Eaton S29N11S03N General-Purpose Transformer - UL Listed
Part Number: S29N11S03N
Quick Summary
General-Purpose Transformer delivers reliable control power for 208 V to 120/240 V loads in commercial and industrial panels. Facilities often struggle with indoor-outdoor durability, mounting flexibility, and maintaining voltage under changing loads. UL Listed safety certification and a NEMA 3R enclosure keep equipment compliant and protected in varied environments. Designed for reliability in industrial control power, it supports efficient installation and reduces total cost of ownership. So it's a 3 kVA, 60 Hz, single-phase unit capable of stepping 208V down to 120/240V for control circuits. The aluminum coil and encapsulated design deliver reduced noise, improved heat management, and long service life. With 115 °C rise and indoor-outdoor suitability, the unit supports versatile installation across facilities.

Indoor-Outdoor
Feature: Rugged encapsulated design with a NEMA 3R enclosure provides robust protection for internal windings and connections against dust, moisture, and temperature swings. Business Impact: This reliability translates to fewer field failures, lower maintenance costs, and longer service life in both indoor and outdoor settings. Application: Ideal for outdoor panels, loading-dock installations, and industrial sites where environmental exposure is a common operating condition. Feature: 3 kVA, 60 Hz, single-phase transformer with 208 V primary and 120/240 V secondary delivers versatile control power. Business Impact: It supports reliable operation of relays, PLCs, sensors, and other control loads, reducing voltage mismatch and nuisance trips. Application: Commonly used in automation panels, motor control centers, and process skids across manufacturing facilities. Feature: Aluminum winding and encapsulated construction offer durability, corrosion resistance, and efficient heat management. Business Impact: Aluminum construction reduces weight and when paired with encapsulation helps maintain performance in humid or washdown environments, lowering installation and maintenance costs. Application: Well-suited for facilities with moisture exposure, coastal atmospheres, or washdown areas where durability matters. Feature: UL Listed safety certification and NEMA 3R-rated enclosure provide regulatory compliance and safe operation. Business Impact: Compliance simplifies procurement, supports audit readiness, and minimizes risk of safety incidents. Application: Critical for panel builds in regulated industries and applications requiring traceable safety certifications. Feature: Compact footprint with defined dimensions and wiring capacity (8 in length, 7.69 in width, 14.25 in height, 26 A wiring connection). Business Impact: Small form factor enables easier retrofit into existing panels and faster install timelines, improving project throughput. Application: Retrofit projects, space-constrained control panels, and new installations in industrial environments.

FAQs
Plan for the transformer’s 8 in length, 7.69 in width, and 14.25 in height, and its 67 lb weight. Provide a 208 V supply to the primary and distribute 120/240 V on the secondary, observing the 26 A wiring capacity. Mount in a space that complies with indoor-outdoor use (NEMA 3R) and ensure UL labeling remains visible for compliance.
The 3 kVA rating supports a range of control loads, including relays, PLCs, and sensors, by delivering stable voltage transformation from 208 V to 120/240 V at 60 Hz. This reduces voltage mismatches, minimizes nuisance trips, and improves overall panel reliability and uptime in manufacturing and processing environments.
Yes. The transformer features a NEMA 3R enclosure and an indoor-outdoor design, paired with UL safety certification. These attributes enable reliable operation in outdoor or semi-exposed spaces, while the aluminum winding and encapsulated construction further enhance durability against humidity and environmental exposure.
The primary certifications include UL Listed safety certification and a NEMA 3R-rated enclosure. These features support regulatory compliance and safe operation for panel builds used in regulated industries, with the enclosure protecting against dust and moisture and the UL listing providing traceable safety specifications for audits.
Expect low maintenance due to a robust encapsulated design and corrosion-resistant aluminum windings, which contribute to longer service life and fewer field repairs. The 1-year Eaton warranty (or 18 months from shipment) adds protection for initial deployment. The compact size and reliability translate to faster installations and reduced total cost of ownership over time.
