Encapsulated EP design delivers a rugged, moisture-resistant housing that protects windings and minimizes contamination ingress, reducing field service calls and downtime in harsh environments. Business impact: higher equipment uptime and safer operation in outdoor enclosures or damp production areas. Application: control panels and remote motor starters where reliability is critical. Aluminum coil construction provides corrosion resistance and lightweight handling, lowering installation effort and long-term maintenance costs. Business impact: easier field mounting and fewer replacement parts, supporting cost-effective automation projects. Application: general-purpose automation transformers in industrial facilities. The NEMA 3R enclosure and indoor-outdoor weather protection enable versatile installation across shop floors and outdoor equipment housings without compromising safety or performance. Business impact: broadened deployment scenarios and simplified sourcing for mixed environments. Application: outdoor control cabinets, weather-exposed MCCs, and compact power-distribution nodes. With 1.5 kVA capacity, 480 V primary and 120 V secondary, and 60 Hz single-phase operation, it matches typical control-panel needs while preserving space. Business impact: predictable power delivery for sensors, relays, and auxiliary drives, improving system efficiency. Application: panel boards and machine interfaces requiring stable low-voltage supply. The unit weighs 43 lb and measures 6.52 in by 13.41 in by 6.37 in, offering a compact footprint that eases installation in tight spaces. Business impact: faster commissioning and reduced cabinet footprint. Application: retrofit projects and new builds where space is at a premium. UL Listed certification and Eaton’s 25-000 warranty reinforce compliance and support, reducing procurement risk and warranty administration. Application: quality-assured sourcing for regulated manufacturing environments.

FAQs
The S48N12S16 is built for rugged panel installations with a NEMA 3R enclosure, allowing indoor-outdoor use. Its 6.52 in depth and 13.41 in height fit standard electrical enclosures, and the 511C wiring connection simplifies field wiring. Ensure proper clearance for heat dissipation and follow UL Listed guidelines during mounting and wiring for safe, compliant operation.
Key specs include 1.5 kVA VA rating, 480 V primary, 120 V secondary, 60 Hz, single-phase operation, and an aluminum coil. These parameters support reliable step-down power for control circuits and sensors in industrial automation. The temperature rise is 115 °C, which informs ventilation considerations and prevents overheating in compact installations.
Yes. The S48N12S16 employs a general-purpose encapsulated design with a NEMA 3R enclosure and indoor-outdoor capability (Weathershield: Indoor-Outdoor). This makes it appropriate for outdoor panels, sheltered installations, and environments where moisture or dust exposure is a concern, while UL Listed certification provides an added layer of regulatory assurance.
The transformer is UL Listed and designed for indoor-outdoor use with a NEMA 3R enclosure. While CE and IP ratings are not specified in the provided data, UL Listing and rugged enclosure design generally support compliance in many North American industrial environments and provide a solid benchmark for regulated safety requirements.
Eaton provides a one-year warranty from installation or 18 months from shipment, whichever comes first, under policy 25-000. This coverage reduces lifecycle risk and lowers total cost of ownership by limiting early failure costs. Regular maintenance remains simple due to robust encapsulation and the straightforward wiring configuration (511C).
