Eaton N38D31F75CUEE Transformer - NEMA TP-1 Efficient

K-Factor nonlinear ventilated design improves heat dissipation under nonlinear loading, boosting reliability. This reduces thermal derating and extends service life in facilities with harmonic-rich equipment, such as drives or rectifier-based systems. Ideal for data centers and industrial automation lines where uptime matters. The 75 kVA rating with a 380 V primary and 220Y/127 V secondary delivers sufficient reserve for mid-size equipment, enabling tighter electrical planning and less spare-transformer inventory. Tap-changing capability provides 2 taps at +2.5% and 2 taps at -2.5%, enabling precise voltage regulation to maintain downstream tolerance and reduce equipment stress in fluctuating supply conditions. This is particularly beneficial for critical automated lines and control panels in plant environments. Copper windings and a 115°C rise rating support high continuous loading, improving efficiency and longevity while maintaining thermal margins under peak demand. The transformer’s compliance with UL Listed and NEMA TP-1 efficient standards, along with electrostatic shielding, WS19 weather shield, and a robust build, offer reliable operation in both indoor and outdoor installations, minimizing lifecycle costs. The 916A frame and substantial weight (859 lb) ensure rigidity and vibration resistance in harsh environments, while the WS19 shield enhances EMI resilience for sensitive control electronics. A one-year Eaton warranty provides added peace of mind during initial commissioning and beyond, reducing risk for OEMs and end users.
