FAQs
When deploying XDT3E9 in Class I Division 2 environments, plan for proper area classification and service access. Confirm the 600 Vac primary and 480Y/277 Vac secondary compatibility with existing equipment, and use the resin-encapsulated, copper-winding design to minimize moisture ingress. Follow the SP3D design package and installation sheets for wiring layouts, mounting methods, and clearances. Ensure appropriate grounding and enclosure integrity to maintain compliance and safety.
The 9 kVA rating defines the maximum load the transformer can handle continuously, while 60 Hz sets the operating frequency for distribution systems common in North America. Copper windings and resin encapsulation contribute to low losses and stable voltage conversion, improving overall efficiency. This combination supports reliable motor feeders and control circuits without excessive heat buildup or voltage drop under typical process loads.
Yes. The XDT3E9 is designed for hazardous-location environments (Class I, Division 2) with a NEMA 3R enclosure and resin-encapsulated windings, delivering reliable, protected voltage transformation. Its 600 Vac to 480Y/277 Vac, three-phase output suits process equipment, control panels, and instrumentation in chemical plants and refineries where safety and durability are critical.
The XDT3E9 complies with NEC/CEC standards and is rated for Hazardous/Classified Locations with Class I, Division 2. It uses a NEMA 3R enclosure for environmental protection. Documentation and Canadian certifications are available via UL/Canadian certification references, and installation guidelines reference NEC/CEC compliance and hazardous-location practices.
Maintenance benefits include reduced moisture-related degradation due to resin encapsulation and copper windings, which lowers failure risk and downtime. The dry-type design has no oil to leak, simplifying maintenance and safety checks. ROI improves through dependable operation, extended service life, simplified procurement via SP3D resources, and faster commissioning in hazardous locations.
