Eaton N38M31T50EE Transformer - UL Listed, TP-1

The K-Factor nonlinear design reduces harmonic distortion and circulating losses, delivering tangible efficiency gains for heavy loads and sensitive electronics alike. This translates to lower cooling requirements and cooler switchgear compartments, which in turn extend equipment life and reduce maintenance cycles in demanding manufacturing environments. The transformer’s tap capability provides targeted voltage regulation, with 2 taps at +2.5% and 4 taps at -2.5%, enabling precise compensation for voltage drop along feeders and long cable runs; the result is improved motor performance and fewer nuisance trips in production lines. UL Listed and NEMA TP-1 compliant status simplifies procurement and regulatory audits, while NEMA TP-1 efficiency notes confirm optimized energy use in power management circuits. Compatibility with standard switchgear and the 914D frame facilitate straightforward installations in existing racks or enclosures, minimizing retrofit time. The aluminum coil construction reduces copper weight and supports efficient heat dissipation, contributing to lower operating temperatures and extended insulation life. With a 50 kVA rating and 380 V to 220Y/127 V outputs, the unit supports a broad spectrum of loads, from drives to lighting to control panels. The transformer’s electrostatically shielded design enhances protection against EMI, and the WS39 weathershield option expands outdoor applicability in exposed environments. A 150 °C rise temperature class paired with a 200 °C insulation system provides a robust safety margin for continuous operation in moderate to harsh ambient conditions. Industry professionals also value the compact physical footprint—22 in depth, 39 in height, and 29 in width—alongside a manageable weight of 554 lb, which simplifies crane-lift planning and site readiness. Finally, Eaton’s 25-000 warranty policy offers a clear service expectation, supporting uptime and long-term budget planning for power distribution projects.
