Feature: The K13 K-Factor nonlinear design is engineered to tolerate harmonic currents without excessive heating. Business impact: This reduces cooling energy, lowers total cost of ownership, and extends transformer life in mission-critical applications. Application: Ideal for data centers, machine controls, and switchgear enclosures in harsh industrial environments. The result is improved reliability under varying load and harmonic profiles. Feature: Vented XFMR construction supports designed-in natural convection for effective cooling. Business impact: Lower operating temperatures translate to higher efficiency, reduced maintenance windows, and longer service intervals. Application: Suits installations with limited fan-assisted cooling, in compact electrical rooms and switchgear vaults. This design also improves resilience in environments with dust, moisture, or intermittent airflow. Feature: The 75 kVA three-phase rating with a 480-208Y/120 V output streamlines power distribution for critical loads. Business impact: Fewer transformers in the feed path reduce capital expense, improve redundancy, and simplify maintenance. Application: Suitable for motor drives, control panels, manufacturing lines, and data center equipment racks. Compatibility: Inputs align with common 480 V utility services and 208Y/120 V secondary distributions, helping you avoid adapters. Feature: UL Listed safety certification underscores compliance with recognized electrical safety standards. Business impact: Procurement teams gain confidence to qualify the transformer for regulated environments and OEM approval processes. Application: Widely applicable in utilities, manufacturing plants, and automation installations requiring formal safety documentation. Additionally, Eaton provides datasheets and multimedia resources to support installation, inspection, and long-term reliability. Feature: Documented dimensions and weight facilitate planning and integration. Business impact: Clear footprint data simplifies site planning, mounting, and compliance with enclosure clearances. Application: Fits standard electrical rooms, switchgear cabinets, and retrofit projects where footprint and weight matter. Notes on compatibility and installation are available in Eaton's specification sheet and the accompanying video guide.

FAQs
When planning installation, verify the transformer footprint (21.13 in L × 24.88 in W × 36.88 in H) and weight (430 lb) to confirm rack or pad mounting. Ensure adequate ventilation for the vented XFMR, provide proper clearance around the enclosure, and connect to a dedicated 480 V supply with a 208Y/120 V secondary distribution as specified. Use appropriate lugs and terminals; consult Eaton's specification sheet for terminal torque and wiring diagrams.
The K13 nonlinear design is engineered to tolerate harmonic currents without excessive heating, reducing dielectric stress and thermal buildup. This yields improved efficiency, lower cooling requirements, and longer transformer life under non-linear loads common in drives and power supplies. Data centers and automation panels particularly benefit from stable voltage regulation and reduced overheating risk.
Yes. With 75 kVA three-phase capacity and 480-208Y/120 V output, it supports critical IT equipment, motor drives, and control panels. The vented design assists with heat dissipation, while UL Listed certification supports safety compliance for data halls and manufacturing floors. Consider matching with switchgear and UPS systems to optimize redundancy and reduce space requirements.
The N48M28T7521I4 is UL Listed, confirming compliance with recognized electrical safety standards for industrial equipment.
