FAQs
The S20K11S10S64X is a single-phase transformer rated for 240 V or 480 V primary and 120/240 V secondary, designed for general-purpose encapsulated use. It features a FR1794X frame and aluminum windings, making it straightforward to mount in standard control panels or distribution enclosures. With a NEMA 4X / indoor-outdoor enclosure, it suits rugged installations without special mounting adapters. Tap settings at -10% and -5% FCBN support minor voltage compensation on-site, helping maintain target voltages in typical industrial environments.
Key specs include a 10 kVA VA rating, 60 Hz frequency, single-phase operation, primary voltages of 240 V or 480 V, and secondary voltages of 120/240 V. The enclosure is NEMA 4X with 316 stainless steel, suitable for indoor-outdoor service. The device uses aluminum windings and supports voltage taps at -10% and -5% FCBN, with a temperature rise rated at 150 °C. These features collectively enable reliable control-panel power distribution in demanding environments.
Yes. The S20K11S10S64X is built for indoor-outdoor use with a NEMA 4X, 316 stainless steel enclosure, ensuring corrosion resistance and weather sealing. Its Weathershield rating confirms suitability for harsh environments, while the rugged FR1794X frame supports stable operation in outdoor cabinets or wash-down areas. Proper installation and enclosure sealing are still recommended to maximize durability in extreme conditions.
Certifications field lists Contact Manufacturer, but the enclosure carries a NEMA 4X rating with 316 stainless steel construction, underscoring environmental protection for indoor-outdoor service. For broader regulatory compliance (UL/CE), verify with Eaton or your distributor prior to procurement, as device-specific certificates may vary by region and batch. The product’s data sheet provides installation guidance aligned with common industrial practice.
Expected maintenance is minimal due to the rugged encapsulated design, stainless enclosure, and aluminum windings, which resist corrosion and heat. The 10 kVA rating supports efficient power delivery for control circuits, reducing downtime and voltage-related faults. Over the lifecycle, the enclosure’s durability lowers replacement frequency, while the voltage-tap capability helps maintain performance with fluctuating supply, contributing to a favorable return on investment.
