Eaton S48M11E37CULS47 Transformer - UL Listed
Part Number: S48M11E37CULS47
Quick Summary
The Eaton general purpose encapsulated transformer provides reliable power conversion for industrial control panels and equipment rooms. Engineers often struggle with noise, enclosure exposure, and voltage-tap management in demanding facilities. This unit is UL Listed and uses a rugged NEMA 3R enclosure to enable indoor-outdoor service, reducing the need for separate housings and simplifying maintenance. With a 37.5 kVA rating, 60 Hz operation, and primary 480 V to secondary 120/240 V, it integrates cleanly into power management and distribution architectures. The copper-wound design and low-sound profile support efficiency, compliance, and long-term cost reduction in industrial automation environments.

Feature Copper wound copper coil with EP design provides high efficiency and reliable voltage regulation. Business Impact The copper windings deliver lower copper loss and better heat distribution, reducing operating costs and extending service life in demanding environments. Application Use in panel boards and industrial distribution where stable 480 V to 120/240 V transitions are required. Feature NEMA 3R enclosure and encapsulated construction offer rugged protection against moisture and dust. Business Impact Enables indoor-outdoor installation with minimal additional housing, accelerating installation in utility rooms or outdoor equipment bays. Application Ideal for control cabinets, remote motor control centers, and outdoor installations subject to varying weather conditions. Feature Tap changer with 2 taps at +2.5% FCAN and 4 taps at -2.5% FCBN provides voltage regulation under load. Business Impact Improves voltage stability for sensitive loads and reduces the need for downstream regulation equipment. Application Suitable for facilities with minor voltage fluctuations or long feeder runs. Feature Low sound level at 47 dB and 60 Hz operation supports quieter environments. Business Impact Complies with noise restrictions in compact plants and near office spaces, improving worker comfort and compliance. Application Ideal for panel rooms near production lines and service corridors. Feature 37.5 kVA rating with 480 V primary and 120/240 V secondary delivers essential capacity for medium-power distribution. Business Impact Enables efficient power conversion and avoids over-sizing, reducing total installed cost. Application Appropriate for medium-duty control panels and distribution blocks in manufacturing facilities. Feature Indoor-Outdoor usability and 115 °C rise specification provide robust performance in variable ambient conditions. Business Impact Ensures reliable operation across a wide temperature range while maintaining temperature rise limits for durability. Application Suitable for semi-exposed installations and environments where ambient temperatures vary.

FAQs
This transformer uses a NEMA 3R enclosure and is designed for indoor-outdoor service, simplifying installation in both control rooms and outdoor equipment bays. Weighing approximately 897 lb with overall dimensions around 14.06 in (depth) by 28.24 in (height) by 22.42 in (width), ensure clearance for service access and proper ventilation in new or retrofit panel assemblies.
The unit provides taps at 2 positions at +2.5% FCAN and 4 positions at -2.5% FCBN, enabling fine voltage adjustment under load. This improves secondary voltage stability for critical loads and minimizes the need for downstream regulation equipment in typical panel applications running at 480 V to 120/240 V.
Yes. With a copper-wound coil, encapsulated design, and NEMA 3R enclosure, it offers robust protection against moisture and dust. The indoor-outdoor capability makes it suitable for outdoor-mounted panels or service entrances adjacent to production lines, reducing enclosure requirements and installation complexity.
The S48M11E37CULS47 carries UL Listed certification and uses a NEMA 3R enclosure for weather-resilient performance. It operates at 60 Hz with a 37.5 kVA rating, primary voltage 480 V, and secondary 120/240 V, which aligns with common industrial power distribution standards.
The unit features copper windings and encapsulated construction for durability and reduced maintenance. Warranty terms follow Eaton Selling Policy 25-000 (one year from installation or 18 months from shipment, whichever occurs first). The rugged design supports longer intervals between service when used in standard conditions.
