Type
Encapsulated transformer
Encapsulation and HazLoc design → Enhances safety and compliance → Best for classified environments. This feature reduces the risk of arcing, moisture ingress, and dust intrusion, allowing equipment to operate in Class I Division 2 zones with greater confidence. In practice, control panels in chemical plants or refineries benefit from fewer enclosure penetrations and lower maintenance overhead when using encapsulated transformers. 25 KVA rating and single-phase output → Supports reliable panel power and minimizes transformer crosstalk in compact control architectures → Ideal for machine controls, instrument racks, and small distribution sub-panels. 480-120/240 secondary and 115C rise → Delivers predictable voltage conversion with robust thermal performance → Suitable for dense electrical rooms and cabinets in demanding environments. Compact footprint with defined dimensions → Eases installation in constrained spaces and reduces enclosure modification costs → Expedites retrofit projects and new builds alike. Documentation and procurement readiness → Access to Eaton catalogs and datasheets streamlines engineering reviews and reduces quote cycles → Improves supply-chain reliability for hazardous-location projects. Industry-ready design → Aligns with oil & gas, chemical processing, mining, and water treatment needs, delivering safer, more reliable power within hazardous-area installations.

FAQs
When installing in Hazardous Location zones, ensure the unit is housed in approved HazLoc enclosures and mounted per Class I Division 2 guidance. Verify ambient temperature ratings, use proper wiring methods, and maintain required clearances. Follow lockout/tagout procedures and confirm that wiring practices meet regional electrical codes. This approach minimizes ignition sources and protects personnel during operation, maintenance, and inspections.
This transformer provides 25 KVA at a single-phase 480-120/240 V configuration with a 115°C rise. Designers should plan for appropriate panel space, conductor sizing for 25 KVA loading, and heat dissipation in confined enclosures. The 480-120/240 ratio supports step-down distribution in control rooms and equipment enclosures, enabling stable secondary voltage for sensors, relays, and motors in hazardous-area applications.
Yes. The Z48N11S25CUSS is intended for hazardous-location applications and Class I Division 2 environments, common in oil & gas, chemical processing, mining, and similar sectors. Its encapsulated design provides protection against moisture and dust, supporting safe operation within classified zones. Confirm region-specific approvals with Eaton to match local regulatory requirements and site standards.
Official documentation is available from Eaton, including the Specification Sheet at www.eaton.com/us/en-us/skuPage.Z48N11S25CUSS.pdf and the Commercial Distribution Transformers Volume 2 catalog at www.eaton.com/content/dam/eaton/products/low-voltage-power-distribution-controls-systems/transformer/files/transformer-distribution-catalog-volume-2-tab-ca08100003e.pdf. These resources provide detailed technical data, installation guidelines, and wiring diagrams to support engineering reviews and procurement.
Procurement benefits from the included catalogs and datasheets, supporting quick specifications, quotes, and PO generation. The encapsulated design typically reduces maintenance needs in harsh environments by limiting ingress and degradation. Plan for region-specific certifications with the manufacturer, maintain a stocking strategy for spares, and coordinate with distributors to ensure timely deliveries for Hazardous Location projects.
