Eaton N48M28F12CUEESR Nonlinear Ventilated Transformer - NEMA TP-1 Efficient
Part Number: N48M28F12CUEESR
Quick Summary
The Eaton N48M28F12CUEESR nonlinear ventilated transformer delivers reliable three-phase power conditioning for industrial distribution systems. Engineers and procurement teams often struggle with harmonic distortion, voltage swings, and high heat that shorten equipment life and complicate regulatory compliance. This design emphasizes NEMA TP-1 efficiency, an electrostatic shield, and WeatherShield WS19, providing quieter operation, EMI control, and outdoor resilience in rugged facilities. Designed for 480 V primary and 208Y/120 V secondary loads, with copper windings and selectable taps, it supports voltage regulation and continuity across fluctuating plant conditions. Together, these features enable easier panel integration, reduced energy waste, and lower total cost of ownership for manufacturers and critical-process environments.

FAQs
Installation for the N48M28F12CUEESR should begin with confirming the 283B wiring connection and the 916A frame compatibility for your panel enclosure. Mounting should allow adequate ventilation to support the 115°C rise rating, and space must be provided for heat dissipation and access during maintenance. Plan for three-phase 60 Hz operation with a 480 V primary and 208Y/120 V secondary to ensure safe terminations and compliance.
Key performance specs include a 112.5 kVA rating, 60 Hz frequency, and three-phase configuration, with a 480 V primary and 208Y/120 V secondary. Tap options are +2.5% and -2.5%, supporting voltage regulation for fluctuating supply, while copper windings deliver low resistance losses. The transformer operates with a 115 °C rise and comes in frame 916A with copper windings and 283B wiring.
Yes, the N48M28F12CUEESR is designed for rugged environments using electrostatic shielding to reduce EMI and WeatherShield WS19 for environmental protection. Outdoor viability is enhanced when mounted with appropriate enclosures and ventilation. The unit also aligns with energy and noise standards through NEMA TP-1 efficiency and a certified sound level report, supporting compliant outdoor installations in industrial settings.
The transformer features taps at +2.5% and -2.5% to adjust secondary voltage in response to feeder drops or supply swings. This enables tighter voltage regulation for sensitive drives, PLCs, and control panels, reducing under- or over-voltage events that can degrade performance, shorten component life, or cause nuisance trips in critical processes.
