Eaton Specification Sheet - N48D28T5516Q
500 kVA K-Factor nonlinear ventilated transformer offers robust handling of harmonic-rich loads while stabilizing voltage. This improves equipment reliability and extends transformer life in demanding processes. Ideal for general-purpose distribution in manufacturing facilities, process plants, and data centers that require consistent power quality. DOE 2016 efficiency compliance reduces energy consumption and operating costs over the life of the asset. UL Listed certification ensures safety and reliability in industrial environments. NEMA 1 enclosure, floor mounting, and GP frame (GPF) simplify installation and protect the asset in indoor spaces while providing accessible service. Aluminum windings reduce weight and improve heat dissipation, aided by insulation rated to 220 °C for dependable performance in elevated temperatures. Tap settings of +2 at 2.5% FCAN and -2 at 2.5% FCBN enable precise voltage regulation to match load changes. The three-phase, 60 Hz design supports seamless integration with standard power distribution networks and downstream equipment.

FAQs
Mounting on a solid floor with a NEMA 1 indoor enclosure and a floor-mount GP frame (GPF) facilitates safe, accessible service. Ensure clearance for front and side panels, adequate ventilation, and access for routine maintenance. Verify mounting location complies with local codes and that load-bearing surfaces can support the transformer’s dimensions and the potential vibration during operation.
This model is a three-phase transformer with a primary voltage of 480 V and a secondary voltage of 208Y/120 V. It is designed for 60 Hz operation and includes aluminum windings. The dual-secondary configuration supports common 208Y/120 distributions in mixed industrial/facility environments, enabling straightforward connection to downstream equipment and panels.
Yes. The transformer meets DOE 2016 efficiency targets, providing improved energy performance over traditional designs. It is UL Listed, confirming compliance with rigorous safety and reliability standards for industrial equipment, which helps with procurement approvals and regulatory audits while reducing risk in critical power systems.
The unit features taps at +2 at 2.5% FCAN and -2 at 2.5% FCBN, allowing ±2% regulation around the nominal secondary voltage to counteract voltage drop or elevation under load. Adjust taps during commissioning or after significant network changes, then monitor downstream voltage to maintain within the desired tolerance throughout operation.
The K-Factor nonlinear ventilated design reduces harmonic impact, improving power quality and reducing stress on downstream equipment. DOE 2016 efficiency lowers operating costs, while UL Listing and NEMA 1 enclosure simplify safety compliance. Over time, the combination of lower energy use, reduced cooling needs, and longer asset life translates to lower total cost of ownership and higher uptime.
