Eaton XTT3E150X Dry-Type Transformer - 4X Hazardous
Part Number: XTT3E150X
Quick Summary
XTT3E150X is a dry-type transformer used for hazardous-location power distribution in industrial facilities. Engineers often struggle with reliable isolation, corrosion resistance, and meeting strict hazardous-location certifications. This unit is NEC/CEC compliant, Class I, Division 2 rated, and features a durable NEMA 4X enclosure suitable for harsh environments. Its resin-encapsulated construction in 316 stainless steel with copper windings delivers robust protection against moisture and contaminants. The 150 kVA rating at 60 Hz, 600 Vac primary, and 480Y/277 Vac secondary supports scalable power distribution while maintaining efficiency. This combination reduces maintenance costs, minimizes downtime, and supports safer, compliant operation across remote or hazardous-site installations.

FAQs
For hazardous-location installations, plan for a crane-assisted lift due to the unit’s 2677 lb weight and its large footprint (30.5 x 31.38 x 36.63 in). Use secure mounting, adequate clearance, and ventilation. Ensure the location is compatible with Class I, Division 2 NEC/CEC requirements and NEMA 4X protection, with wiring to 600 Vac primary and 480Y/277 Vac secondary circuits.
The transformer is 150 kVA, three-phase, with a 600 Vac primary and 480Y/277 Vac secondary, operating at 60 Hz. Copper windings provide high efficiency and thermal performance, while the resin encapsulation and 316 stainless steel enclosure protect windings from moisture and contaminants in challenging environments.
Yes. The unit is designed for hazardous/classified locations with NEC/CEC compliance, Class I, Division 2 rating, and a NEMA 4X enclosure. Its corrosion-resistant stainless steel construction and resin-encapsulated winding reduce maintenance needs in chemical processing, refineries, and other harsh environments while delivering reliable power distribution.
Key certifications include NEC/CEC compliance for hazardous locations, a Class I, Division 2 rating, and NEMA 4X enclosure protection. Canadian UL certification reports are available for reference, supporting regulatory acceptance and safe installation across North American facilities.
Resin encapsulation seals windings against moisture, dust, and corrosive vapors, reducing insulation degradation and maintenance requirements. Combined with copper windings and a stainless steel enclosure, this yields longer service life, lower outage risk, and a favorable total cost of ownership for continuous industrial operation.
