Eaton Crouse-Hinds XTT3F3X-50C Dry-Type Transformer - 4X
Part Number: XTT3F3X-50C
Quick Summary
XTT3F3X-50C dry-type transformer reliably isolates and powers control gear in hazardous locations. Engineers often struggle to find equipment that withstands chemicals, dust, and regulatory constraints while delivering steady 3 kVA power. This unit meets NEC/CEC compliance, carries a Class I, Division 2 rating, and a NEMA 4X enclosure for rugged installation. Its 60 Hz operation, copper windings, and 50°C ambient rating pair with 316 stainless steel construction to minimize maintenance and corrosion risk. With 480 Vac primary and 400Y/231 Vac secondary, it integrates smoothly into standard industrial panels, reducing wiring complexity. The result is safer, compliant power with lower lifecycle costs for automation projects in hazardous environments.

Three-phase, 3 kVA rating provides compact, efficient power transformation for distributed control systems, reducing cabinet footprint and wiring complexity. This transformer supports 480 Vac primary and 400Y/231 Vac secondary, enabling straightforward integration with standard industrial panels and equipment in modern automation architectures. Resin encapsulation protects windings from moisture, dust, and vibration, delivering improved reliability in harsh environments and reducing unplanned downtime. Copper windings enhance thermal performance and efficiency, contributing to lower energy losses and cooler operation under load. A 316 stainless steel enclosure delivers superior corrosion resistance, expanding service life in challenging environments such as chemical plants and off-shshore facilities. With NEMA 4X enclosure and NEC/CEC compliance, installation meets robust safety standards while Class I, Division 2 rating minimizes regulatory risk for hazardous-location projects. The compact footprint and favorable weight (145 lb) simplify handling and retrofits, while the 50°C ambient rating ensures dependable operation in warm spaces. Industry practitioners benefit from reduced maintenance intervals, faster installation, and improved panel reliability when integrating this XTT transformer into power distribution and control systems.

FAQs
The XTT3F3X-50C is designed for hazardous/classified locations with a Class I Division 2 rating and a NEMA 4X enclosure. Use in clean, dry, and ventilated spaces within chemical plants or oil and gas facilities is supported. Plan for a 480 Vac to 400Y/231 Vac three-phase connection, and ensure enclosure mounting does not obstruct ventilation or access to terminal connections.
This transformer carries NEC/CEC compliance and a Class I, Division 2 rating, along with a NEMA 4X enclosure. These certifications ensure safe operation in hazardous areas and simplify documentation for compliant panel assemblies and routine inspections.
Primary voltage is 480 Vac, and secondary voltage is 400Y/231 Vac. Three-phase operation at 60 Hz makes it ideal for distributing controlled power to automation panels, motor starters, and instrumentation in hazardous environments while maintaining stable voltage to sensitive equipment.
Resin encapsulation protects copper windings from moisture, dust, and mechanical vibration, reducing insulation degradation and corrosion risk. This translates to lower maintenance requirements, longer service life, and better performance consistency in challenging environments.
Dimensions are 15.88 in (L) × 15.39 in (H) × 9.88 in (W) with a weight of 145 lb. This compact, heavy-duty form factor facilitates retrofit or new installations in standard electrical rooms and control cabinets without excessive space planning.
