FAQs
This transformer is designed for a 480V delta primary and 208Y/120V secondary, rated at 300 kVA. It uses factory taps (+5% FCAN, -5% FCBN) to simplify voltage regulation during commissioning. Ensure proper enclosure placement (NEMA 3R) and follow UL-listed installation standards for safe, code-compliant operation.
K-Factor nonlinear design indicates the transformer manages harmonic content more effectively, reducing winding heating and stray losses when non-linear loads are present. This translates to better thermal performance, longer insulation life, and improved efficiency under real-world multi-load conditions.
Yes. With a 300 kVA three-phase rating, 480V delta primary, 208Y/120V secondary, copper windings, and DOE 2016 efficiency, the N29R28T1216CU-US is well-suited for data centers, manufacturing lines, and HVAC power distribution, delivering reliable power with regulated output and fast commissioning.
The unit is UL Listed and DOE 2016 compliant, with 60 Hz operation and a NEMA 3R enclosure. It also notes 10 CFR Part 431-2016 compliance in the catalog notes, supporting regulatory alignment and safety in industrial environments.
Expect energy savings from DOE 2016 efficiency, reduced heat load thanks to K-Factor nonlinear design, and durable insulation rated to 220 °C with a 150 °C rise. Regular inspections of taps, enclosure integrity, and winding condition help maximize uptime and extend transformer life, improving total cost of ownership.
