Resin encapsulation with copper windings provides superior moisture resistance and thermal stability, reducing maintenance intervals and improving uptime in dusty, humid, or aggressive environments. This translates to lower total cost of ownership and fewer unplanned outages during peak operating conditions while maintaining voltage integrity for critical loads. The unit operates at 60 Hz with a 45 kVA rating, 480 Vac primary and 400Y/231 Vac secondary across a three-phase configuration, delivering consistent power to motors and control circuits with minimal voltage drop. A painted steel enclosure with NEMA 4 protection enables robust outdoor and indoor installation, meeting Area Classification requirements for Hazardous/Classified Locations and Class I, Division 2 environments. Compliance documentation and practical installation guidance streamline procurement, inspection, and long-term service planning. With compatible XDT/XTT Hazardous Area transformer literature, installation teams benefit from an integrated design and standard mounting footprints, easing retrofits and new builds alike. The unit’s dimensions (32.38 in L × 25.63 in H × 22 in W) and a weight of 835 lb inform rack-and-pad layouts, rigging, and service access, enabling safer lifting practices and efficient maintenance workflows. Designed for industrial automation and power distribution applications, this transformer supports reliable, compliant operation in challenging facilities while aligning with procurement and lifecycle strategies.

FAQs
Yes. The XTT3F45-50C is designed for 480 Vac three-phase systems with a 400Y/231 Vac secondary and operates at 60 Hz. It is rated for Hazardous/Classified Locations (Class I, Division 2) and features resin encapsulation for moisture resistance, a painted steel enclosure, and NEC/CEC compliance, ensuring seamless integration into compliant power-distribution schemes.
Key certifications include NEC/CEC compliance, a NEMA 4 enclosure, and Hazardous/Classified Locations designation (Class I, Division 2). UL certification references support global use, and Eaton provides corresponding installation literature and documentation to ensure regulatory alignment for hazardous-area transformer applications.
Plan for rigging and stable mounting to support the 835 lb weight, with adequate space for connections and maintenance. The transformer measures 32.38 in long, 25.63 in tall, and 22 in wide, so include pad or enclosure dimensions, clearance for cooling, and access to primary and secondary terminations during installation and service.
Ideal for chemical plants, oil and gas facilities, mining operations, and other processes in hazardous or classified locations. It provides safe voltage transformation from 480 Vac to 400Y/231 Vac for motors, pumps, and control circuits while meeting NEC/CEC and NEMA 4 requirements, ensuring reliable power in challenging environments.
Resin encapsulation enhances moisture resistance and thermal stability, reducing maintenance frequency and extending service life in harsh environments. This lowers spare-part needs and downtime, delivering improved uptime, safety, and lower total cost of ownership for critical power distribution systems in hazardous locations.
