Copper windings in the EP-design S10N11S15CU deliver superior conductivity and heat management, translating into lower copper losses and steadier voltage regulation. The robust construction supports longer service life in demanding environments, reducing maintenance costs over the life of the installation. In panel builds with limited space, the 180-frame size and encapsulated enclosure maximize accessibility while preserving thermal performance.\n\nNEMA 3R enclosure provides rugged indoor-outdoor protection, shielding windings from moisture, dust, and temperature swings. This means outdoor installations can be deployed without additional weatherproof housings, simplifying wiring runs and accelerating commissioning. Operators gain reliability in variable climates and lower maintenance costs in distributed power panels.\n\nDual-voltage primary and secondary (120/240 V) support flexible designs and easier stock management, letting technicians match equipment without extra transformers. The 60 Hz, single-phase rating and 15 kVA capacity align with common control panels and motor loads, reducing the need for undersized or oversized solutions. The 3E wiring option also simplifies field connections and reduces miswiring risk.\n\nThermal performance is robust, with a 115 °C rise that accommodates short-term overloads without compromising voltage stability or insulation integrity. This capability improves responsiveness in peak load conditions and helps maintain product performance in mixed-duty environments.\n\nUL Listed certification demonstrates compliance with recognized safety standards, while the one-year warranty (or 18 months from shipment) provides business protection and predictable maintenance planning. Together, these factors lower lifecycle risk and support a quick ROI for new installations and panel retrofits.\n\nPractical installation advantages include a manageable 232 lb weight and a compact footprint: 10.52 in depth, 19 in height, and 13.38 in width. The unit’s 180-frame design and copper coil allow straightforward mounting, cabling, and service access in typical industrial rack and enclosure assemblies.

FAQs
For reliable deployment, plan mounting on a rigid surface that supports the 232 lb unit weight, and ensure adequate ventilation within the enclosure. Wire using the 3E connection scheme, keep primary and secondary conductors properly sized for 120/240 V service, and respect the NEMA 3R enclosure rating for outdoor or wash-down environments. Verify fit within a 180-frame footprint and provide clearance for service access.
The transformer operates at 60 Hz single-phase with a 15 kVA rating. It has a primary voltage of 120/240 V and a secondary voltage of 120/240 V, with copper windings for high efficiency. The enclosure is NEMA 3R rated, designed for indoor-outdoor service, and the unit supports 3E wiring for straightforward field connections. Temperature rise is rated at 115 °C.
Yes. Its general-purpose encapsulated design, copper windings, 15 kVA rating, and 120/240 V primary-to-secondary configuration align with typical control-panel loads. The NEMA 3R enclosure, UL Listed safety, and compact 180 frame help maximize panel density while maintaining reliability in demanding factory environments and automated lines.
The S10N11S15CU is UL Listed, indicating compliance with recognized safety standards. It carries Eaton’s warranty policy of one year from installation or eighteen months from shipment, whichever occurs first. These assurances reduce risk, simplify procurement, and support maintenance planning for ongoing uptime in production facilities.
Copper windings improve efficiency and voltage regulation, lowering operating losses. The rugged NEMA 3R enclosure enables outdoor installations without extra housing, reducing installation time and materials. The dual-voltage design simplifies stock and panel wiring, while the UL Listing and warranty provide risk mitigation, contributing to a shorter payback period and lower lifecycle costs.
