FAQs
Plan for a robust mounting footprint: dimensions are 23.42 in L, 28.22 in W, 48.56 in H with a weight around 920 lb. Use the base for easy leveling and secure attachment in exposed or enclosed environments. Ensure adequate clearance for ventilation and access to taps (+2.5% / -2.5%).
Key specs include 112.5 kVA rating, 480 V primary, 208Y/120 V secondary, and 60 Hz operation. The taps allow +2.5% and -2.5% adjustments to mitigate feed fluctuations, preserving output voltage at critical equipment and reducing downtime from voltage excursions.
Yes. The transformer’s nonlinear K-Factor design handles harmonic loads, while UL Listed and NEMA TP-1 compliance support regulatory requirements. Electrostatic shielding and WS19 weather shielding add protection for reliability in demanding manufacturing environments and data-center adjacencies.
Verify UL Listed status and NEMA TP-1 efficiency compliance. Protective features include electrostatic shielding and the WS19 weather shield option. Materials like aluminum windings and a 150 °C rise rating provide robust performance under demanding loads and elevated temperatures.
Warranty follows Eaton’s policy: 1 year from installation or 18 months from shipment, whichever occurs first. Routine maintenance focuses on thermal management, ensuring ventilation stays unobstructed, and periodic inspection of taps and enclosure seals. This minimizes unexpected downtime while preserving transformer efficiency and compliance over time.
