FAQs
Installers should plan for 3‑phase 480 V input and 208Y/120 V secondary outputs, with attention to available ventilation to support the transformer’s 150°C rise rating. The unit uses copper windings and offers ±2.5% taps for voltage regulation; ensure adequate clearance, appropriate enclosure (if required by environment), and compliance with local safety standards.
This transformer employs a K-Factor nonlinear design intended to limit overheating in harmonic-rich environments. The 112.5 kVA rating provides ample headroom for peak loads, reducing the risk of voltage distortion and equipment stress on motors and drives, while copper windings improve efficiency and thermal performance.
Certifications for this model are listed as 'Contact Manufacturer' in the provided data. In practice, CE marking and other safety certifications are commonly pursued by manufacturers for European installations, with IP and SIL considerations typically evaluated per project requirements by Eaton and the installing integrator.
The taps allow ±2.5% voltage adjustment in multiple windings, enabling tighter voltage regulation across varying supply conditions. This reduces voltage fluctuations seen by connected equipment, improving performance and extending the life of motors and control systems in manufacturing lines.
