FAQs
To install this transformer, verify the 480 V primary supply and 400Y/231 V secondary loads, ensure proper enclosure and clearance, and select the appropriate wiring connection (201X). Outdoor use benefits from Weathershield WS35, and indoor installs should follow UL and NEMA TP-1 guidelines. Prepare for the 350 kVA rating by confirming pad or rack mounting space and cooling requirements, while respecting the center coil indicators for ongoing status checks.
The unit uses copper windings with a design tuned for harmonic mitigation and a 0° phase shift in a three-phase system, improving voltage stability and reducing distortion. Dual taps at +2.5% and -2.5% help compensate for line fluctuations, keeping downstream equipment within tolerance. UL Listed and NEMA TP-1 efficiency further ensure compliance and reliable performance in demanding environments.
Yes. The transformer is UL Listed and designed to meet NEMA TP-1 efficiency standards, aligning with industry safety and energy-performance requirements. Additionally, it includes two center-coil thermal indicators that support proactive maintenance and compliance with standard operating procedures.
The two embedded thermal indicators in the center coil provide at-a-glance status on operating temperature and load resilience. This enables preventive maintenance teams to identify overheating risks before they become failures, reducing unplanned outages and extending transformer life in demanding production environments.
Warranty details follow Eaton’s policy 25-000: one year from installation or eighteen months from shipment, whichever occurs first. This is complemented by UL/TP-1 compliance and the unit’s rugged dry-type construction, which supports predictable maintenance needs, reduced total cost of ownership, and improved ROI for long-term power reliability.
