Eaton XDT3B9 Dry-Type Transformer - Hazardous Area
Part Number: XDT3B9
Quick Summary
XDT3B9 dry-type transformer is designed to deliver safe, reliable power conversion from 480 Vac to 208Y/120 Vac for hazardous-location control panels in industrial facilities. It addresses common issues with oil-free insulation, resin encapsulation, and rugged steel enclosures by reducing maintenance and fire risk. Certified for NEC/CEC compliance with a Class I, Division 2 rating and a NEMA 3R enclosure, it thrives in damp, dusty environments. The unit combines a 9 kVA, three-phase design with copper windings for efficient operation and compact footprint. This combination supports predictable procurement, tighter control of spare parts, and faster installation for OEMs, integrators, and maintenance teams focused on uptime and safety.

FAQs
XDT3B9 installs under NEC/CEC guidance with Class I Division 2 rating and a NEMA 3R enclosure. Plan for 16.93 in depth, 15.88 in height, and 10 in width, plus a suitable base. Route terminations to compatible panels and follow Eaton wiring torque specs from the installation sheets to ensure compliant, safe connections.
The transformer delivers 9 kVA with a 60 Hz, three-phase design. Primary voltage is 480 Vac and secondary is 208Y/120 Vac, with copper windings and resin encapsulation. These specs support efficient voltage transformation, low copper losses, improved thermal handling, and reliable operation for control circuits and small motors in demanding environments.
Yes. XDT3B9 is suited for hazardous locations (Class I Division 2) and features a NEMA 3R enclosure, making it appropriate for chemical processing and similar environments. With 480/208V distribution, it powers PLCs, sensors, and motor starters while maintaining safety and regulatory compliance in demanding facilities.
XDT3B9 carries NEC/CEC compliance with a Class I Division 2 hazardous rating and a NEMA 3R enclosure for rugged protection. Documentation includes Canadian certification references and UL-listed data; always verify against the latest Eaton datasheet and installation instructions to confirm project-specific compliance.
Resin encapsulation eliminates oil, reducing leak risks and maintenance needs while enhancing thermal stability. Copper windings improve efficiency and reliability, contributing to lower operating costs and longer service life. Availability of SP3D packages, brochures, and installation sheets supports faster procurement, installation, and a favorable total cost of ownership.
