Encapsulated transformer
Encapsulated construction provides rugged protection against dust, moisture, and incidental shorts, improving safety and reducing maintenance costs in harsh factory environments. The 37.5 kVA rating with a 240 V primary and 120/240 V secondary delivers reliable power for machine controls, automation cabinets, and panel boards, enabling smoother startup sequences and better load handling. Single‑phase encapsulated transformers simplify integration with existing control wiring, while the compact enclosure minimizes panel footprint and accelerates installation in space‑constrained panels. Thermal performance is evidenced by a 115°C rise rating, offering ample margin during peak loads and ensuring consistent operation under demanding conditions. Documentation from Eaton, including catalogs and datasheets, supports easier sizing, compliance checks, and field replacement, reducing downtime and improving total cost of ownership in manufacturing environments. This transformer is well suited for retrofit projects and new installations where standard control architectures require dependable, scalable power sources.

FAQs
Begin with a suitable enclosure, ensuring adequate clearance for heat dissipation. Verify input rating at 240 V and confirm the 120/240 V secondary outputs for your loads. Mount the encapsulated transformer using recommended hardware, connect primary and secondary circuits following the schematics in the Eaton datasheet, and ensure proper grounding. This single‑phase unit is designed to integrate with typical automation cabinets, reducing wiring complexity and enabling faster commissioning.
The 37.5 kVA rating indicates the maximum apparent power the transformer can deliver to connected loads without overheating. The 115°C rise rating provides a thermal margin that accommodates short‑term overloads and peak inrush on startup while maintaining safe operating temperatures. In practice, this supports stable performance for motor controls, programmable logic controllers, and other automation devices within a single‑phase power distribution scheme.
Yes. The S20L11S37CUS6 is designed for general purpose encapsulated transformer use in industrial automation and control panels. Its encapsulated construction offers rugged protection in dusty or humid environments, while the 240 V to 120/240 V secondary outputs align with common control and sensor circuits. It also supports straightforward integration with standard control architectures, enabling reliable power for PLCs, relays, and drive electronics.
Certifications for this specific unit should be confirmed with the manufacturer. In practice, engineers verify CE, UL, and any industry‑specific approvals as required by the installation site. Always reference Eaton’s official datasheets and the catalog with the model number S20L11S37CUS6 to confirm applicable certifications and ensure compliant integration within your regulatory framework.
Encapsulated transformers like the S20L11S37CUS6 typically offer reduced maintenance due to sealed construction that minimizes dust intrusion and moisture exposure.
