K-Factor nonlinear ventilated design reduces harmonic distortion and minimizes winding heating, delivering improved reliability under heavy load and varying power quality in manufacturing floors and processing lines. The business impact is lower maintenance needs and reduced downtime, enabling steadier output in critical processes. This makes it ideal for three-phase distribution in environments with reactive or harmonic-rich loads. Aluminum windings offer corrosion resistance and a lower material cost compared with copper, translating to cost-effective installations and easier procurement, especially for larger facilities where long-term energy costs matter. The DOE 2016 Efficient compliance and UL Listed certification provide regulatory assurance and energy savings, supporting corporate sustainability goals and easier audits. A NEMA 2 enclosure supports indoor installations with robust protection against dust and moisture, while floor mounting simplifies site integration and minimizes retrofit complexity in existing plants. With a 150 kVA rating, 208 V primary and 480 V secondary, the unit supports scalable power distribution and motor loads across multiple lines, reducing the need for multiple transformers. The electrostatic shield modification enhances short-circuit withstand and EMI control, improving protection for sensitive equipment and control systems. The WS61 Weathershield option expands installation flexibility in semi-indoor spaces, and EB29R23 wiring connections align with Eaton’s standard interfaces, reducing commissioning time and installation errors. The substantial footprint and 1490 lb weight are offset by a robust, serviceable design that supports routine maintenance and long service life, delivering a predictable total cost of ownership for industrial automation projects.

FAQs
This transformer weighs 1490 lb and is designed for floor mounting with a footprint of approximately 33.5 in by 38 in and a height of 60 in. Ensure the supporting floor structure can bear the weight, provide adequate clearance for ventilation and service access, and connect per the EB29R23 wiring standard. Allow space for maintenance and inspection, and plan for routing of power and control wiring to minimize heat buildup and EMI exposure.
The K-Factor nonlinear design mitigates harmonic currents, reducing winding overheating and improving overall efficiency under non-linear load conditions. This translates to lower thermal stress and longer component life in facilities with variable motor startup and harmonic-rich equipment. It is well suited for automation lines, power-intensive machines, and facilities with mixed loads where power quality is critical.
Yes. The N29R48T4916 is a three-phase transformer with a 208 V primary and 480 V secondary, rated at 150 kVA, operating at 60 Hz. This configuration supports common industrial distribution schemes and motor drives, enabling efficient power transfer with a compact footprint compared to multiple smaller transformers.
The unit is UL Listed and adheres to DOE 2016 Efficient standards, with 10 CFR Part 431 compliance noted in catalog documentation. These certifications support regulatory compliance, energy efficiency goals, and performance reliability across regulated industrial applications.
Energy efficiency from DOE 2016 compliance reduces energy losses during operation, while the robust aluminum winding and NEMA 2 enclosure offer durable service in indoor environments. The reduced risk of overheating and longer service life lower maintenance cycles and downtime, delivering a favorable total cost of ownership for facilities with high uptime requirements and long-term power distribution needs.
