FAQs
Install the Eaton N29M28T75CUEE in a secure, access-controlled enclosure with proper clearance for ventilation. Connect the 208 V primary to the incoming distribution bus and wire the 208Y/120 V secondary to the load side per NEC guidelines. Use the +2.5% and -2.5% taps as needed to maintain voltage within tolerance, and ensure proper grounding and shielding for EMI control.
The K-Factor nonlinear design reduces adverse effects from harmonic currents, improves heat dissipation, and lowers thermal aging. This translates to higher reliability for drives and controllers, longer transformer life, and reduced maintenance, especially in facilities with nonlinear loads like VFDs and switching equipment.
Yes. With 75 kVA capacity, three-phase operation, copper windings, and a robust 150 °C rise rating, the transformer supports critical loads in data centers and manufacturing lines. Its voltage regulation options and shielding features also contribute to stable power delivery and equipment protection in space-constrained environments.
This transformer is UL Listed and NEMA TP-1 compliant, with NEMA TP-1 efficient catalog notes. These certifications validate safety, efficiency, and electrical performance for industrial installations, helping you meet regulatory requirements and pass audits with minimal risk.
The combination of copper windings, high reliability, and efficient operation reduces energy losses and maintenance intervals. The ability to regulate voltage with taps, along with rugged weather protection and shielding, minimizes downtime, lowers replacement costs, and shortens project timelines, delivering a favorable return on investment over the asset lifecycle.
