Dry-type distribution, DT-3 design with three-phase operation provides inherent safety and reliable cooling for continuous motor drive service. The 63 kVA rating supports demanding loads while keeping enclosure temperatures manageable, reducing thermal wear and unplanned downtime. This combination is ideal for modern production lines where uptime and safety matter most. 208 V primary to 230Y/133 V secondary alignment enables direct compatibility with common motor drives and 60 Hz systems, minimizing adapters and commissioning time while simplifying panel integration. Tap changes at +5% FCAN and -5% FCBN allow voltage compensation for fluctuating feeds, reducing voltage drop, improving drive performance, and lowering nuisance trips in sensitive equipment. Aluminum windings and WS39 weather shield extend service life in harsh environments, supporting outdoor or industrial installations with reduced maintenance needs. The 914D frame with footprint dimensions of 22 in length, 29 in width, and 39 in height, plus a 480 lb weight, simplify mounting, enclosure fit, and replacement planning for retrofit projects. UL Listed certification and Eaton’s one-year warranty provide risk mitigation and regulatory alignment, while the dry-type ventilation design supports fast, safe installation and predictable service life.
