Encapsulated construction with an aluminum coil delivers rugged reliability in a compact footprint. The EP design protects windings and minimizes moisture ingress, reducing maintenance and extending service life in demanding control panels. This combination translates to lower total cost of ownership for industrial power distribution and automation applications. Weather-ready enclosure: The NEMA 3R housing supports indoor-outdoor installations, helping you deploy transformers in outdoor equipment racks or sheltered spaces without adding separate enclosures. This reduces installation time and cabinet count, improving space efficiency in machinery and building automation projects. Voltage compatibility and power capacity: With a 2 kVA rating at 60 Hz and single-phase operation, the S27N11S02A handles common control circuits and lighting feeds. Primary 277 V and secondary 120/240 V match typical building or process power architectures, simplifying wiring and reducing cross-connects for OEM integrations. Rigorous standards and installation ease: UL Listed certification supports compliance programs, while a 176 frame, 14.25 in height, 8 in length, and 7.69 in width fit standard racks and panels. The aluminum coil and 115 °C rise offer a good balance of efficiency and thermal performance, enabling reliable continuous operation in varied environments. Support and lifecycle: The unit carries a one-year Eaton warranty and is backed by OEM documentation including a dedicated spec sheet and catalogs. Its 524A wiring, 67 lb weight, and Model A catalog notes streamline procurement, stocking, and field service for industrial automation projects.
