Copper windings with resin encapsulation provide robust insulation and thermal stability, enabling longer service life in demanding environments. The 50°C ambient rating reduces overheating risk in crowded electrical rooms and outdoor installations, lowering maintenance costs and extending rewinds between servicing events. Copper windings also deliver lower eddy losses, contributing to overall efficiency and energy savings across load profiles. The 480 VAC primary to 400Y/231 VAC secondary configuration supports common industrial power distribution schemes, simplifying integration with existing switchgear and panelboards while the 60 Hz rating aligns with standard utility grids. This enables efficient control circuits and motors without custom gear purchases, improving project lead times. Hazardous-location readiness is built in with NEC/CEC compliance, Class I, Division 2 certification, and a NEMA 4 enclosure, reducing regulatory risk and enabling safer installations. The painted steel enclosure provides rugged protection in harsh environments, while resin-encapsulated windings offer moisture resistance and vibration tolerance. Dimensions of 26.13 in L, 21.88 in H, 19.75 in W with a 520 lb weight inform installation planning and mounting in constrained spaces.

FAQs
The XTT3F30-50C is a dry-type transformer that steps down 480 VAC to 400Y/231 VAC for three-phase power networks in hazardous locations. It employs resin-encapsulated copper windings and a 50°C ambient rating, with a NEMA 4 enclosure and Class I, Division 2 certification. This combination enables safe, reliable power distribution for chemical plants, refineries, and other sensitive environments while simplifying compliance documentation.
Yes. The XTT3F30-50C is designed to meet NEC/CEC requirements and carries Class I, Division 2 hazardous-location ratings along with a NEMA 4 enclosure. This alignment helps streamline regulatory approvals, reduce audit risk, and support standardization across facilities that demand rigorous electrical safety and performance.
The transformer footprint is 26.13 inches long, 21.88 inches high, and 19.75 inches wide, with an overall weight of 520 pounds. These dimensions and mass inform mounting arrangements, clearance planning, and handling during installation in constrained spaces or elevated enclosures typical of process facilities.
Comprehensive engineering resources are available, including SP3D design packages, product catalogs, brochures, installation instructions, and UL certification reports. Additional Eaton specification sheets and datasheets support procurement, qualification, and commissioning, helping verify compliance with internal standards and external codes.
By combining a rugged resin-encapsulated copper-windings design, NEC/CEC compliance, and a Class I, Division 2 rating within a NEMA 4 enclosure, the XTT3F30-50C reduces downtime, lowers maintenance costs, and speeds regulatory approvals. The 480/400Y/231 V, 60 Hz three-phase configuration also minimizes integration effort with existing plant power systems.
