FAQs
When installing XDT3E75 in hazardous locations, ensure the environment is classified as Class I, Division 2 and that the enclosure meets NEMA 3R requirements. Plan for heavy mass handling (approximately 1460 lb) and provide appropriate mounting, clearance for cooling, and compliant conduit routing to maintain CSA/NEC integrity and safe operation in rugged spaces.
XDT3E75 is a three-phase transformer rated at 75 kVA with a 600 Vac primary and 480Y/277 Vac secondary, operating at 60 Hz. Primary current is about 72 A, and secondary current is about 90 A per phase, facilitating accurate load calculations for distribution panels and ensuring proper sizing of protective devices and conductors.
Yes. The XDT3E75 conforms to NEC/CEC standards with a Class I, Division 2 hazardous location rating and a NEMA 3R enclosure, supporting safe operation in classified locations. Additional documentation includes UL certifications and related safety literature for Canada and the U.S., simplifying compliance during audits and inspections.
Resin encapsulation provides moisture, chemical, and vibration resistance, reducing corona and moisture ingress risks in harsh environments. This leads to lower maintenance requirements, higher reliability in hazardous areas, and longer service life, especially in outdoor or chemically active facilities where conventional transformers may struggle.
The resin-encapsulated, sealed design minimizes routine maintenance compared with liquid-filled units, reducing downtime and inspection costs. While the initial investment is higher, the transformer’s durability in hazardous locations, lower leakage risks, and extended service life translate to a favorable total cost of ownership and faster payback in plants with stringent safety and uptime targets.
