FAQs
The V29R48F49CUNV uses an indoor-outdoor rated NEMA 3R enclosure with a DT-3E design, protecting copper windings and electrical connections from dust, moisture, and weather. Plan for proper clearance, secure mounting to the 918AN frame, and compliant conduit routing. Ensure a 208 V to 480 V three-phase supply and use the 255 A winding rating for load sizing.
This transformer provides a 150 kVA rating with copper windings and a fixed primary of 208 V, secondary of 480 V, at 60 Hz. It also includes taps at +5% and -5% to compensate supply variations, enabling consistent voltage to critical loads such as motors and control panels with minimal regulation.
Yes. It carries UL Listed certification and uses a NEMA 3R enclosure, making it suitable for both indoor and outdoor installations. The DT-3E design further supports rugged, code-compliant performance in demanding environments commonly found in manufacturing, processing, and distribution facilities.
The unit provides a tap change option with 1 tap at +5% FCAN and 2 taps at -5% FCBN, enabling voltage adjustments to maintain stable secondary voltage. This helps protect sensitive equipment and reduces nuisance tripping in environments with variable incoming voltage.
The transformer includes Eaton’s warranty of one year from installation or eighteen months from shipment, whichever occurs first. For maintenance, schedule periodic insulation and connection inspections, verify tap settings after service, and monitor for signs of overheating or moisture ingress to sustain performance.
