Eaton Specification Sheet - N38M28F45CSCUEELS42
Feature: The K-Factor nonlinear ventilated design accommodates harmonic-rich non-linear loads, maintaining voltage stability and reducing peak current stresses on transformers. Business Impact: Lower heat rise and improved insulation life translate to reduced maintenance cycles and lower lifecycle costs for mission-critical loads. Application: This configuration is well suited to motor drives, inverters, and automation cabinets in process industries where harmonic currents challenge conventional transformers. Feature: The 3-phase KT-13 arrangement with a 380 V primary and 208Y/120 V secondary supports broad compatibility with existing plant power rails. Business Impact: Simplified wiring, fewer conversion stages, and consistent secondary voltage improve panel reliability and reduce commissioning time. Application: Particularly beneficial in machine tools, packaging lines, and assembly cells where reliable 208Y/120 V control power is essential. Feature: Field-adjustable taps at +2.5% and -2.5% provide fine voltage regulation to compensate for supply fluctuations. Business Impact: Precise voltage control minimizes nuisance tripping, protects sensitive electronics, and optimizes downstream PLCs and drives. Application: Ideal for long feeders, remote panels, and retrofit projects where mains tolerance must be tightly managed. Feature: Copper windings deliver low resistance, high efficiency, and robust thermal performance under non-linear loading. Business Impact: Reduced I2R losses and improved heat dissipation lower operating costs and extend service life in harsh factory environments. Application: Suited for control cabinets, packaging equipment, and automation cells where consistent efficiency matters for reliability. Feature: Ventilated construction with elevated radiant heat handling supports compact installations. Business Impact: Higher density power distribution reduces footprint and allows safer, more accessible maintenance in restricted spaces. Application: Works well in Eaton-based power distribution schemes and modular electrical rooms across manufacturing plants.

FAQs
Plan for adequate ventilation to maximize the transformer’s vented cooling capability and ensure clearances around the unit for heat dissipation. Verify panel space to accommodate the 45 kVA class while providing easy access for tap adjustments (+2.5%/−2.5%). Check that input and output wiring matches the 380 V primary and 208Y/120 V secondary configuration and that protective devices are sized for non-linear loads.
The 380 V primary paired with a 208Y/120 V secondary supports standard industrial power rails while delivering a stable low-voltage supply for controls and instrumentation. This arrangement reduces the need for bulky step-down stages, simplifies wiring in control panels, and improves voltage regulation across mixed loads such as drives, sensors, and PLCs, especially in facilities with fluctuating line voltages.
Yes. The transformer employs a K-Factor nonlinear design (KT-13) intended to better tolerate harmonic currents common in power electronics and drives. With copper windings and ventilated cooling, it maintains efficiency and temperature rise under non-linear loading, helping protect connected equipment and reducing the risk of saturation and overheating during peak harmonic events.
Routine maintenance should focus on ensuring proper ventilation, inspecting bushings and connections for signs of overheating, and confirming left-to-right alignment of primary and secondary terminations. Monitor temperature rises during peak loads and verify the integrity of taps at +2.5% / -2.5%. Clean dust from vents and ensure protective enclosures remain intact to preserve cooling efficiency.
ROI considerations include reduced downtime from improved harmonic handling, lower energy losses due to copper windings, and extended transformer life from better heat management. The 45 kVA rating provides scalable capacity for growing load profiles, while the taps enable voltage regulation to minimize tripping and protection device wear, all contributing to lower total cost of ownership in automation and distribution applications.
