Eaton S20N11P16SS4X General encapsulated transformer - UL
Part Number: S20N11P16SS4X
Quick Summary
The Eaton S20N11P16SS4X is a general-purpose encapsulated transformer for reliable voltage conversion in control panels. In harsh environments, limited space, corrosion risk, and enclosure protection can stall uptime. UL Listed certification and a NEMA 4X Grade 304 stainless steel enclosure ensure rugged, compliant operation indoors or outdoors. With copper windings and a 1.5 kVA rating, it delivers stable voltage under load. The 60 Hz single-phase design matches most automation systems, easing integration and reducing installation risk. In addition, its indoor-outdoor enclosure supports versatile placement, while a compact footprint fits crowded electrical rooms. This combination translates to lower total cost of ownership and faster project delivery for industrial automation projects.

FAQs
Mounting should accommodate the 6.52 in depth, 6.1 in width, and 10.75 in height with the 45 lb weight. Use a sturdy surface or enclosure that supports NEMA 4X-rated environments, including indoor-outdoor locations. Ensure clearance for ventilation and wiring access to maintain the 60 Hz operation and thermal performance.
The transformer provides 240/480 V primary voltage and 120/240 V secondary voltage with a 1.5 kVA (1500 VA) rating. These specs suit medium-load control circuits in automation panels and equipment racks, enabling straightforward replacement without rewiring.
Yes. It features a NEMA 4X grade 304 stainless steel enclosure and is rated for indoor-outdoor use. UL Listed certification further supports installation in outdoor spaces, factories, and washdown areas while maintaining protection against corrosion and environmental exposure.
The unit is UL Listed and offered with Eaton’s standard warranty policy, providing one year from installation or eighteen months from shipment, whichever occurs first. This supports safety compliance and assurance for procurement and maintenance planning.
Choose a location that minimizes distancing wiring runs and allows airflow to prevent overheating. Leverage the 60 Hz single-phase design to align with existing automation systems, and take advantage of the indoor-outdoor enclosure to consolidate power distribution in mixed environments, reducing maintenance visits and replacement costs over time.
