Eaton transformer - N48M28F50CUEE KT-13 UL Listed
Part Number: N48M28F50CUEE
Quick Summary
Eaton transformer N48M28F50CUEE delivers high‑reliability K‑Factor nonlinear ventilation for three‑phase power distribution in industrial facilities. In many installations, overheating, voltage transients, and limited panel space slow projects and shorten equipment life. UL Listed certification and a NEMA 2 enclosure provide compliant, rugged protection, while the KT-13 design ensures stable performance under varied loads. With a 50 kVA rating, 480 V primary and 208Y/120 V secondary output, and 60 Hz operation, this transformer supports scalable deployments across manufacturing, data centers, and automation racks. Taps at +2.5% and -2.5% enable precise voltage regulation in fluctuating supply conditions. The result is improved reliability, reduced downtime, and lower lifecycle costs when integrated into existing Eaton power management ecosystems.

FAQs
Plan for safe handling of a 824 lb transformer, including crane or pallet jack access and proper anchoring. Ensure adequate clearance for ventilation and access to taps, terminals, and the Frame 916A mounting area. Verify indoor NEMA 2 enclosure suitability, electrical room space, and compatibility with existing panel hardware and Eaton power management systems.
The N48M28F50CUEE provides a 480 V primary and a 208Y/120 V secondary. It is rated at 50 kVA, 60 Hz, three‑phase. This combination supports moderate to heavy automation loads while maintaining stable voltage regulation and efficient power transfer in industrial facilities.
Tap settings (+2.5% and -2.5%) allow on‑site voltage adjustment to compensate for supply fluctuations and ensure downstream equipment sees the correct voltage. Use +2.5% taps when line voltage tends to run low and -2.5% taps when voltage is high, maintaining PLCs, drives, and controls within tolerance.
Yes, the transformer is UL Listed, confirming compliance with safety and performance standards. It uses a NEMA 2 enclosure, providing protection suitable for indoor electrical rooms and factory environments where dust and moisture exposure is minimal but possible.
The unit carries Eaton’s warranty of one year from installation or eighteen months from shipment, whichever occurs first. For maintenance, rely on copper windings and robust KT‑13 design to minimize insulation stress, with routine thermal checks and cooling paths kept clear to sustain efficiency and extend service life.
