FAQs
For installation, plan floor mounting in a clean, dry indoor space with adequate clearance for service access. The unit measures 24.88 in wide, 36.88 in high, and 21.13 in deep, weighing 422 lb. Provide 480 V delta input and 208Y/120 V four-wire output, with 60 Hz operation and a 0° phase shift. Ensure venting/clearance per local codes and maintain access to taps (+2.5% and -2.5%).
The X48M28T4516CUNONLS45 is designed as a DOE 2016 efficient dry-type transformer, and is UL Listed in compliance with 10 CFR Part 431. These certifications confirm energy performance targets, reduced stray losses, and overall lower operating costs, making it suitable for energy-conscious facilities and regulatory programs.
Yes. With a 45 kVA rating, three-phase 60 Hz operation, 480 V delta primary, and 208Y/120 V secondary, it supports high-quality power delivery to critical equipment. The 0° phase shift helps maintain power factor, while 45 dB sound level and NEMA 2 enclosure are appropriate for controlled environments like data halls and production floors.
The transformer is backed by Eaton’s standard policy: one year from installation or eighteen months from shipment, whichever occurs first. The UL Listing and DOE 2016 compliance provide regulatory assurance, and Eaton offers ongoing technical support and parts availability to minimize downtime during maintenance or upgrades.
Key specs include 45 kVA, three-phase, 60 Hz, primary 480 V delta, secondary 208Y/120 V four-wire, and 0° phase shift. Tap options include 2 taps at +2.5% and 4 taps at -2.5% to support voltage balancing under variable load. Copper windings, 220 °C insulation, and 150 °C rise contribute to robustness in demanding environments.
