Selling Policy 25-000 - Distribution and Control Products and Services
Copper windings with EP encapsulation deliver high efficiency and robust isolation. This reduces energy losses and thermal stress, translating to lower operating costs and longer service life for automation panels. It is well-suited for factory automation and control cabinets needing a dependable 10 kVA supply from 208 V to 120/240 V at 60 Hz. Encapsulated design and a NEMA 3R enclosure provide enhanced moisture and dust protection, enabling indoor-outdoor installation and reducing the need for additional weatherproofing in exposed environments. The unit’s low sound rating of 47 dB supports quieter operation in open floor plans and near office zones, reducing the requirement for separate sound enclosures. The 10 kVA capacity with copper windings, fixed 208 V primary, and 120/240 V secondary simplify procurement and improve load planning for machine centers and process lines. Built-in UL Listing and Eaton warranty support regulatory compliance and predictable maintenance planning, minimizing downtime and risk.

FAQs
The transformer is a single-phase 60 Hz device with a 208 V primary and 120/240 V secondary, rated at 10 kVA. Mount it in a suitable enclosure or panel, ensure proper clearance, and connect the 208 V line to the primary using 26A-rated wiring. Terminate the 120/240 V outputs to the associated panel loads, and verify tight connections per local electrical codes.
At full 10 kVA, the transformer can deliver about 83 A at 120 V or 41.7 A at 240 V, depending on load distribution and efficiency. It provides fixed voltage ratios (208 V to 120/240 V) for reliable control power. For best results, balance loads across the secondary and monitor temperature rise to avoid overheating.
Yes. The unit features a NEMA 3R enclosure designed for indoor-outdoor use and is specified as indoor-outdoor capable. Its weather-resistant encapsulation, combined with the Weathershield designation, supports reliable operation in exterior-rated spaces such as equipment rooms adjacent to outdoor installations or exposed manufacturing areas.
The S29N11S10CULS47 is UL Listed, confirming safety and performance compliance. It uses a rugged encapsulated EP design for reliability in industrial environments and supports standard power-distribution practices in factories. This certification aids in regulatory approvals and simplifies procurement within regulated manufacturing and distribution settings.
Warranty terms follow Eaton Selling Policy 25-000: one year from the date of installation or eighteen months from shipment, whichever occurs first. Maintenance is minimal but should include periodic insulation and thermal inspections, vent cleaning, and verifying terminations. The copper windings and encapsulated design contribute to long life and reduced maintenance frequency, supporting lower total cost of ownership.
