FAQs
The transformer supports a 480 V primary and a 480Y/277 V secondary, operating at 60 Hz. With copper windings and a 112.5 kVA rating, it integrates cleanly into standard North American power architectures while providing regulation through taps. Its footprint and frame are sized for mid-size plant feeders, enabling straightforward panel integration and minimal retrofit work.
The K-Factor nonlinear design targets harmonic-rich loads, reducing electrical stress and improving overall efficiency. Copper windings offer superior conductivity, while the 150 °C rise insulation system supports higher operating temperatures. In practice, you gain better voltage stability under peak demand, reduced heat-related losses, and longer service life for critical lineups.
Yes. The N48M47T12CUEE is UL Listed and NEMA TP-1 compliant, with a catalog note indicating NEMA TP-1 efficiency. These certifications ensure safety, reliability, and consistency with electrical codes in industrial facilities. The unit’s Weathershield WS19 and rugged frame further support compliance in varied environments.
Key ROI drivers include the 150 °C rise insulation system and copper windings, which support long-term reliability and lower maintenance frequency. The 112.5 kVA rating matches common plant loads, and the 60 Hz specification ensures compatibility with grid cycles. A warranty of one year from installation or 18 months from shipment helps mitigate early lifecycle risk.
Plan for a footprint of 23.42 in D, 28.22 in W, 48.56 in H, and a weight of 1235 lb, plus 916A framing. The unit’s 2+2 tap configuration requires proper field wiring and voltage regulation planning. With WS19 weather shielding, outdoor or harsh environments are feasible, but crane or rigging support may be needed during installation.
