Eaton Crouse-Hinds XDT1A1 Transformer - Class I, Div 2
Part Number: XDT1A1
Quick Summary
XDT1A1 dry-type transformer provides safe voltage conversion for hazard-location control panels. Engineers often struggle to meet Class I Division 2 requirements without compromising footprint or serviceability. It carries NEC/CEC compliance, UL certifications, and a NEMA 3R enclosure, supporting reliable performance in harsh environments. With copper windings, resin encapsulation, and a painted steel enclosure, this transformer helps reduce lifecycle costs while enabling compact, compliant installations. This combination of compact size, rugged construction, and hazardous-location readiness translates to quicker installations and reduced project risk. It is particularly suitable for control houses, motors, and power distribution in chemical, oil, and gas processing environments.

The XDT1A1 delivers a 1 kVA single-phase output with a 480 Vac primary and 120/240 Vac secondary at 60 Hz, using copper windings and resin encapsulation. This combination improves thermal performance, enhances impedance stability, and reduces secondary voltage drop, delivering reliable control power for panels and motor starters in hazardous locations. The painted steel enclosure plus a NEMA 3R rating provides weather and impact resistance, allowing confident outdoor or semi-enclosed installations while maintaining safety in classified areas. NEC/CEC compliance with Class I Division 2 certification minimizes regulatory risk and accelerates project approvals, enabling faster commissioning on site. The compact footprint (5.9 in L / 11.3 in H / 5.7 in W) and a 35 lb weight enable straightforward mounting in space-constrained panels and compact cabinets, simplifying retrofits and new builds alike. Resin encapsulation protects windings from moisture and contaminants, reducing maintenance cycles in harsh industrial environments. Compatibility with SP3D design packages, installation sheets, and Eaton literature supports CAD-ready integration and accurate field installations for controlled electrical distribution in petrochemical and manufacturing facilities.
