Selling Policy 25-000 - Distribution and Control Products and Services
Feature → Business Impact → Application: Aluminum coil and EP encapsulation improve thermal management and containment, reducing oil leakage risk and enabling compact, robust assemblies; this translates to lower maintenance and longer service life in crowded electrical rooms or outdoor enclosures. Application: Panel builders can specify a single transformer type for mixed indoor-outdoor environments, simplifying stocking and installation while maintaining reliability. Feature → NEMA 3R enclosure and indoor-outdoor rating provide weather resistance and protection against dust and moisture; Impact: up-front protection reduces field failures and service calls. Application: Outdoor substations or process plant interiors where environmental exposure is a concern. Feature → 7.5 kVA, 60 Hz, single-phase rating; Impact: supports meaningful load without oversizing, improving energy efficiency and capital utilization. Application: Control systems, motor starters, and automation logic feeding from 120/240 V sub-systems. Feature → Multiple primary voltages (120/208/240/277 V) and secondary 120/240 V; Impact: reduces the need for multiple transformers on site, cutting procurement time and installation complexity. Application: Facilities with diverse power sources or aging electrical infrastructure. Feature → UL Listed and enclosure‑level protection; Impact: accelerates compliance chat with facilities teams and provides documented safety assurance for audits. Application: Regulatory-driven projects requiring formal safety certification. Feature → 115 °C rise and 7.5 kVA rating; Impact: reliable thermal performance under full load, minimizing derating and extending service life. Application: High-demand automation loops and peak-load scenarios in manufacturing lines.

FAQs
Ensure your panel enclosure can accommodate a 9.89 in depth, 16 in height, and 10.38 in width transformer. Verify the 921A wiring connection and respect the NEMA 3R indoor-outdoor rating. Use appropriate mounting hardware, confirm clearance for cooling, and interconnect per standard control-maintenance practices.
Primary voltages are 120 V, 208 V, 240 V, and 277 V, while the secondary delivers 120/240 V. This configuration supports common industrial controls and automation gear, enabling voltage conversion from diverse mains sources to standard control voltages without additional adapters.
Yes. The unit features a NEMA 3R enclosure and an indoor-outdoor design, along with aluminum coil and epoxy encapsulation, delivering reliable performance in exposed or rugged spaces while maintaining electrical protection and thermal stability.
The transformer follows Eaton’s policy: a one-year warranty from installation or eighteen months from shipment, whichever occurs first. For service, consult the Warranty guides and Selling Policy 25-000 for scope and claim procedures, including coverage limits and replacement timelines.
With 7.5 kVA capacity, single-phase 60 Hz operation, UL Listing, and a compact, weather-resistant enclosure, this transformer reduces part count, simplifies stocking, and minimizes field maintenance. Its aluminum coil and encapsulated design enhance reliability, supporting longer intervals between service visits and lower downtime in production lines.
