Hammond Power Solutions TN2A0075KBKF - 75 kVA Transformer 480V-208Y/120V

TN2A0075KBKF

Hammond Power Solutions TN2A0075KBKF is a three-phase transformer designed for industrial power distribution applications. This 75 kVA unit features a 480V delta primary connection with multiple 2.5% FCAN and FCBN taps, stepping down to 208Y/120V secondary with wye-N configuration for versatile load distribution. Constructed with copper windings rated for 115°C temperature rise and 180°C insulation class, the transformer is housed in a Type 4/IP66 enclosure measuring 25.63×32.38×22 inches with ANSI 61 grey finish for harsh environment protection. The unit meets OSHPD and IBC 2018 seismic standards (Sds=2.0, z/h=1, lp=1.5) and operates at 55 dBA sound levels per NEMA ST-20. Typical applications include industrial facilities, marine installations, and locations requiring hazardous duty compliance with 2-5% impedance characteristics. Key Features & Specifications
