Eaton Specification Sheet - N29R28T33EE
N29R28T33EE uses a K-Factor nonlinear ventilated design to better manage harmonic heating and hot spots, reducing thermal stress and cooling energy. This translates to improved reliability and longer insulation life in continuous operation plants. It’s well-suited for medium-to high-density power distribution in manufacturing facilities, data centers, and process industries where clean power and uptime matter. The unit delivers a robust 300 kVA three-phase rating with a 208 V primary and 208Y/120 V secondary, supporting standard control panels and motor drives; it includes taps at +5% and -5% to accommodate line drops and voltage variances without swapping transformers. With a 60 Hz operating frequency, integration into North American systems is straightforward, minimizing commissioning risk. Aluminum coil construction combined with a rugged 919 frame supports outdoor or indoor installations while maintaining mechanical integrity over decades of service. The WS35 Weathershield protects equipment in challenging environments, reducing enclosure costs and simplifying site planning. UL Listed, NEMA TP-1 Compliant, and NEMA TP-1 efficient ratings reinforce regulatory alignment and energy-conscious operation, while the electrostatic shield helps suppress EMI in control environments. The one-year warranty (or eighteen months from shipment) reflects Eaton’s commitment to uptime and total cost of ownership, complemented by detailed datasheets and catalog notes for fast, accurate project scoping.
