Encapsulation enhances safety by containing insulation and protecting windings in hazardous environments, reducing ignition risk and simplifying regulatory compliance. This directly lowers downtime and maintenance costs while supporting consistent performance in demanding applications. The 5 kVA, 1-phase design delivers reliable power conversion from 240/480 VAC to 120/240 VAC, enabling robust control panel operation in distributed automation and process equipment. Copper windings improve thermal conductivity and voltage regulation, delivering predictable output even under load fluctuations. The unit’s 50/60 Hz compatibility ensures broad regional usability and seamless integration with existing Eaton or third-party power distribution infrastructures. Compact encapsulation also simplifies installation in tight electrical rooms and enclosures, reducing space requirements and wiring complexity. Reliability insights from field deployments show reduced fault rates and longer service intervals under continuous operation.

FAQs
The Z20N11B05CU is designed for hazardous locations where protection from ignition sources is critical. Encapsulation helps contain insulation, reducing risk of flame propagation and enabling safer operation in industrial spaces such as chemical, oil and gas, and other high-risk environments. Always verify regional certifications with the manufacturer.
This unit is a 5 kVA, 1-phase transformer with a primary voltage of 240/480 VAC and a secondary voltage of 120/240 VAC. It operates at 50/60 Hz and uses copper windings with encapsulation to protect internal components. Thermal rise is designed around safe operation with solid voltage regulation under load.
Yes. The encapsulated design is intended to fit with typical low-voltage power distribution and control panels used in industrial automation. Copper windings and robust enclosure provide protection against contaminants, enabling straightforward mounting and wiring within standard panel footprints while maintaining safety margins in hazardous areas.
Certification status for this model is listed as manufacturer-confirmed. In practice, similar encapsulated transformers commonly pursue CE labeling for EU compliance, IP enclosure ratings for ingress protection, and regional safety approvals (UL/CSA in North America). Always confirm exact certifications with Eaton for your project’s jurisdiction.
The encapsulated design reduces maintenance frequency and minimizes downtime in hazardous environments, leading to lower lifecycle costs. Field reliability of copper-wound, encapsulated transformers supports longer service intervals, fewer fault-induced outages, and predictable performance, which collectively improve uptime and overall project ROI in continuous-process and automation applications.
