TRANSFORMER, 14 KVA, 3 PH, 50/60 HZ, P/N 19879

This 14 kVA three-phase transformer is designed for reliable power distribution in industrial and commercial applications operating at 50/60 Hz. It features copper windings, which provide excellent conductivity and improved efficiency. As a result, the transformer delivers dependable performance in demanding environments.

The unit has a primary rating of 440/480 VAC line-to-line in a Wye configuration with a maximum current of 36.75 amps. In addition, the transformer includes two secondary outputs to support multiple voltage requirements.

Secondary A provides 208/230 VAC line-to-line in a Wye configuration with a maximum current of 27.75 amps, delivering up to 10 kVA. Additionally, it includes a 120 VAC line-to-neutral output for control circuits or auxiliary equipment.

Meanwhile, Secondary B delivers 440 VAC line-to-line in a Wye configuration with a current rating of 5.25 amps, providing 4 kVA. Because of this dual-secondary design, the transformer can power both lower- and higher-voltage loads.

Finally, the transformer is built as an open core and coil assembly, suitable for installation inside electrical panels or enclosures with proper ventilation. The unit measures approximately 14.5” W × 13” H × 15” D and has an estimated weight of 300 lbs.
