The S38N12S07 delivers 7.5 kVA of power at 380 V primary and 120 V secondary, enabling robust control circuits in compact panel footprints. This translates to improved reliability in machine controls and panel power distribution, reducing downtime and enabling faster startups in automation lines. The single-phase, 60 Hz design ensures compatibility with standard industrial power, while the aluminum coil and encapsulated EP construction optimize heat management and durability under typical operating conditions. The NEMA 3R enclosure and Weathershield indoor-outdoor rating provide weather resistance for workstations, service areas, and outdoor installations, lowering weather-related maintenance costs. UL Listed certification confirms safety compliance, easing procurement and commissioning for regulated environments. The wiring connection of 511P and absence of taps simplify installation, speeding up retrofit projects and minimizing field errors. A 131 lb weight is balanced for semi-permanent mounting, improving stability and reducing vibration concerns in busy panels. The guaranteed 1-year warranty (or 18 months from shipment) adds financial protection and supplier support for long-term ownership.

FAQs
Ensure mounting within a 9.89 in depth, 10.38 in width, and 16 in height footprint, with proper clearance for heat dissipation. Use the 511P wiring connection and avoid taps to simplify wiring. Verify indoor-outdoor suitability with the NEMA 3R enclosure and place in a location that minimizes moisture exposure and vibration to maximize reliability.
Yes. The transformer provides a 380 V primary and 120 V secondary, operating at 60 Hz in a single-phase configuration. This matches common industrial control architectures and panel power distribution schemes, enabling straightforward integration with PLCs, relays, and motor starters while delivering stable control power.
Absolutely. It features a NEMA 3R enclosure designed for indoor-outdoor use and is UL Listed for safety compliance. This combination supports installation in damp or outdoor-adjacent spaces, reduces environment-driven risk, and simplifies regulatory acceptance during audits and commissioning.
The unit is rated for 7.5 kVA with a 115 °C rise, suitable for continuous control power in typical industrial settings. Aluminum coil construction aids heat dissipation, helping maintain voltage stability and reducing thermal stress on connected devices. Expect reliable operation under normal loading in panel power distribution scenarios.
Eaton provides a warranty of one year from the date of installation or eighteen months from shipment, whichever occurs first, per policy 25-000. This covers manufacturing defects and provides access to Eaton support for troubleshooting, parts, and service guidance during the initial ownership period.
