FAQs
Installation should follow the XDT1A25 installation sheet and the IF XDT instruction sheet. Position the unit in a ventilated area within a Class I, Division 2 enclosure and connect the 480 Vac primary to the supply and the 120/240 Vac secondary to the local bus. Maintain proper clearances, use copper conductors of the specified gauge, and secure the transformer to a compliant mounting surface. Verify NEC/CEC compliance and UL certification during commissioning.
Key specs include a 25 kVA rating, single-phase configuration, 480 Vac primary, 120/240 Vac secondary, and 60 Hz frequency. The transformer features resin encapsulation with copper windings and a painted steel enclosure. It is designed for hazardous locations with NEC/CEC compliance and a NEMA 3R enclosure to withstand outdoor or damp environments.
Yes. The XDT1A25 is UL certified for hazardous locations and carries NEC/CEC compliance. It is suitable for Class I, Division 2 environments and has a NEMA 3R enclosure rating, making it appropriate for protected outdoor or semi-exposed installations. UL certifications are supported by the provided UL documentation and Eaton’s compliance literature.
This transformer is ideal for control panels, instrumentation, and local power distribution in Class I Division 2 locations. Its 25 kVA capacity supports mid-scale power isolation for devices like motor starters and sensors. The resin-encapsulated construction and copper windings ensure reliable operation in hot or dusty industrial facilities, improving system safety and reducing maintenance needs.
With resin encapsulation and copper windings, maintenance intervals are typically longer due to improved moisture resistance and heat management. Regular electrical checks, enclosure integrity verification, and adherence to installation instructions are recommended. The 13.3 in length, 23.3 in height, 15.8 in width footprint and 409 lb weight should be factored into mounting and accessibility planning during lifecycle management.
