Encapsulated construction with aluminum coil delivers rugged insulation and efficient heat management, reducing moisture ingress and corrosion risk while extending MTBF for critical control panels and instrumentation enclosures. This directly translates to less unplanned downtime and lower maintenance costs in manufacturing lines and automated systems. The NEMA 3R indoor-outdoor enclosure provides weather-resilient performance, enabling installation in cabinets and outdoor electrical rooms without additional protection. For panel designers, the 1 kVA rating with 240/480 V primary and 120/240 V secondary supports flexible power distribution in compact form factors, simplifying wiring schemes and accelerating commissioning. Electrostatic shielding further mitigates EMI in electrically noisy environments, helping meet regulatory and customer requirements for sensitive instrumentation. The 67P frame, 6.56 in depth, 5.53 in width, and 13.03 in height combine a small footprint with robust enclosure integrity, easing mounting in tight spaces while maintaining serviceability. UL Listed certification adds third-party safety assurance, aligning with industry procurement standards and helping streamline supplier qualification. Overall, this transformer reduces total cost of ownership by combining reliability, installation ease, and long-term performance for industrial automation, motor control, and control cabinet applications.

FAQs
For installation, note the 67P frame, 6.56 in depth, 5.53 in width, and 13.03 in height, with a weight of 32 lb. The unit features a 90A wiring connection and no taps, simplifying wiring within standard control cabinets. It is UL Listed and designed for indoor-outdoor service in NEMA 3R enclosures, making it suitable for exterior-rated panels and sheltered locations alike.
The S20N11E01P is a 1 kVA, single-phase transformer with 60 Hz frequency. Primary voltages are 240 V or 480 V, and secondary voltages are 120/240 V. This configuration supports common control circuitry and auxiliary loads in industrial panels, enabling efficient power distribution with minimal secondary wiring and straightforward integration into 240/480 V bus systems.
Yes. The transformer features an indoor-outdoor rating with a NEMA 3R enclosure and indoor-outdoor compatibility, plus electrostatic shielding for EMI control. Its rugged encapsulated design and weather-resistant housing make it appropriate for outdoor cabinets, protected enclosures, or damp indoor spaces common in manufacturing floors.
The S20N11E01P carries UL Listed certification, ensuring third-party safety verification. It also offers electrostatic shielding to reduce EMI, a temperature rise rating of 115 °C, and a robust encapsulated construction designed for reliable operation in challenging environments. These features support compliance with common industrial safety and performance standards.
The unit includes Eaton’s warranty of one year from installation or eighteen months from shipment, whichever occurs first. Maintenance requirements are minimal due to encapsulated construction and solid-state insulation, but regular visual inspections and periodic thermal checks in high-load cabinets are recommended to ensure continued reliability and to catch any environmental exposure effects early.
