Eaton Crouse-Hinds XDT3B30 Dry-Type Transformer - Hazardous/Classified Locations
Part Number: XDT3B30
Quick Summary
Eaton Crouse-Hinds XDT3B30 dry-type transformer delivers safe, reliable voltage conversion for hazardous-location electrical systems in demanding industrial settings. This 30 kVA unit steps 480 Vac down to 208Y/120 Vac in a three-phase, 60 Hz configuration, helping control panels and instrumentation run safely at lower voltages. In rugged plant environments, uptime and ignition protection are critical; the XDT3B30’s resin-encapsulated winding and painted steel enclosure minimize moisture ingress, contaminant exposure, and maintenance cycles. Key certifications matter in regulated facilities: NEC/CEC compliance, Class I, Division 2 hazardous ratings, and NEMA 3R enclosure support installation in indoor and exposed outdoor locations. For engineers and procurement, the model also integrates with standard Eaton/Crouse-Hinds power-distribution ecosystems, improving compatibility and total-cost-of-ownership.

FAQs
For XDT3B30 installations in Hazardous/Classified Locations, verify area classification and ensure compliance with NEC/CEC requirements. Mount in a protected area or NEMA 3R enclosure, maintain proper clearances for cooling, and connect 480 VAC primary to 208Y/120 VAC secondary in a three-phase, 60 Hz configuration. Use approved certified wiring methods and follow manufacturer installation instructions to minimize ignition risks and maximize uptime.
The XDT3B30 is a 30 kVA resin-encapsulated dry-type transformer with a 480 VAC primary and 208Y/120 VAC secondary. It operates at 60 Hz and is a three-phase unit with copper windings. These specifications support safe, efficient step-down power for control systems, instrumentation, and motors in hazardous locations, while meeting NEC/CEC and Class I, Division 2 requirements.
Yes. The XDT3B30 carries NEC/CEC compliance with a Class I, Division 2 hazardous-location rating and an area classification of Hazardous/Classified Locations. It also features a NEMA 3R enclosure suitable for indoor and weather-exposed installations. This combination supports regulatory approvals, audits, and safer operation in regulated facilities such as chemical plants and refineries.
Typical applications include powering control panels, instrumentation, and drives in hazardous environments. The transformer steps down 480 VAC to 208Y/120 VAC for smart sensors and PLCs while maintaining isolation and reliability. It is well-suited for oil and gas facilities, chemical processing plants, and mining operations where compliance and robust performance under harsh conditions are essential.
Maintenance is minimized by the resin-encapsulated windings and durable painted-steel enclosure, which resist moisture and contaminants. Regular checks should include enclosure integrity, connection torque, cooling pathways, and inspection for signs of corrosion or damage. Follow manufacturer guidelines for periodic testing and lubrication of any accessories, and document maintenance to support lifecycle cost optimization.
