FAQs
This unit is a three-phase 416 V primary transformer designed for 75 kVA with 208Y/120 V secondary. Plan for proper enclosure, space for the 28.22 in width and 48.56 in height, and the 23.42 in depth. Use 283L wiring connections and ensure adequate ventilation for a 150 °C rise rating. Consider WS19 weather shield if installed in exposed areas and verify the tap settings to compensate for voltage drop along feeders.
Key specs include 75 kVA three-phase, 60 Hz, primary 416 V, secondary 208Y/120 V, copper windings, frame 916A, and taps at 2 at +2.5% and 4 at -2.5%. It features an electrostatically shielded construction and a 150 °C rise with a 200 °C insulation system, supporting robust performance in demanding environments.
Yes. The transformer is described as a K-Factor nonlinear ventilated transformer, which is designed to mitigate harmonic effects from nonlinear loads. This makes it suitable for installations with drives and other non-linear equipment, helping maintain voltage integrity and reduce heating in downstream equipment.
