FAQs
The S25N11S07 weighs 126 lb and has overall dimensions of 9.89 in (L) x 16 in (H) x 10.38 in (W). Plan for adequate mounting clearance, vibration control, and access for wiring connections (26D). Its NEMA 3R enclosure supports outdoor use, reducing additional enclosure costs and weatherproofing steps during installation.
This unit is a single-phase transformer with a 220 V primary and 120/240 V secondary, rated at 7.5 kVA, operating at 60 Hz. Wiring connection is 26D, and the design uses aluminum coil windings to balance performance and weight in typical industrial distribution applications.
Yes. Its EP encapsulation, aluminum windings, and NEMA 3R indoor-outdoor enclosure are specifically chosen to withstand dust, moisture, and outdoor exposure. These features simplify installation in outdoor control rooms or exposed wall panels while maintaining regulatory compliance and reliable performance.
The transformer carries UL Listed certification, confirming electrical safety compliance for industrial applications. This certification helps streamline procurement and reduces internal verification requirements. While CE or IP ratings are not listed in the data, the NEMA 3R enclosure provides practical weather resistance for outdoor installations in many regions.
Eaton provides a one-year warranty from installation or 18 months from shipment, whichever comes first. With a rugged encapsulated design, aluminum windings, and UL approval, expected ROI includes reduced maintenance, longer service life, fewer unplanned outages, and lower lifecycle costs for critical power distribution in industrial environments.
