The XTT3F112-50C delivers 112.5 kVA at 60 Hz, enabling a single unit to support multiple feeders and reduce transformer count in the plant, which lowers maintenance overhead and saves floor space. With a 480 Vac primary and a 400Y/231 Vac secondary, it integrates smoothly with common factory power distributions and industrial controls, simplifying panel design and wiring. Resin encapsulation protects windings from moisture, dust, and vibration, reducing insulation failures in challenging environments and extending service life. Copper windings offer high conductivity and improved efficiency, contributing to lower heat generation and energy costs over the life of the installation. A painted steel enclosure rated for 50°C ambient and a rugged three-phase construction enhance durability in hot, harsh industrial settings. Area classification for hazardous/classified locations, NEC/CEC compliance, and a NEMA 4 enclosure provide regulatory assurance and safer operation in chemical plants, refineries, and production floors. The compact footprint and substantial weight (36.63 in x 30.5 in x 31.38 in; 2652 lb) support sturdy, vibration-resistant mounting and reliable long-term service.

FAQs
Install the XTT3F112-50C in accordance with NEC/CEC requirements for Class I, Division 2 locations. Ensure proper enclosure integrity (NEMA 4), secure mounting on vibration-minimized supports, and adequate clearance for cooling. Connect three-phase 480 Vac service to the primary terminals and route 400Y/231 Vac outputs to downstream loads with properly rated fuses or breakers. Use resin-encapsulated construction to minimize moisture effects and maintain insulation reliability in harsh environments.
Key specs include 112.5 kVA at 60 Hz, three-phase configuration, primary voltage 480 Vac, secondary voltage 400Y/231 Vac, copper windings, and resin encapsulation. The enclosure is painted steel with a 50°C ambient rating, suitable for hazardous areas. It complies with NEC/CEC standards and has a NEMA 4 enclosure rating for protection against dust and water ingress.
Yes. The XTT3F112-50C is designed for hazardous/classified locations and carries NEC hazardous rating Class I, Division 2. Paired with its NEMA 4 enclosure and resin encapsulated construction, it provides robust electrical isolation and protection against moisture, dust, and corrosive atmospheres typical of chemical plants and oil refineries.
It carries NEC/CEC standards compliance for hazardous locations, Class I, Division 2 rating, and a NEMA 4 enclosure. Canadian certifications are referenced in the supporting documentation, and UL/CSA-related listings are available through the referenced certification reports and datasheets for verification.
The resin-encapsulated, copper-wound design delivers improved reliability and efficiency, reducing maintenance cycles and energy losses. Its compatibility with 480 Vac/400Y/231 Vac systems simplifies upgrades or expansions in plants, reduces panel space, and minimizes downtime during installation. The rugged enclosure and hazardous-location approvals also lower regulatory risk and heighten safety for operators and maintenance personnel.
