Feature → Business Impact → Application: 45 kVA rating with 480 VAC primary and 400Y/231 VAC secondary enables one transformer to support multiple feeders, reducing equipment count and simplifying panel design in industrial facilities. This improves install time and lowers total cost of ownership in hazardous-area sites where reliability and space are at a premium. The resin-encapsulated construction with copper windings enhances thermal performance and electrical integrity, delivering higher efficiency and lower hotspot risk in hot environments; ideal for continuous operation in chemical plants or mining sites. 316 stainless steel housing combined with a 50°C ambient rating delivers superior corrosion resistance and longevity, cutting maintenance cycles and downtime in offshore platforms and washdown-heavy plants. NEC/CEC compliance, Class I, Division 2 rating, and NEMA 4X enclosure provide documented protection for hazardous locations, facilitating design approvals and safer commissioning. The compact footprint (32.38 in L × 22 in W × 25.63 in H) and 915 lb weight support straightforward mounting and service access, reducing installation complexity in existing utility rooms. Documentation such as SP3D packages and Eaton specification sheets accelerates design validation and procurement, mitigating risk during project execution.

FAQs
The XTT3F45X-50C is designed for hazardous and classified locations, meeting NEC/CEC requirements with Class I, Division 2 rating and a NEMA 4X enclosure. Its 316 stainless steel housing and resin-encapsulated construction make it suitable for chemical plants, oil and gas facilities, and other environments that demand robust protection against dust, moisture, and corrosive exposure.
This transformer provides a 45 kVA rating with a 480 VAC primary and a 400Y/231 VAC secondary in a three-phase 60 Hz configuration. It integrates with standard switchgear and distribution panels supporting 480 V inputs, enabling reliable step-down distribution to secondary distribution or motor control circuits in industrial plants.
Resin encapsulation offers enhanced moisture and vibration resistance, while copper windings deliver high efficiency and lower resistive losses. Together, they reduce insulation stress, improve thermal management, and extend service life in harsh environments, lowering unplanned downtime and maintenance costs in demanding applications.
With dimensions of 32.38 in L, 22 in W, 25.63 in H and a weight of 915 lb, plan for adequate floor/load capacity and clearance for servicing. The unit’s footprint is compatible with standard electrical rooms and outdoor locations, but ensure ventilation, seismic considerations, and compatible mounting hardware are accounted for in the layout.
Certification and technical documentation include SP3D design packages, XDT/XTT literature, and UL certification references, plus Eaton specification sheets. Access pages covering hazardous-area transformers, installation instructions, and datasheets to support design validation, procurement, and compliance during project development.
