Eaton Specification Sheet - N29R28T49EE
The 150 kVA three-phase, 60 Hz design handles peak loads with margin, delivering stable power to automation panels and production lines. This reduces nuisance trips and improves equipment uptime, while enabling design engineers to plan for future capacity in expanding facilities. Tap settings provide precise on-site voltage regulation: 1 tap at +5% and 2 taps at -5% ensure load voltage stays within tolerance as feed conditions vary, minimizing lamp flicker and controller errors in critical processes. Aluminum coil construction on a robust 918A frame supports reliable heat dissipation and long service life, simplifying mounting in standard switchgear assemblies and control cabinets. The transformer’s 150°C rise with a 200°C insulation system enables operation in demanding environments, reducing cooling requirements and overall system cooling costs. Electrostatic shielding and WS34 weather protection suppress EMI/RFI and protect windings from contamination, supporting compliance in challenging plant environments. UL Listed and NEMA TP-1 compliant with NEMA TP-1 efficient notes give procurement teams confidence in safety and efficiency, while the one-year warranty offers peace of mind during initial installation and commissioning. Heavyweight construction is designed for durable, serviceable installations in both indoor equipment rooms and outdoor-rated enclosures, ensuring a long-term supply of stable power for critical processes.

FAQs
Yes. The N29R28T49EE is specified with a 208 V primary and 208Y/120 V secondary, designed for three-phase 60 Hz operation, and fits standard panel and switchgear configurations commonly used in industrial automation and machine control. Ensure mounting clearance and torque specs match the 918A frame to maintain ventilation and service access.
It delivers 150 kVA with taps at +5% and -5% to accommodate supply variation, 60 Hz operation, and an aluminum coil. The 150 °C rise with 200 °C insulation supports sustained loading, while NEMA TP-1 efficiency notes and UL Listed certification provide regulatory confidence in performance and energy use.
Absolutely. The 208 V to 208Y/120 V output is ideal for powering PLCs, drives, and sensors in automation panels. Its electrostatic shielding reduces EMI, and the WS34 weather shield option supports both indoor and outdoor installations in demanding environments, improving uptime and reliability.
This unit is UL Listed and NEMA TP-1 compliant, with NEMA TP-1 efficient notes. These certifications support compliance with safety and energy efficiency standards, aiding audits and helping qualify for utility and project incentives.
Weight is substantial at approximately 1602 lb, so plan for proper rigging and mounting. Aluminum windings and solid frame construction reduce maintenance needs, while the built-in taps simplify on-site voltage adjustment. A one-year warranty from installation provides initial risk mitigation during commissioning and early operation.
