Eaton XDT1A3 Dry-Type Transformer - Class I, Division 2
Part Number: XDT1A3
Quick Summary
XDT1A3 dry-type transformer powers hazardous-area equipment with safe, reliable 480 VAC to 120/240 VAC conversion for industrial facilities. In practice, engineers face the challenge of maintaining regulatory compliance while controlling spares, downtime, and maintenance costs. With NEC/CEC compliance, a Class I, Division 2 rating, and a NEMA 3R enclosure, it supports safe operation in hazardous environments. The resin-encapsulated copper windings and painted steel enclosure simplify installation and service, delivering lifecycle value for power management in demanding facilities and enabling robust integration with existing 480 V plant infrastructure and 120/240 V loads.

FAQs
Plan for a compliant mounting location with a 3R enclosure, provide proper ventilation, follow NEC/CEC routing for 480 VAC primary and 120/240 VAC secondary wiring, and confirm proximity to 480 VAC feeders. Ensure secure mounting, required clearance, and proper grounding per local standards to maintain hazardous-location ratings.
The XDT1A3 is a single-phase transformer rated at 3 kVA with a 480 Vac primary and 120/240 Vac secondary, operating at 60 Hz. It features copper windings and resin encapsulation within a painted steel enclosure, suitable for hazardous locations with Class I, Division 2 compliance.
Yes. Its resin-encapsulated copper windings, 3R enclosure, and Class I Division 2 rating make it appropriate for control panels, instrumentation, and safety circuits in hazardous locations, while providing reliable voltage transformation from 480 VAC to 120/240 VAC.
It carries NEC/CEC compliance with a Class I Division 2 hazardous-location rating and a NEMA 3R enclosure. Certification scope also includes area classifications for hazardous/classified locations, with Canadian certifications referenced in Eaton documentation.
The resin-encapsulated copper-winding design and steel enclosure help resist moisture ingress and environmental stress, reducing maintenance frequency and extending service life. This translates to lower downtime, fewer spare-part needs, and improved total cost of ownership in demanding facilities.
