Ventilated, dry-type DT-3 construction improves cooling and safety in motor-drive installations. The design promotes air circulation around windings, reducing thermal rise during peak VFD operation and extending insulation life. Lower operating temperatures translate into longer maintenance intervals and reduced cooling penalties in crowded MCCs. Use cases include variable-frequency drives, servo systems, and high-inertia motors where heat is a limiting factor. Copper windings provide a robust, low-resistance path from primary to secondary. The 75 kVA rating supports demanding drive loads while preserving voltage regulation across feeders and panels. This combination yields higher system efficiency and reduced transformer losses, which lowers energy costs over the life of the installation. Applications span metalworking, plastics, and packaging lines where dependable isolation is critical. Primary 208 V, secondary 208Y/120 V, with 60 Hz three-phase operation match common industrial power systems. Tap options at +5% FCAN and -5% FCBN enable on-site voltage adjustment to compensate supply variations. The 22 in depth, 29 in width, and 39 in height fit standard control enclosures and MCC sections with ample door clearance. The 915D frame supports straightforward mounting and service access, even in dense installations. WS39 weathershield protects exposed windings in outdoor or harsh indoor environments. The UL Listed certification demonstrates compliance with essential safety standards for industrial equipment. This combination reduces qualification effort during audits and speeds up deployment in regulated sectors such as food & beverage, oil, and chemical processing. Warranty follows Eaton policy 25-000, offering one year from installation or eighteen months from shipment, whichever comes first. The unit's weight of 706 lb and integrated frame enable secure, vibration-resistant mounting in fixed installations and cabinets. For installation teams, the unit's standard dimensions and copper windings facilitate migration from legacy transformers and easier wire terminations. This is complemented by Eaton support resources including installation guides and online datasheets.

FAQs
Plan for adequate space to accommodate a 22 in depth, 39 in height, and 29 in width transformer. The unit weighs 706 lb and uses a 915D frame, so provide appropriate mounting hardware and load-rated supports. Ensure proper ventilation clearance around the WS39 shield and allow space for wire terminations and taps (+5% / -5%).
The transformer is a three-phase, 75 kVA unit with a 208 V primary and a 208Y/120 V secondary, rated for 60 Hz operation. It features copper windings and voltage taps at +5% FCAN and -5% FCBN to accommodate on-site voltage variations. The design is DT-3 dry-type with vented cooling.
Yes. The MD75E83FCU is a dedicated drive isolation transformer with vented dry-type construction (DT-3) and 75 kVA capacity, designed to isolate motor drives from line disturbances. It reduces transients, protects sensitive drives, and supports reliable operation of VFDs, servo drives, and other power electronics within MCCs.
The MD75E83FCU carries UL Listed certification, validating safety compliance for industrial equipment. This helps meet regulatory and contractor requirements during audits and installation qualification. If CE or other regional certifications are needed for a project, confirm with Eaton or local authorities, as the data provided specifies UL Listed only.
