Feature → Business Impact → Application The MD34E97NV uses a totally enclosed non-ventilated DT-3 dry-type design, reducing dust ingress and simplifying maintenance in harsh industrial spaces, which translates to longer service intervals and lower lifecycle costs; Application: panels and MCCs in manufacturing lines. Feature → Business Impact → Application It provides a 34 kVA rating with 575 V primary and 480 V secondary in a three-phase, 60 Hz system, enabling efficient power distribution from higher fault-tolerant feeds to downstream equipment; Application: drives and control systems requiring stable 480 V output. Feature → Business Impact → Application Tap changes at +5% and -5% allow in-situ voltage regulation, improving performance of sensitive loads and reducing nuisance tripping during supply fluctuations; Application: equipment sensitive to voltage variance in mixed-spec environments. Feature → Business Impact → Application Aluminum windings and a rugged 914DN frame offer corrosion resistance and structural integrity for long-term reliability in outdoor or dusty facilities; Application: large electrical rooms and enclosure spaces with limited ventilation. Feature → Business Impact → Application UL Listed certification and Eaton’s warranty policy provide safety assurance and predictable service, minimizing regulatory risk and enabling faster procurement; Application: equipment upgrades and new builds with strict compliance requirements.

FAQs
The MD34E97NV is designed as a 914DN frame, with dimensions 22 in (depth) Ă— 39.18 in (height) Ă— 29 in (width) and a weight of 542 lb. Ensure adequate clearance for service access and ventilation per local codes; although it is a totally enclosed non-ventilated transformer, allow space for cable terminations and mounting hardware. Use appropriate mounting rails or bolt patterns and ensure the cabinet supports at least the unit weight plus installation hardware.
The transformer is three-phase with a 575 V primary (delta) and 480 V secondary, operating at 60 Hz. It provides a 34 kVA rating and includes taps at +5% FCAN and -5% FCBN for voltage regulation under load, suitable for drive isolation and control panel distributions in industrial settings.
Yes. Designed as a drive isolation transformer (DT-3), it helps decouple motor drives from supply fluctuations, reducing transients and improving drive performance. The aluminum windings and rugged enclosure support reliable operation in demanding environments common to motor control centers.
The MD34E97NV carries UL Listed certification, indicating recognized safety compliance for electrical equipment. When deploying in global facilities, verify regional requirements such as CE marking or IP ratings applicable to the installation site; consult the official Eaton datasheets for any region-specific certifications.
Eaton provides a one-year warranty from installation or eighteen months from shipment, whichever occurs first (policy 25-000). This, combined with UL Listed safety certification, supports risk mitigation during commissioning and ongoing operation.
