FAQs
MD63E96 is designed around a 914D frame with a 22 in length, 39 in height, and 29 in width footprint. It uses a 286H wiring connection and offers taps at +5% FCAN and -5% FCBN for voltage regulation. It supports three-phase 575 V primary and 575Y/332 V secondary at 60 Hz, suitable for mounting in control rooms, cabinets, or on-floor enclosures near drives.
Core metrics include a 63 kVA rating, 575 V primary, 575Y/332 V secondary, and 60 Hz operation with a 150 °C rise. Aluminum windings paired with the DT-3 dry-type design reduce heat buildup and EMI, improving drive efficiency and reliability in continuous-duty applications such as conveyors and packaging lines.
Industries with demanding automation and motor drive needs benefit most, including manufacturing, packaging, material handling, and CNC-driven equipment. The isolation feature reduces EMI and voltage transients, protecting sensitive drives and control electronics, while the dry-type construction suits compact automation cabinets and floor-mounted drives in harsh environments.
The MD63E96 is UL Listed, providing recognized safety certification for industrial electrical equipment used in distribution and control applications. This certification supports compliance on plant floors and in manufacturing environments, giving buyers confidence in safety and reliability for motor drive installations and panel assemblies.
This dry-type transformer requires minimal maintenance compared with oil-filled units, reducing servicing downtime. Its aluminum windings resist corrosion, and WS39 weather shield enhances durability in challenging environments. Combined with Eaton’s standard warranty terms, this translates to lower total cost of ownership, predictable performance, and longer intervals between service events for automation projects.
