Eaton S27N11S51A Encapsulated Transformer - UL Listed

0.5 kVA power rating makes the S27N11S51A ideal for small to mid-size control circuits while maintaining a compact footprint. This translates to reduced panel depth and simpler wiring, cutting installation time and space costs in new builds or retrofits. Applications include control panels for automation equipment and small machines in manufacturing and facilities management. 277 V primary and 120/240 V secondary enable direct integration with standard building power distributions. The transformer supports 60 Hz single-phase operation, ensuring compatibility with common industrial controls and relays. This combination provides predictable voltage conversion and reliable start-up for PLCs, relays, and sensors, reducing field troubleshooting and downtime. NEMA 3R enclosure design delivers indoor-outdoor capability, protecting wind-driven rain, dust, and incidental impacts. Aluminum coil construction offers corrosion resistance and improved heat dissipation, enhancing long-term reliability in demanding environments. Together, these features simplify outdoor installations, minimize enclosure modifications, and extend service life in weather-exposed applications. 115 °C rise and the 58A frame contribute to a robust performance envelope for typical control-panel loads, while the 0.5 kVA rating remains within the transformer’s efficient operating window. This supports energy-conscious operation and stable voltage under peak demands, helping facilities meet uptime targets and regulatory expectations. UL Listed certification reinforces safety and compliance across electrical assemblies, while the 524A wiring connection designation clarifies installation wiring guidance and reduces miswiring risk. These attributes collectively lower lifecycle costs by reducing maintenance needs and accelerating commissioning in industrial and commercial environments.
