Eaton S26N11S10 General-Purpose Transformer - UL Listed

General design and construction: The EP encapsulated enclosure with aluminum windings protects against moisture and corrosion, delivering long service life in harsh indoor-outdoor plant environments. This configuration reduces maintenance costs and field failures, particularly for outdoor control panels, building relays, and rugged automation cabinets that operate under severe weather, vibration, and transient power conditions. By combining a robust sealing system, efficient heat dissipation, and a flexible mounting footprint, it supports dependable operation in evolving facilities and streamlines retrofit projects for aging infrastructure. Electrical ratings and efficiency: The unit operates at 60 Hz with a 270 V primary and 120/240 V secondary, rated at 10 kVA, providing ample headroom for multiple circuits and serving as a reliable power source for PLCs, relays, and low-voltage controls. This arrangement delivers stable control voltages, minimizes feeder voltage drop, and improves PLC reliability in automation cabinets and distributed control ecosystems across manufacturing lines. In practice, the 10 kVA rating enables a single transformer to serve several relays and sensors, reducing wiring complexity, panel space, and overall capital cost while improving fault tolerance. Wiring and installation specifics: Wiring connection uses 524Y, with a frame designation of 179, enabling straightforward mounting and routing in mid-size control enclosures and serviceable access for future upgrades. The transformer is designed for indoor-outdoor use under the NEMA 3R enclosure, simplifying installation in exposed locations without extra weatherproof housings and enabling safer operation in damp or dusty environments. Compatibility with common Eaton power distribution components accelerates commissioning, lowers install risk, and ensures consistent performance across panels that share a standard 524Y wiring scheme. Safety and compliance: UL Listed certification verifies compliance with electrical safety standards for regulated facilities, while the enclosure protects sensitive windings from moisture, dust, and incidental contact in harsh environments. The device carries a 115 °C rise specification that informs thermal management planning and cooling strategies in crowded electrical rooms and high-duty cycles. Weathershield compatibility and aluminum windings further improve reliability during temperature and humidity swings typical of industrial environments and extended duty operation. Practical deployment insights: Designed to integrate with Eaton's broader power management and distribution ecosystem, the S26N11S10 supports modular expansion and reduces the transformer count needed in larger facilities, improving maintenance scheduling and spare-part inventory. Field feedback highlights quicker commissioning, steadier control voltage, and fewer field interventions compared with loose-core or multi-transformer setups, which translates to lower downtime and higher plant throughput. This general-purpose encapsulated transformer thus aligns with typical ROI expectations for panel upgrades, automation line expansions, and new equipment that require dependable, versatile power conditioning.
