FAQs
The N48M28B12CUEELS45 is a three-phase transformer rated 112.5 kVA with a 480 V primary and 208Y/120 V secondary, designed for standard industrial power distribution. It supports 60 Hz operation and copper windings, with 2 taps at +2.5% and 4 taps at -2.5% for voltage regulation, ensuring compatibility across common facility feeders and motor drives.
The K-Factor nonlinear design manages nonlinear loads to reduce overheating and improve voltage regulation. This translates to longer transformer life, lower maintenance, and better overall efficiency in facilities with variable harmonic content from drives and power electronics.
Yes. The N48M28B12CUEELS45 is UL Listed and NEMA TP-1 compliant, with electrostatic shielding and an 80°C rise, delivering safer operation and compliance for industrial environments.
Plan for enclosure and room acoustics near the transformer, given the 45 dB sound level, and ensure proper ventilation for the ventilated design. Use the adjustable taps for voltage regulation during commissioning, and verify compatibility with 480 V/208Y/120 V supplies and related switchgear.
Eaton supports a policy where coverage begins one year from installation or 18 months from shipment, whichever occurs first. Always verify current terms with the vendor and document installation dates to maximize coverage.
