Resin-encapsulated construction with copper windings delivers rugged insulation and moisture resistance, reducing moisture-related breakdowns in harsh environments. This translates to longer mean time between failures (MTBF) and lower maintenance costs, especially in chemical and petrochemical facilities where exposure to vapors can degrade windings. The rugged design supports dependable operation in hazardous locations, enabling safer, more reliable power delivery to critical loads. In practice, engineers gain improved uptime and reduced emergency service calls for mission-critical equipment in process plants and refineries. The transformer’s compact form factor and resin encapsulation also simplify installation in tight electrical rooms, while maintaining high insulation integrity in dusty or humid environments.

FAQs
The XDT3B30X is designed for Class I, Division 2 environments and has a NEMA 4X enclosure, which supports outdoor or washdown conditions. When installing, ensure the unit is mounted in a location with appropriate clearance for cooling and access to wiring terminations, and follow NEC/CEC guidelines and Eaton installation sheets to maintain compliance and insulation integrity.
The transformer converts 480 Vac primary to 208Y/120 Vac secondary in a three-phase configuration with 60 Hz operation and copper windings. Resin encapsulation reduces moisture ingress, contributing to stable regulation and improved efficiency under load. This supports reliable voltage transformation for motor starters, controls, and sensitive equipment without excessive heat buildup.
Yes. With a 4X enclosure rating and hazardous-location compliance, the XDT3B30X is designed for outdoor installations and challenging environments. Its 316 stainless steel construction and resin-encapsulated winding design provide corrosion resistance and protection against dust and moisture, making it appropriate for outdoor substations and chemical plant yards.
The XDT3B30X meets NEC/CEC standards and carries a Class I Division 2 hazardous-location rating, along with a NEMA 4X enclosure. UL certification references are available in the UL reports and Eaton documentation, complemented by installation and datasheet references for design validation and regulatory compliance.
The resin-encapsulated copper-windings design reduces moisture-related failures and lowers maintenance cycles, contributing to higher MTBF and reduced downtime. The robust 316 stainless steel enclosure and 4X rating simplify outdoor deployments, while NEC/CEC compliance minimizes regulatory risk, delivering improved uptime and total cost of ownership over the transformer’s service life.
