Resin-encapsulated housing with a 316 stainless steel enclosure provides superior moisture and chemical resistance, reducing corrosion risk and field maintenance in harsh locations. This construction minimizes ingress paths and keeps insulation intact under demanding ambient conditions, contributing to longer service intervals and lower lifecycle costs. The XTT3F112X-50C is well-suited for hazardous-area control panels, process skids, and automation cabinets that demand rugged reliability. Copper windings deliver efficient current transfer and better thermal management, lowering copper losses and improving voltage regulation at load. Combined with a robust insulation system, this translates into more stable performance for sensitive control electronics and motor drives, even when ambient temperatures approach 50°C. In applications like automated lines and packaging machines, this means fewer trips to the maintenance shelf and more uptime. With a 112.5 kVA rating and 480 Vac primary / 400Y/231 Vac secondary, the transformer supports flexible feeder configurations and easy integration with existing power systems. The three-phase design reduces voltage imbalance and supports scalable automation architectures, from MCCs to PLC panels. This compatibility simplifies procurement, reduces spare-part inventories, and shortens commissioning times for new lines. The unit is designed for hazardous locations, carrying NEC/CEC compliance, a Class I, Division 2 rating, and NEMA 4X protection. Resin encapsulation and 50°C ambient capability further enhance safety and reliability in environments with dust, moisture, and potential exposure to chemicals. Engineers gain regulatory peace of mind and easier approvals during audits, while operations benefit from safer start-ups and consistent performance. Physical dimensions and weight—36.63 in long, 31.38 in high, 30.5 in wide, and approximately 2652 lb—facilitate accurate installation planning and structural compatibility. The robust 316 stainless steel shell supports long service life in harsh environments and pairs with standard mounting schemes used in industrial automation. Overall, the XTT3F112X-50C offers a proven, maintenance-friendly solution for critical power distribution in hazardous-area facilities.
