Eaton NT20P11B15CUEE Transformer - 15 kVA, 80°C rise
Part Number: NT20P11B15CUEE
Quick Summary
Eaton K-Factor nonlinear ventilated transformer is designed to condition and stabilize power in industrial control panels and distribution systems. Engineers often confront voltage fluctuations, heat buildup, and mis-sized taps that undermine reliability. This single‑phase unit delivers an 80°C rise and KT‑13 characteristics with taps at +5%, -5%, +2.5%, and -2.5% to adapt to site conditions, while copper windings enhance efficiency. Certifications vary by region and configuration, so confirm status with the manufacturer; CE and other approvals are commonly pursued where applicable. For buyers, the combination of robust regulation, compact footprint, and flexible voltage options translates into reduced downtime, improved panel performance, and lower life-cycle costs for power management and distribution applications.
