Eaton Crouse-Hinds XTT3F75X-50C Dry-Type Transformer - 4X
Part Number: XTT3F75X-50C
Quick Summary
The XTT dry-type transformer delivers safe, efficient power distribution for hazardous industrial locations. Maintenance teams frequently battle compliance gaps and unexpected downtime when installing equipment in classified spaces. This model aligns with NEC/CEC standards, offers Class I, Division 2 hazardous-area rating, and a rugged NEMA 4X enclosure. The resin-encapsulation and copper windings support durability in harsh environments, while the 316 stainless steel enclosure resists corrosion. With 75 kVA capacity and a 480 VAC primary, the XTT3F75X-50C helps reduce space, installation costs, and maintenance overhead. Designed for hazardous/classified locations with NEC/CEC compliance and UL recognition in many markets, it supports safer design reviews. Outdoors or in process areas, its resin-encapsulated construction and NEMA 4X enclosure simplify procurement and commissioning, delivering tangible business value.

Resin encapsulated construction provides moisture and dust protection, sealing windings and reducing corona risk in harsh environments. This translates to longer service life, fewer unplanned maintenance events, and lower spare-part inventories. In hazardous locations the encapsulation also helps maintain performance under vibration and temperature cycling, improving uptime in critical process areas. The unit’s 75 kVA, 60 Hz three-phase design enables scalable power distribution for mid-size plant loads, supporting future expansion without transformer replacement. With a 480 VAC primary and 400Y/231 VAC secondary, it aligns with common industrial motor and control voltages, reducing wiring complexity and installation time. The 316 stainless steel enclosure offers corrosion resistance in chemical plants and outdoor installations, extending service life in aggressive environments. Copper windings maximize efficiency, lowering operating losses and contributing to favorable total cost of ownership. The transformer’s compact footprint (35.1 in L × 26 in W × 26.64 in H) and 1430 lb weight balance robust protection with practical installation in space-constrained areas. The equipment’s NEC/CEC standards alignment, Class I Division 2 rating, and 4X enclosure support regulatory compliance and site safety.

FAQs
Install on a solid, level mounting surface with the exact footprint of 35.1 in by 26 in and allow clearance for service. Use appropriate mounting hardware and seismic restraints if required by facility standards. Route 480 VAC primary and 400Y/231 VAC secondary conductors with proper insulation, strain relief, and NEC-compliant protective devices. Ensure access for regular maintenance and inspection per local regulations.
Class I Division 2 rating allows safe operation in spaces where flammable gases or vapors may be present, provided the installation adheres to NEC/CEC requirements. This reduces ignition risk in critical process environments such as chemical plants and refineries, enabling broader equipment deployment while maintaining safety and compliance.
The product adheres to NEC/CEC standards, carries a NEC hazardous rating of Class I Division 2, and uses a NEMA 4X enclosure for enhanced ingress protection. UL documentation supports U.S. and Canadian compliance. Verify the specific UL reports and documentation with procurement for site-specific approval.
Resin encapsulation provides moisture and dust resistance, sealing windings and reducing corona risk in harsh environments. This yields longer service life, fewer unplanned maintenance events, and lower spare-part inventories. In hazardous locations the encapsulation also helps maintain performance under vibration and temperature cycling, boosting uptime in critical process areas.
Although the unit is heavy, its durability and low operating losses from copper windings deliver favorable lifecycle costs. The robust enclosure and regulatory compliance reduce downtime risk and maintenance shuffles, while standard documentation and accessories simplify commissioning. Over the transformer’s life, customers can expect predictable maintenance needs and improved process reliability.
