FAQs
When installing the XDT3B45 in hazardous locations, ensure proper area classification (Hazardous/Classified Locations) and secure mounting to support the 811 lb weight. Verify 480 Vac primary and 208Y/120 Vac secondary wiring with copper conductors, maintain adequate clearance, and follow NEC/CEC guidelines. Use a suitable enclosure rating (NEMA 3R) for weather exposure and protect terminations from vibration or impact during maintenance.
Key specs include 45 kVA rating, three-phase, 60 Hz, 480 Vac primary, and 208Y/120 Vac secondary. The transformer uses copper windings and is resin-encapsulated, with a painted steel enclosure. Dimensions are 28.17 in L, 26.49 in H, 14.66 in W, and weight about 811 lb, making it suitable for moderate footprint installations in control rooms or outdoors in protected areas.
Yes. The XDT3B45 is designed for hazardous/classified locations with Class I, Division 2 ratings and NEC/CEC compliance, plus a NEMA 3R enclosure. Its resin encapsulation and copper windings support reliable operation in chemical environments, while the 480 Vac to 208Y/120 Vac output fits standard control panels and automation equipment.
The transformer carries NEC/CEC compliance, a Class I, Division 2 hazardous-location rating, and a NEMA 3R enclosure. These certifications facilitate regulatory approvals, enable safer operation in hazardous environments, and support compliance during audits and procurement reviews for industrial facilities.
Resin encapsulation protects windings from moisture, dust, and chemical exposure, reducing insulation degradation and common field failures. This translates to lower maintenance costs, longer mean time between failures (MTBF), and improved reliability for critical processes in harsh environments such as chemical plants and oil refineries.
