Eaton N48M48T33EE K-Factor nonlinear transformer - KT-13
Part Number: N48M48T33EE
Quick Summary
The Eaton N48M48T33EE K-Factor nonlinear transformer delivers harmonic-aware power conditioning for 3-phase distribution in demanding industrial facilities. In practice, engineers confront harmonics, voltage drop, and overheating under peak loads; this transformer is engineered to reduce those risks while maintaining voltage stability. For compliance, designs in this class are commonly evaluated against CE and UL standards, and many users also request IP ratings or SIL considerations in safety-critical areas; confirm certification with the manufacturer. The unit is a 300 kVA, 480 V primary, 480 delta secondary transformer with KT-13 3-phase configuration and adjustable taps, offering reliable integration into existing low-voltage power networks. This combination helps reduce energy waste and extend motor and switchgear life by maintaining clean, stable power.

FAQs
Plan for proper mounting in a ventilated enclosure or dedicated transformer room, with clearances for cooling and service access. Ensure correct phase connection to the 480 V primary and 480 V delta secondary, and configure taps correctly to achieve the desired voltage regulation. Verify compatible bus configurations and follow manufacturer guidance for wiring, labeling, and protective devices.
The K-Factor nonlinear design targets harmonic currents by closely matching transformer thermal and magnetic response to non-linear loads. This reduces thermal rise in windings, minimizes voltage distortion, and improves overall power quality, which helps protect downstream motors and drives and reduces unwanted trips in high-harmonic environments.
This transformer is designed for robust industrial power distribution, with 3-phase 480 V operation and a 300 kVA rating. For safety-critical uses, verify certifications such as CE or UL and any SIL or IP requirements with Eaton prior to deployment. In critical environments, plan for proper enclosure protection, cooling, and maintenance access to sustain reliability.
The product specifies Certifications as Contact Manufacturer, so confirm with Eaton the exact standards applicable to your region and application. Typical considerations include CE for Europe, UL for North America, and any site-specific requirements for SIL, IP ratings, or environmental certifications. Always obtain official documentation before procurement.
The transformer’s harmonic mitigation and voltage regulation reduce equipment stress, lowering maintenance costs and extending motor and drive life. A 300 kVA rating provides scalable headroom for growth, potentially reducing the need for future transformer upgrades. Expect improved reliability, fewer unplanned outages, and lower energy losses in well-regulated 3-phase systems.
