Eaton Specification Sheet - S29N12S16
Selling Policy 25-000 - Distribution and Control Products and Services
Feature: General-purpose encapsulated transformer with aluminum coil and EP design delivers reliable power in compact spaces. The aluminum coil improves heat transfer and lowers weight compared with copper-wound alternatives, allowing a smaller footprint and simpler HVAC planning in crowded panels. This combination translates to faster installation, reduced cabinet size, and long-term energy efficiency for control systems in automotive, food processing, and packaging applications. Fascinatingly, this design supports modular plant layouts where space is at a premium and uptime is non-negotiable. Application: Control panels, equipment enclosures, and distributed power points across manufacturing lines where reliable step-down power is essential. Feature: NEMA 3R enclosure and indoor-outdoor suitability. Benefit: The rugged, weather-resistant construction withstands temperature swings and moisture, reducing field failures and maintenance trips. Application: Outdoor switchgear, machine control rooms, and enclosures near loading docks where dependable 60 Hz service at 208 V primary is required. This reliability is especially valuable in two- or three-shift operations. Feature: 1.5 kVA rating with 208 V to 120 V secondary. Benefit: Reduces transformer count on a line, lowers procurement and stocking costs, and simplifies wiring in control networks. Application: PLCs, relays, sensors, and actuators across assembly lines and packaging equipment. Feature: UL Listed status and 115 °C rise rating. Benefit: Improves regulatory alignment and provides headroom for continuous operation in demanding environments. Application: Plant-wide power distribution in busy manufacturing facilities where safety certification and reliable heat management matter. Feature: Compact dimensions and weight—6.52 in by 6.37 in by 13.41 in and about 42 lb—with 511H wiring and 67 frame. Benefit: Simplifies mounting and interchange in existing panels, reduces installation time, and supports standardized hardware across systems. Application: Retrofit projects or new equipment on automation lines needing consistent form factors.
