Eaton S20N11S03CUSS4X Encapsulated Transformer - NEMA 4X
Part Number: S20N11S03CUSS4X
Quick Summary
Eaton S20N11S03CUSS4X encapsulated transformer provides reliable single‑phase power for control panels and industrial equipment. Many panels face harsh environments and corrosion, so a rugged, weather‑resistant enclosure helps reduce downtime. Regulatory certifications such as CE, SIL, or IP are not listed here; verify with Eaton for your region. Still, the unit uses copper windings and a NEMA 4X enclosure for durable, efficient distribution in demanding installations. In terms of business value, expect consistent voltage conversion, reduced maintenance costs, and streamlined procurement for general‑purpose transformer needs. Engineers will appreciate quick compatibility with 240/480 V primary and 120/240 V secondary loads. The 60 Hz single‑phase design suits a wide range of control panels, motors, and automation equipment.

Encapsulated construction, EP design, and a rugged NEMA 4X stainless steel enclosure deliver reliable protection against dust, moisture, and corrosion in challenging environments, reducing field failures and maintenance costs. This translates to lower total cost of ownership and fewer unplanned outages in control panels and automation racks. The unit’s copper windings, combined with a 3 kVA rating, offer efficient power transfer with robust thermal handling for continuous operation in demanding industrial settings. With primary voltages of 240 V and 480 V and secondary outputs of 120/240 V, the transformer supports a broad range of equipment—from conveyor controls to machine tools—while maintaining voltage integrity across loads. The compact 8 in depth by 14.25 in height by 7.69 in width footprint, mounted on the 1764X frame, enables straightforward installation in existing cabinets and on standard mounting rails, fostering faster project timelines and reduced installation labor. Indoor‑Outdoor Weathershield compatibility and a NEMA 4X enclosure further extend service life in both indoor plants and outdoor enclosures, minimizing exposure risks and environmental wear. A one‑year Eaton warranty (or eighteen months from shipment, whichever comes first) provides confidence in long‑term performance and supplier support, helping procurement teams justify this asset with predictable maintenance planning and ROI.

FAQs
Install the transformer within a NEMA 4X‑rated enclosure to protect copper windings and achieve environmental resistance. Use the 1764X frame as a mounting reference, ensure proper clearance for heat dissipation, and connect the 240/480 V primary to suitable power rails while routing the 120/240 V secondary to the load circuits. Validate mechanical fit using the 8 in X 14.25 in X 7.69 in dimensions and follow local electrical codes during panel wiring.
The transformer operates at 60 Hz with a single phase. It has a 3 kVA VA rating, primary voltages of 240 V and 480 V, and secondary voltage of 120/240 V. Copper windings are used for efficient conduction, and it is designed for indoor-outdoor use under a NEMA 4X enclosure with a 115 °C rise. This makes it suitable for a variety of control panels and automation equipment.
Yes. The product features a Weathershield indoor-outdoor capability and a NEMA 4X enclosure with Grade 304 stainless steel notes, which provides corrosion resistance and protection against environmental exposure. This makes it appropriate for installations that face varying temperatures, moisture, and dust, reducing the risk of enclosure compromise and extending service life.
The transformer carries Eaton’s warranty of one year from date of installation or eighteen months from shipment, whichever occurs first. This policy, referenced as Eaton Selling Policy 25-000, offers assurance on product performance and spares support. For region-specific terms, consult Eaton field support or the distributor network.
Ideal for general‑purpose power distribution in control panels, machine automation, and industrial equipment, the S20N11S03CUSS4X delivers reliable single‑phase power from 240/480 V inputs to 120/240 V outputs. Its 3 kVA rating, copper windings, and robust enclosure make it well-suited for harsh manufacturing environments and compact electrical assemblies requiring dependable voltage conversion.
