Feature: General-purpose encapsulated EP design. The encapsulated construction provides robust isolation and a compact form, reducing field failure points and simplifying mounting in crowded panels. This is ideal for machine builders seeking a durable transformer with predictable performance in control panel builds. Feature: 0.15 kVA rating at 50-60 Hz with single-phase operation. This rating is sufficient for low-power control circuits, enabling efficient voltage transformation without oversizing equipment. Application: control cabinets and small automation panels. Feature: Primary voltage options 240 V and 480 V with secondary 120/240 V and no tap changer. This simplifies compatibility across equipment and reduces stocking of variant parts. Business impact: minimizes wiring errors and shorten procurement cycles. Feature: NEMA 3R enclosure for indoor-outdoor service. The enclosure supports weather resistance and IP-like protection in exposed installations, reducing the need for separate housings. Application: outdoor control panels and exposed installations. Feature: Aluminum coil, compact dimensions—4.87 in W × 4.06 in D × 8.97 in H—and 12 lb weight. The light yet sturdy construction enables easy handling during installation and space-efficient mounting. Benefit: faster retrofit and lower labor costs on site. Feature: UL Listed certification and Eaton warranty coverage. This combination promotes compliance with safety standards and provides peace of mind for maintenance planning. Application: plant asset management and service contracts.

FAQs
The S20N11S83X is a general-purpose encapsulated transformer designed for indoor-outdoor power distribution in industrial control panels. It delivers 0.15 kVA at 50/60 Hz with a single-phase input of 240/480 V and a 120/240 V secondary, making it ideal for logic circuits and compact automation panels in harsh environments.
The unit measures 4.87 inches in width, 4.06 inches in depth, and 8.97 inches in height, with an approximate weight of 12 pounds. This compact footprint supports easy retrofit and installation in space-constrained control panels and enclosures.
This transformer is UL Listed and features a NEMA 3R enclosure rating, suitable for indoor-outdoor service. The combination ensures safety compliance and weather resistance for exposed panel installations, aligning with industry standards for reliable power conversion in industrial settings.
Wiring uses a 3A connection with no tap changer (None). Primary voltage options are 240 V or 480 V, and the secondary provides 120/240 V. Installers should follow standard panel wiring practices, ensure proper clearances for air flow, and mount within the NEMA 3R enclosure to protect against environmental exposure.
UL Listing and a one-year Eaton warranty support lifecycle maintenance and compliance. The 0.15 kVA, single-phase design minimizes energy waste for small control loads, reducing operating costs while enabling consistent spare-part compatibility and lower procurement risk in plant asset management.
