Encapsulated construction in a NEMA 3R enclosure provides robust moisture and dust protection, enabling reliable operation in harsh environments and reducing field failures; this translates to lower maintenance costs and less unplanned downtime in panel assemblies. The no-taps primary and 400/480 V input with a 120/240 V secondary deliver clean, predictable voltage to relays and instrumentation, simplifying wiring and improving startup reliability. With a 5 VA rating and 50-60 Hz compatibility, it delivers essential control power without over-consuming energy or requiring oversized power sources, supporting compact, energy-efficient automation cabinets. The 115 °C rise rating ensures tolerance to moderate thermal loads, while the single-phase design keeps installation straightforward and cost-effective in small to mid-size control panels. Compliance with UL Listed, CSA Certified, and CE Marked standards further reduces regulatory risk across regions and accelerates procurement.

FAQs
The S51N11S05XCE is a single-phase encapsulated transformer designed for 400/480 V input and 120/240 V output with a NEMA 3R enclosure. Plan for proper panel clearance, secure mounting, and compliant wiring practices. As there are no taps, select the correct input voltage to avoid miswiring. Ensure the site supply is within 50-60 Hz to maintain performance and reliability.
This model carries UL Listed, CSA Certified, and CE Marked certifications. UL Listed confirms electrical safety for North American installations, CSA Certified supports Canadian requirements, and CE Marked demonstrates conformity with European safety and EMC standards. Together they reduce procurement risk, ease cross-border deployments, and aid during audits and customer inspections.
Yes. The transformer uses a NEMA 3R enclosure, providing protection against moisture, dust, and some weather exposure. Its encapsulated construction further enhances resistance to humidity and contaminants, making it appropriate for damp or exposed control panels in industrial facilities while maintaining reliable operation at typical environmental temperatures.
Typical use cases include powering small relays, PLC input modules, and indicator circuits within control panels and automation cabinets. With 400/480 V primary and 120/240 V secondary, it supports field devices that require low-voltage control power, enabling compact, dependable power distribution in conveyors, robotics stations, and machine enclosures while minimizing energy waste.
Eaton provides a warranty per policy 25-000: one year from the date of installation or eighteen months from shipment, whichever occurs first.
