Eaton S20N11P26SS4X General-purpose encapsulated transformer - NEMA 4X indoor-outdoor
Part Number: S20N11P26SS4X
Quick Summary
Eaton S20N11P26SS4X is a general-purpose encapsulated transformer delivering reliable single-phase power for industrial control. Operators frequently face weather exposure, corrosion, and unexpected downtime; this unit’s rugged enclosure mitigates those challenges while simplifying field installation. While the catalog notes a NEMA 4X enclosure with 304 stainless steel construction, key specifications such as 0.25 kVA, copper windings, and a 60 Hz rating ensure dependable performance across harsh environments. The transformer is designed for indoor-outdoor use with a 240/480 V primary and 120/240 V secondary, aligning with common automation panel requirements. In practice, this translates to streamlined procurement, predictable maintenance intervals, and safer, more compliant power distribution for control systems and peripheral equipment.

FAQs
Install the transformer in a suitable enclosure with proper clearance for cooling and service access. Mount using compliant hardware, connect the 240/480 V primary to the supply following local codes, and wire the 120/240 V secondary to the control circuits. Ensure copper windings are intact and use rated connectors to maintain voltage integrity at 60 Hz.
Primary voltage is 240 V or 480 V, secondary voltage is 120 V or 240 V, frequency 60 Hz, phase single-phase, and volt-ampere rating 0.25 kVA. Winding material is copper, and enclosure is NEMA 4X for indoor-outdoor use. Temperature rise is 115 °C, making it suitable for modest-load industrial applications.
Yes. The unit is designed for indoor-outdoor operation with a NEMA 4X enclosure and a 304 stainless steel construction note. This provides robust protection against dust, water, and corrosion, enabling reliable performance in manufacturing floors, outdoor panels, and wash-down areas.
Certification details are listed as Contact Manufacturer in the data. While the enclosure and rating support rugged use, confirm CE, UL, or SIL certifications with Eaton directly to ensure compliance for your specific region and application.
Warranty follows Eaton Selling Policy 25-000: one year from installation or eighteen months from shipment, whichever occurs first. For maintenance, inspect enclosure integrity, verify copper windings show no signs of insulation damage, and ensure mounting hardware and terminations remain secure to sustain reliable operation.
