The resin-encapsulated design, combined with copper windings, minimizes moisture ingress and arc fault risk, delivering safer operation in harsh environments. Business impact: reduced maintenance cycles and longer service intervals, translating to lower total cost of ownership. Application: ideal for hazardous-location installations in chemical plants, refineries, and oil & gas facilities where reliability matters most. The 75 kVA rating with a 480 Vac primary and 208Y/120 Vac secondary enables seamless integration with standard plant power distribution, improving overall system efficiency and reducing wiring complexity. By meeting NEC/CEC standards and Class I, Division 2 requirements, the transformer supports compliant procurement and faster commissioning, minimizing project delays. Application-ready with a NEMA 3R enclosure, it resists weather and dust ingress, protecting critical equipment in outdoor or partially protected spaces. The painted steel cabinet complements existing plant enclosures, aiding retrofit projects and spare parts compatibility, while copper windings enhance thermal performance under load. In practice, installers benefit from clear mounting dimensions and resin-encapsulated protection that reduces risk during startup and routine maintenance. These features collectively enable safer, more reliable operations in demanding industrial environments.

FAQs
For safe installation in hazardous locations, ensure compliance with Class I, Division 2 guidelines and NEC/CEC standards. Use a NEMA 3R-rated painted steel enclosure, verify proper clearance around the transformer, and follow Eaton installation sheets. Orientation, ventilation, and proper mounting hardware are essential to maintain coating integrity and enclosure protection while enabling accessible service access.
XDT3B75 delivers 75 kVA with a 480 Vac primary and 208Y/120 Vac secondary at 60 Hz, using copper windings and resin encapsulation for robust insulation. This configuration supports efficient load handling and heat dissipation, reducing stray losses and maintenance needs. Its solid construction helps maintain voltage stability under varying load conditions typical in industrial automation.
Yes. The transformer is designed for hazardous/classified locations and meets NEC/CEC requirements with Class I, Division 2 rating and NEMA 3R protection. Resin encapsulation and copper windings provide reliable insulation in corrosive or moist environments, making it well-suited for chemical processing plants and oil refineries where safety and reliability are critical.
XDT3B75 aligns with NEC/CEC standards and carries a Class I, Division 2 hazardous location rating along with NEMA 3R enclosure protection. Canadian certifications are referenced in supporting UL reports, ensuring compliance for cross-border installations. These certifications simplify procurement, permit approvals, and regulatory audits across multi-site industrial operations.
The resin-encapsulated design reduces moisture ingress and maintenance, while copper windings offer high efficiency and thermal performance under load. Long service life and fewer oil-related concerns translate to lower lifecycle costs, reduced downtime, and faster project ROI. Compatibility with standard plant power systems also minimizes installation risk and accelerates commissioning.
