Selling Policy 25-000 - Distribution and Control Products and Services
Encapsulated EP design provides moisture and dust resistance, reducing insulation degradation and extending service life in harsh environments, which translates to lower maintenance costs and fewer field failures. Business impact: improved uptime and lower total cost of ownership; Application: equipment rooms and outdoor cabinets where environmental exposure is a concern. NEMA 3R enclosure supports indoor-outdoor reliability, enabling reliable operation in varied plant climates and weather conditions. Business impact: fewer enclosure-related failures; Application: outdoor control panels and sheltered outdoor installations. The 10 kVA, single-phase 60 Hz rating with primary 240/480 V and secondary 110/220 V meets common factory loads, enabling straightforward integration with existing power distributions and control circuits. Business impact: reduced wiring complexity and faster panel upgrades; Application: step-down power routing for PLCs, drives, and motors. Aluminum coil improves corrosion resistance and thermal performance, lowering maintenance needs and long-term operating costs. Business impact: durable operation in demanding environments; Application: new installations and retrofits in manufacturing lines. A 3-meter wiring lead length simplifies field connections, reducing labor and risk of loose terminations during installation. Business impact: faster commissioning and fewer rework incidents; Application: plug-and-play integration in retrofits and OEM assemblies. The 115°C temperature rise capability supports under-load performance and stable voltage delivery, contributing to consistent equipment performance and reduced risk of undervoltage or unexpected shutdowns. Business impact: reliable process control; Application: high-load control panels and distribution boards. UL Listed certification assures safety and compliance, while indoor-outdoor suitability (Weathershield) provides versatile deployment. Frame 179 and a 197 lb weight indicate a rugged, vibration-resistant unit capable of withstanding demanding industrial environments. Business impact: meets regulatory expectations and installation in challenging spaces; Application: certified panel integration and OEM equipment.

FAQs
Mounting the S20N14S10 requires accounting for its 19 in height, 13.38 in width, and 10.52 in depth, plus a 197 lb weight. Provide adequate clearance for ventilation, secure enclosure mounting, and 3-meter wiring accessibility. Use a stable base and appropriate fasteners, and plan for field wiring length to the 110/220 V secondary circuits while ensuring UL Listed wiring practices are followed.
The transformer operates single-phase at 60 Hz with a 10 kVA VA rating. Primary voltages are 240 V or 480 V, secondary voltages are 110 V or 220 V, and it features a 115 °C rise. These specs support efficient step-down for automation panels, enabling robust performance under load with predictable voltage delivery for PLCs and control devices.
Yes. It uses a NEMA 3R enclosure designed for indoor-outdoor service and is UL Listed for safety and reliability. The aluminum coil and encapsulated EP construction further enhance durability against moisture, dust, and temperature variations, making it appropriate for exposed or partially sheltered locations in industrial settings.
The unit adheres to Eaton’s policy with a one-year warranty from installation or an eighteen-month window from shipment, whichever comes first. For maintenance, monitor insulation and enclosure integrity periodically, verify 3-meter lead connections, and confirm UL-listed wiring complies with your panel standards to minimize downtime and extend service life.
Typical applications include supplying control panels, drives, and automation equipment that require 240/480 V to 110/220 V step-down. ROI benefits come from reduced downtime due to rugged construction, faster installation with 3-meter leads, and a compact, reliable design that lowers spare-part and maintenance costs over the equipment lifecycle.
