Eaton MD175E73NV Transformer - UL Listed, DT-3
Part Number: MD175E73NV
Quick Summary
The Eaton MD175E73NV transformer serves as a drive isolation solution for three-phase power distribution in demanding industrial environments. It provides robust isolation and reliable power delivery for motor drives, control panels, and harsh production floors. Engineers often struggle with enclosure reliability, heat management, and installation compatibility in space-constrained machines; this unit is designed to address those challenges with a compact footprint and a totally enclosed non-ventilated construction. UL Listed certification adds confidence for compliance and safety in regulated facilities. The DT-3 dry-type design, 150 °C rise rating, and aluminum windings deliver long-term performance with reduced maintenance. Secondary benefits include standard taps for voltage flexibility and a 175 kVA rating suitable for decentralised or centralised power applications.
