Eaton Specification Sheet - N29R28T12CUEE
The K-Factor nonlinear ventilated design helps manage harmonic currents, reducing voltage distortion and winding heat, which extends asset life and lowers maintenance costs in facilities with high non-linear loads like motor drives and power supplies. This transformer’s rugged construction supports reliable operation in hot shop floors, improving uptime for critical processes. The 112.5 kVA rating paired with 208 V primary and 208Y/120 V secondary matches typical facility power architecture, simplifying panel design and reducing losses in control circuits. Tap options include one +5% tap and two -5% taps, enabling voltage compensation across feeders to protect sensitive equipment and stabilize output under line fluctuations. Copper windings on a 916A frame deliver low resistance, high thermal capacity, and robust mechanical stiffness for long service life in demanding environments. The WS19 weather shield and electrostatic shielding further enhance outdoor and dusty environments, while UL Listed and NEMA TP-1 compliant specifications support regulatory and efficiency targets. This combination supports faster installations, easier maintenance planning, and improved overall system reliability for data centers, manufacturing lines, and OEM builds.

FAQs
For standard panel installations, plan for the 916A frame size and 1107 lb weight, ensuring adequate mounting clearance and crane access. Use copper windings to minimize thermal losses and connect to 208 V service with a 208Y/120 V secondary. Take advantage of the taps: one at +5% and two at -5% to optimize voltage under fluctuating line conditions, and verify a 60 Hz supply.
Key specs include a 112.5 kVA rating, 60 Hz frequency, 208 V primary, 208Y/120 V secondary, and a 150 °C rise with a 200 °C insulation system. The K-Factor nonlinear design mitigates harmonics from drives and power electronics, while copper windings improve efficiency and thermal performance, contributing to reduced overheating and longer service life.
Yes. The transformer’s 112.5 kVA rating and 208/120 V output fit common data center and manufacturing panel applications. UL Listed and NEMA TP-1 compliant, with electrostatic shielding and a WS19 weather shield option, provide regulatory compliance and external protection. Its copper windings and robust 916A frame support continuous operation in demanding environments.
This model is UL Listed and NEMA TP-1 compliant, reflecting compliance with safety and efficiency standards for distribution transformers. It is designed for 60 Hz operation, 208 V primary, and 208Y/120 V secondary, with a 150 °C rise rating and 200 °C insulation system, ensuring predictable performance and regulatory alignment for plant-wide reliability.
Expected ROI comes from improved uptime, reduced harmonic-related losses, and lower maintenance costs due to better thermal management and higher reliability.
