Feature: Encapsulated aluminum coil construction. Business impact: enhances moisture resistance, reduces core losses, and improves thermal performance, extending service life in damp or dusty environments. Application: ideal for outdoor installations on walls or in equipment rooms where climate control is limited, delivering consistent voltage regulation with minimal maintenance. Feature: NEMA 3R enclosure with indoor-outdoor capability. Business impact: simplifies site planning by allowing a single transformer to serve both indoor control panels and outdoor equipment without additional protective enclosures. Application: aligns with plant-wide power-distribution strategies in manufacturing floors, warehouses, and process lines, reducing install time and total cost of ownership. Feature: 25 kVA, 60 Hz, single-phase with 120/240 V primary and 120/240 V secondary. Business impact: supports a broad spectrum of control power needs, minimizes voltage mismatch, and improves load management across machines. Application: machine tools, PLC power supplies, and lighting systems where reliable isolation and compact form factor are required. Feature: Wiring connection 3E and rugged frame 182. Business impact: eases field wiring, ensures predictable tapping and wiring layouts, and offers a stable mounting footprint for tight spaces. Application: retrofit projects in existing switchgear or new builds where compact footprint and standardized connections are critical. Feature: Weight and dimensions plus UL Listed certification. Business impact: heavy-duty build with 375 lb weight and 14.12 in depth, 16.35 in width, and 23.31 in height provides structural stability and predictable mounting, while UL Listing confirms compliance for safety and performance. Application: projects requiring safe, compliant installation in industrial environments.

FAQs
Plan for a single-phase, indoor-outdoor installation with a NEMA 3R enclosure. Ensure adequate clearance for cooling and wiring access, confirm support for the 14.12 in depth, 16.35 in width, and 23.31 in height, and prepare for a 375 lb unit that may require lifting equipment. Use the 3E wiring connection and respect manufacturer torque specs for connections.
The unit delivers 25 kVA at 60 Hz in single-phase operation. Primary voltage is 120/240 V with secondary 120/240 V. It uses an aluminum encapsulated coil, has a voltage rise of 115 °C, and is UL Listed. This makes it suitable for control panels, MCCs, and other plant loads requiring isolated, reliable power.
Yes. The transformer is designed for indoor-outdoor service with a NEMA 3R enclosure and Weathershield capable construction. It is specifically rated for environments where weather exposure or dust is a concern, enabling flexibility in placement while maintaining performance and safety.
The S10N11S25N is UL Listed, signifying compliance with safety and performance standards. This simplifies procurement and ensures alignment with many regulatory requirements for electrical equipment in industrial facilities. The NEMA 3R enclosure further supports environmental protection in both indoor and outdoor environments.
Encapsulated aluminum coil design combined with UL Listing and rugged enclosure reduces maintenance needs by resisting moisture and contaminants, lowering insulation degradation risk. The 25 kVA rating supports scalable power delivery with fewer units, which can reduce installation complexity and long-term operating costs while improving system reliability and uptime.
