Resin-encapsulated construction provides rugged mechanical protection and moisture resistance, reducing field failures and maintenance costs in harsh environments. Business impact: lower total cost of ownership and enhanced uptime in utility rooms and hazardous areas. Application: ideal for critical control panels and power distribution in industries with stringent safety requirements. Copper windings deliver improved thermal efficiency and electrical performance, enabling reliable operation at elevated ambient temperatures and reducing heat-related losses. Application: supports compact cabinet design and energy-aware plant modernization projects. The 316 stainless steel enclosure adds corrosion resistance for washdown and chemical-exposure zones, extending service life in harsh facilities. Benefit: longer intervals between upkeep and fewer enclosure-related faults. Three-phase 60 Hz operation with 480 Vac primary and 400Y/231 Vac secondary enables straightforward integration with common industrial electrical distributions, enabling quick commissioning and scalable motor control. Application: suitable for motors, drives, and control circuits in manufacturing lines and process plants. Its compact footprint—19.13 in long, 14.69 in high, 11.88 in wide—and 200 lb weight support straightforward installation in crowded electrical rooms or retrofit projects with limited space. Benefit: easier handling, reduced installation time, and fewer structural concerns. Compliance-ready design meets NEC/CEC and Class I Division 2 hazardous-area requirements with NEMA 4X enclosure protection, ensuring safety, regulatory alignment, and audit readiness across plant facilities. Application: simplifies procurement and documentation for regulated environments while supporting ongoing maintenance programs. Industry notes: resin-encapsulated dry-type transformers such as XTT variants are favored in hazardous locations for their moisture resistance, robust insulation, and improved reliability over conventional oil-filled models, which translates to lower lifecycle risk in volatile industrial settings.
