Hammond Power Solutions TN2A0002QKKA - 3-Phase Transformer 2kVA 600/480V-480Y/277V

TN2A0002QKKA

Hammond Power Solutions TN2A0002QKKA is a three-phase transformer designed for general duty industrial power distribution with suitability for some hazardous locations and marine ABS duty. This 2 kVA unit features dual primary voltage inputs of 600V and 480V in delta configuration, delivering secondary output of 480Y/277V in wye-n configuration with copper windings rated for 80°C temperature rise and 130°C insulation class. The transformer is housed in a Type 4/IP66 rated enclosure with ANSI 61 grey finish, measuring 13.38×13.13×9.13 inches (340×334×232mm) and operating at 45dBA sound level with 2-6.5% impedance. 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 control systems, machinery power supplies, and commercial building electrical distribution where reliable voltage transformation is required.
