Eaton N29M28T75CU Transformer - K-Factor nonlinear

The K-Factor nonlinear ventilated design reduces harmonic distortion and improves load stability, delivering cleaner power to drives, controls, and sensitive sensors. This translates to fewer coolant or cooling system trips and longer equipment life, especially in variable loading scenarios found in motor control centers and process lines. In practice, you’ll see more consistent voltage during peak demands and less require corrective actions in the PLC and VFDs. With a 75 kVA three-phase rating and copper windings, the transformer delivers robust real power handling while minimizing copper losses and heat generation. The copper windings contribute to higher efficiency under typical loads and improved thermal performance during peak demand. This is beneficial for energy budgets and reduces cooling loads in plant rooms. Voltage regulation is supported by ± taps (+2.5% and -2.5%), enabling field balancing to maintain the secondary at the desired level as input conditions drift. This feature simplifies commissioning and reduces system downtime during load shifts. It also helps meet device tolerances in sensitive equipment like servers, drives, and instrumentation. Electrostatic shielding reduces capacitive coupling and EMI/RFI into adjacent equipment, helping to meet installation-specific regulatory requirements. The WS39 weather shield option enhances outdoor or harsh-environment resilience, enabling outdoor siting or rooftop installations without compromising performance. Together, shielding and ventilation contribute to lower enclosure maintenance over the system lifetime. Physical footprint and mounting considerations are straightforward: 22 inches long, 29 inches wide, 39 inches high on a 915D frame with a 922 pound weight. The weight and frame standardization simplify crane-lift planning and palletized deliveries, reducing installation risk. The combination of size, build quality, and reputable manufacturer support supports faster ROI through predictable maintenance intervals and service parts availability. From design to commissioning, you gain industry-aligned reliability with copper-wound, ventilated construction designed for 60 Hz operation and 208 V systems. This helps engineers meet power quality objectives, comply with internal standards, and reduce the total cost of ownership across equipment fleets.
