Encapsulated transformer
Encapsulated design protects windings from moisture and dust, reducing maintenance and extending service life. This translates to fewer field failures and lower service costs for panel builders and machine integrators. The 3 kVA single‑phase rating supports control circuits, PLCs, relays, and small drives, enabling reliable operation in compact panels with reduced footprint. Copper windings deliver lower resistance, improving efficiency and heat management, which minimizes energy losses and extends component life in high‑density installations. The 277-120/240V secondary matches common automation equipment, simplifying wiring, reducing installation time, and lowering the risk of miswiring in control circuits. A rugged, encapsulated package provides a straightforward installation path in new builds or retrofits, delivering predictable performance and improved warranty coverage.

FAQs
The S27N11S03CUSS4X is a single‑phase 3 kVA transformer with a 277-120/240V secondary, designed to supply control circuits in industrial panels. It pairs well with PLCs, relays, and small motor controllers, offering stable voltages and quick wiring integration while minimizing footprint in compact control enclosures.
Encapsulation protects windings from moisture, dust, and vibration, reducing field failures and extending service life. This simplifies maintenance planning, lowers the likelihood of corrosion-related faults, and allows for more resilient operation in harsh environments. Installation remains straightforward due to a rigid, sealed package that resists contamination during panel assembly.
Best applications include control panels for machines, process automation cabinets, and distribution panels needing reliable 277-120/240V power for PLCs, relays, and small drives. Its 3 kVA rating supports moderate load requirements, while copper windings and robust heat tolerance help maintain performance during peak switching and in densely packed enclosures.
Check regionally relevant safety and compliance marks such as CE and UL when purchasing transformers for controlled environments. Certification details for this exact Eaton model should be confirmed with the manufacturer or authorized distributors to ensure alignment with local electrical codes and installation requirements.
ROI benefits come from reduced maintenance, longer service life due to encapsulation, and lower installation costs from a compact, readily wired package. The copper windings improve efficiency and heat management, contributing to energy savings and fewer field outages, which together shorten payback time in control-panel projects.
