Eaton Cutler-Hammer S20N11P51P Transformer
The Eaton Cutler-Hammer S20N11P51P represents a robust industrial-grade single-phase encapsulated transformer designed for demanding HVACR and electrical distribution environments. Engineered as a 0.50 kVA general purpose transformer, this NEMA 3R rated unit features a dual-voltage primary of 240/480V and a secondary output of 120/240V, making it a versatile choice for stepping down line voltage to drive control circuits or auxiliary loads. The encapsulated design utilizes a high-quality resin compound to seal the core and coil from moisture, dust, and corrosive airborne contaminants, ensuring reliable performance in harsh mechanical rooms. With its Type EP configuration, the S20N11P51P facilitates easy installation with internal wiring leads and a compact footprint. For contractors managing industrial power distribution, this transformer provides the voltage regulation and thermal stability required for long-term operational integrity without the risk of coil degradation in non-conditioned spaces.
- Environmental Protection: The NEMA 3R enclosure and encapsulation protect against weather and debris, suitable for indoor and outdoor mounting.
- Flexible Input/Output: Primary 240/480V and secondary 120/240V ratings allow for wide-ranging application across different job sites.
- Efficient Heat Dissipation: The 115°C temperature rise rating ensures stable performance under continuous load conditions.
- Reliable Construction: Aluminum windings provide a cost-effective and lightweight solution while maintaining high conductivity and step-down efficiency.
Common Questions
