Eaton Specification Sheet - N48M28T45CUEESRLS42
Feature → Business Impact → Application: K-Factor nonlinear ventilated design reduces harmonic currents and hot spots, improving power quality and reliability in drives, PLCs, and mixed loads. This translates to fewer nuisance trips and longer equipment life in machine control panels and manufacturing lines. Feature → Application: Copper windings deliver lower resistive losses and robust thermal performance, enabling higher efficiency and sustained output in hot environments like panel rooms and switchgear housings. Feature → Application: Precise taps (+2.5%, -2.5%) enable voltage regulation to compensate for input fluctuations, reducing flicker and improving PLC sensor accuracy in critical automation applications. Feature → Application: NEMA TP-1 compliance and UL listing provide regulatory confidence, simplifying audits and reducing installation risk across industrial facilities. Feature → Application: Low 42 dB sound, weather shield WS39, and a compact footprint support quiet operation and outdoor or semi-exposed installations without requiring elaborate enclosures. Feature → Application: 150 °C rise with 200 °C insulation system allows reliable operation in high-ambient facilities and hot production floors, minimizing derating and downtime. Feature → Application: A solid 914D frame and 590 lb weight inform mounting considerations, service access, and secure installation in rugged environments, ensuring long-term durability and easier maintenance. Feature → Application: A one-year warranty (or 18 months from shipment) offers predictable support and total cost-of-ownership advantages for procurement teams evaluating lifecycle costs.

FAQs
For optimal installation, plan space for the 22 in length, 29 in width, and 39 in height footprint and ensure adequate ventilation. Mount the unit on a sturdy surface, align with infeed and load wiring, and leave clear access for maintenance. Use proper wire sizing for 480 V primary and 208Y/120 V secondary circuits and follow local code requirements for grounding and enclosure integrity.
The K-Factor nonlinear ventilated design mitigates harmonic currents and reduces temperature rise under non-linear loads common in drives and controllers. This translates to cleaner power delivery, lower thermal stress, and longer component life in industrial controls, data centers, and automation panels where harmonic content is a concern.
The N48M28T45CUEESRLS42 is NEMA TP-1 compliant and UL Listed, with a documented 42 dB sound level. These certifications simplify regulatory compliance, support safe operation in industrial environments, and aid in passing audits or customer specifications for powered equipment used in manufacturing, facilities management, and process automation.
The taps provide voltage regulation to compensate for supply fluctuations. With two taps at +2.5% and four taps at -2.5%, you can fine-tune the secondary voltage to maintain stable output for sensitive equipment, reducing voltage-related faults and improving PLC accuracy and motor performance in variable input conditions.
Maintenance focuses on periodic inspection of cooling paths, enclosure integrity, and connection torque to prevent overheating. While dry-type ventilation reduces oil-related maintenance, routine checks of windings, terminals, and weather shield components are advised. The 45 kVA rating, copper windings, and robust insulation enable longer service life and lower downtime, contributing to a favorable ROI through improved uptime and energy efficiency.
