Eaton S20N11P16PCU Encapsulated Transformer - 115C Rise Copper
Part Number: S20N11P16PCU
Quick Summary
The Eaton S20N11P16PCU encapsulated transformer delivers reliable low-voltage power for general-purpose control panels. In compact industrial enclosures, engineers often battle heat buildup, moisture ingress, and mounting constraints that slow commissioning and raise maintenance costs. Certifications are to be confirmed with the manufacturer; typical regional approvals include CE and UL listings where required. The unit’s encapsulated copper windings and single‑phase design support efficient operation, with 240/480 VAC input and 120/240 VAC output enabling flexible panel layouts. By delivering 1.5 kVA of power in a rugged package, this transformer helps reduce spare part stock, improve reliability, and lower lifecycle costs in automation and power-distribution installations.

Feature encapsulated construction provides moisture and dust protection, boosting reliability in harsh environments. The sealed enclosure resists humidity, thermal cycling, and contaminant ingress, reducing insulation degradation and unexpected transformer trips in outdoor or damp plant areas. This translates to fewer field calls and longer intervals between servicing for control panels in manufacturing floors, outdoors, or wash-down areas. Feature copper windings deliver low resistance and high electrical efficiency, translating to cooler operation and lower energy losses during peak loads. The improved thermal performance helps maintain stable output voltage under dynamic control sequences and heavy start-up currents typical of motors and drives. Applications include PLC power rails and auxiliary circuits in machine lines where efficiency directly affects operating costs. Feature 1PH operation with 240/480 VAC input and 120/240 VAC output provides flexible wiring options and compatibility with common industrial mains. This versatility simplifies panel design, reduces the need for additional transformers, and accelerates commissioning in multi-voltage environments. Engineers can reuse existing field wiring strategies and stock fewer parts, improving procurement efficiency. Feature 1.5 kVA rating supports simultaneous control circuits, sensors, and signaling loads without oversizing the panel. It enables more compact enclosures and less copper in parallel components, lowering upfront costs and footprint. In practice, this means faster time-to-market for equipment and lower total installed cost. Feature encapsulation and compact form factor improve mounting ruggedness and service life, while simplifying installation in tight spaces. The encapsulated transformer also helps meet moisture resistance and safety requirements across multiple regions, provided the correct approvals are in place. For maintenance, the unit’s sealed design reduces dust ingress and allows longer intervals between inspections.

FAQs
Install in a suitably rated enclosure with adequate ventilation, and mount securely to minimize vibration. Connect the 240/480 VAC primary per manufacturer wiring diagrams and ensure the 120/240 VAC secondary feeds only the intended loads. Verify routing to avoid short circuits, and follow local electrical codes during wiring and grounding.
The unit is a single-phase transformer rated at 1.5 kVA with 240/480 VAC input and 120/240 VAC output. It uses copper windings and features an 115°C rise, suitable for general purpose power distribution in industrial settings. It supports common PLCs and control circuits without requiring additional impedance calculations.
Yes, its 1.5 kVA rating and encapsulated construction make it well-suited for machine tool control panels. The copper windings deliver efficient operation, while the encapsulation protects against moisture and dust. Ensure input/output voltages match your tool's needs and that the enclosure provides adequate clearance for heat dissipation.
Certifications are to be confirmed with the manufacturer. Depending on region, regional approvals such as CE or UL listings may be required; verify with Eaton for the exact certifications applicable to your market and installation. This helps ensure compliance with electrical safety standards in your facility.
Encapsulation protects windings and insulation from moisture, dust, and humidity, reducing maintenance needs and the risk of insulation degradation. Copper windings contribute to higher efficiency and cooler operation, lowering running costs. A reliable transformer also reduces downtime in critical automation circuits, delivering a favorable return on investment over its service life.
