Encapsulated copper-windings EP design provides rugged insulation and EMI shielding. This configuration improves reliability in harsh factory environments and reduces field failures, translating to lower maintenance and replacement costs. It is well suited for crowded control cabinets in manufacturing lines where heat, dust, and vibration are common. Low sound 42 dB and a compact footprint reduce noise and space requirements. The business impact is quieter operation and easier permitting in regulated facilities, enabling installation closer to work cells. It fits in tight spaces around equipment where sound budgets matter, while still delivering full 5 kVA capacity. Indoor-outdoor capability with NEMA 3R enclosure enables year-round operation in varied environments. This translates to reduced enclosure costs and fewer handling steps during installation, speeding up commissioning. Applications include outdoor control panels and shelter-exposed industrial cabinets. Primary 277 V and secondary 120/240 V configuration supports diverse downstream loads. The business impact is flexible power distribution to single-phase equipment and controls, enabling a single transformer to serve multiple circuits and reducing inventory. Industries such as packaging, HVAC, and lighting systems benefit from this versatility. 513B wiring and copper coil construction support easy, reliable connections. The business benefit is straightforward installation and durable performance, with low energy losses and predictable regulation under load. This is particularly valuable in retrofit projects where minimal downtime is critical. 5 kVA rating at 60 Hz supports typical control panel loads and machine tool applications. The business impact is consistent performance and reduced need for oversizing, leading to cost savings and improved efficiency in power distribution networks.

FAQs

The S27N11E05CULS42 general transformer excels in industrial control panels, machine rooms, and outdoor enclosures where reliable, single-phase power is required. Its 5 kVA rating supports multiple loads, and the 277 V primary with 120/240 V secondary simplifies wiring schemes. Its encapsulated EP design protects windings from dust, moisture, and vibration, extending service life in demanding environments.
Key specs include 60 Hz operation, single-phase design, primary voltage of 277 V, secondary voltage of 120/240 V, a 5 kVA VA rating, 115 °C rise, copper windings, and 513B wiring. These specifications enable flexible distribution to downstream control devices while maintaining safe operating temperatures under load.
Yes. The unit features a NEMA 3R enclosure and indoor-outdoor capability, allowing installation in exposed locations with protection from weather and moisture. This eliminates the need for separate weatherproof cabinets in many installations while maintaining UL Listed safety compliance.
Eaton provides a warranty under policy 25-000: one year from installation or eighteen months from shipment, whichever occurs first. The product is UL Listed, and Eaton offers standard support and documentation, including specification sheets and catalog references to facilitate procurement and commissioning.
Plan for a 140 lb unit with dimensions around 9.89 in (L) x 10.38 in (W) x 16 in (H). The 513B wiring accommodates standard panel connections, and mounting should consider accessibility for maintenance and venting. Use the included catalogs and datasheets for exact clearance, wiring routes, and upgrade options.
