FAQs
Follow the Eaton installation guide for a 480 V three-phase system. Connect primary windings to the 480 V supply and route the 208Y/120 V secondary to the respective distribution circuits. Use the +2.5% and -2.5% taps as needed to regulate voltage under load. Ensure proper ventilation, clearance, and adherence to local codes; verify connections match the KT-13 configuration and consult the datasheet for torque specs and mounting guidelines.
Key specs include 75 kVA rating, 480 V primary, 208Y/120 V secondary, KT-13 three-phase configuration, and a K-Factor nonlinear design. It provides primary voltage regulation through ±2.5% taps and uses a ventilation-assisted cooling system rated for 150°C rise with a 200°C insulation system. These details guide protection settings, wiring schemes, and harmonics management for non-linear loads.
Yes. The K-Factor nonlinear design mitigates harmonic currents from non-linear loads, improving voltage stability and protecting downstream equipment. It is well-suited for data centers, motor drives, and manufacturing lines where harmonic content is high and reliability is critical. Verify site-specific compliance with Eaton for any required certifications.
The product lists Certifications as Contact Manufacturer, so confirm required certifications such as CE, UL, or SIL with Eaton prior to procurement. Review the Eaton datasheet and performance documents for relevant test data, and request any country-specific conformity assessments to ensure regulatory compliance for your installation.
Maintenance is typically routine for power transformers: inspect cooling, verify taps not corroded, and monitor insulation integrity and temperature rise. ROI benefits come from improved voltage regulation, reduced harmonic-related losses, and quieter operation (EE/LS design). Align maintenance intervals with Eaton guidelines and your facility’s preventive maintenance program to maximize uptime and lifecycle value.
