Resin-encapsulated construction provides moisture and dust resistance, reducing corrosion risks and maintenance needs in hazardous locations; this translates to lower downtime and longer service intervals for critical loads in harsh environments. The 150 kVA, three-phase configuration with a 600 Vac primary and 208Y/120 Vac secondary delivers robust, stable voltage transformation for motors, drives, and control systems, boosting overall plant efficiency and reducing equipment stress. A 316 stainless steel enclosure complements the resin encapsulation by offering corrosion resistance in chemical or outdoor settings, enabling reliable operation in demanding facilities. Copper windings enhance electrical efficiency and heat management, contributing to lower operating temperatures and improved lifetime performance. NEMA 4X protection and NEC/CEC compliance simplify installation and regulatory alignment, while footprint and weight considerations inform proper mounting and hoisting planning for large installations. This transformer integrates with standard low-voltage distribution gear and Eaton’s design documents for streamlined project workflows.

FAQs
When installing XTT3D150X in hazardous locations, ensure proper indoor dry-area mounting with adequate clearance for heat dissipation. The unit’s 316 stainless steel housing and resin encapsulation reduce environmental ingress, while the 4X enclosure supports corrosion resistance. Plan hoisting and anchoring around its 2677 lb weight, and verify NEC/CEC compliance and Class I, Division 2 classification with local authorities having jurisdiction.
XTT3D150X is a three-phase transformer rated at 150 kVA, with a 600 Vac primary and 208Y/120 Vac secondary. It operates at 60 Hz and uses copper windings for high efficiency and stable voltage. The resin-encapsulated design improves moisture and dust resistance, while 316 stainless steel ensures durability in demanding environments.
Yes. The XTT3D150X is specifically designed for Hazardous/Classified Locations with NEC/CEC compliance and a Class I, Division 2 rating. Its NEMA 4X enclosure and resin-encapsulated construction make it well-suited for oil and gas facilities, chemical processing, and other harsh environments requiring robust protection and reliable power transformation.
The XTT3D150X carries NEC/CEC standards, a Class I, Division 2 hazardous rating, and a NEMA 4X enclosure. These certifications support safe operation in hazardous locations, enable regulatory alignment for project documentation, and simplify approvals with inspection agencies. Additional Eaton resources (spec sheets, catalogs, and installation guides) aid in compliant deployment and ongoing maintenance.
The resin-encapsulated, dry-type design minimizes moisture ingress and dust exposure, reducing maintenance frequency and downtime. Copper windings and 316 stainless steel construction contribute to higher efficiency and longer service life, lowering energy losses and replacement costs. For asset-intensive facilities, these features translate to predictable uptime, easier regulatory adherence, and a favorable total cost of ownership.
