Eaton MD63E92ZZ Open-core transformer - UL Recognized
Part Number: MD63E92ZZ
Quick Summary
Eaton Open-core MD63E92ZZ Open-core transformer delivers reliable drive isolation for three-phase power distribution in industrial plants. Facilities often fight overheating, insulation wear, and unplanned downtime when ventilation is inadequate in dry-type transformers. UL Recognized certification supports safety compliance and traceability, while the open-core design paired with the DT-3 frame enhances airflow and cooling in demanding service environments. With a 63 kVA rating, 460 V primary and 460Y/266 V secondary, this transformer offers flexible integration for motor control centers, distribution panels, and drive systems. For procurement teams, the aluminum windings and a robust 150 °C rise margin translate to durable performance and lower lifecycle costs.

FAQs
When installing the MD63E92ZZ, ensure adequate ventilation around the open-core assembly to maximize cooling. Provide proper clearance for service access, mount on a rigid frame, and follow UL Recognized safety guidelines. Check that the DT-3 designation and 914S frame fit your enclosure and panel spacing. Plan for the +5% and -5% tap adjustments to accommodate minor supply fluctuations.
Key specs include a 63 kVA rating, 60 Hz, three-phase configuration, 460 V primary, and 460Y/266 V secondary. Taps at +5% FCAN and -5% FCBN allow on-site voltage compensation to maintain output within tolerance during input variation, reducing the need for additional regulation equipment and improving system reliability.
Yes. The MD63E92ZZ is designed as a drive isolation transformer with a dry-type, open-core configuration. Its DT-3 design provides effective isolation between primary and secondary windings, mitigating transients and protecting sensitive drives in motor control centers and power distribution panels.
This unit carries UL Recognized certification, which supports safety compliance and approval processes in many regions. Open-core and coil assembly is noted in catalog information, aiding audits and supplier qualification. Always verify local compliance requirements for your installation and file the UL Recognized mark accordingly.
Maintenance is typical for dry-type transformers: periodic visual inspections, thermal checks, and insulation verification. The aluminum windings and robust 150 °C rise rating contribute to durable operation under higher ambient temps, reducing unplanned downtime. The 63 kVA rating and flexible taps support scalable loads, improving overall ROI through asset longevity and minimized spare-part diversification.
