solutions TN2A0075PBKF is a three-phase transformer designed for general duty applications including some hazardous locations and marine ABS duty. This 75 kVA unit features a 600V delta primary configuration with multiple 2.5% FCAN and FCBN taps, stepping down to 208Y/120V wye-n secondary 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 25.63 inches high by 32.38 inches wide by 22 inches deep, and operates at 60Hz with 2-5% impedance while maintaining a sound level of 55dBA. It complies with seismic standards including OSHPD and IBC 2018 (Sds=2.0, z/h=1, lp=1.5) and features Dyn1 vector configuration with a single electrostatic shield. Typical applications include industrial power distribution systems requiring reliable voltage transformation in demanding environments. Key Features & Specifications
