7.5 kVA rating, 480 V primary, 120/240 V secondary, single-phase operation, and 60 Hz frequency deliver robust power for demanding automation loads, reducing the need for multiple smaller transformers and simplifying the panel design. Business impact: consolidated power conversion and improved panel density; application: machine control cabinets and process automation panels allow faster commissioning and easier maintenance. Aluminum coil construction lowers weight and improves heat dissipation, enhancing reliability in confined spaces. Business impact: longer service life and reduced cooling requirements; application: indoor-outdoor installations where airflow may be limited and ambient temperatures vary. The EP design with NEMA 3R enclosure provides weather resistance and ruggedness, reducing risk of weather-related outages. Business impact: lower downtime and improved uptime in outdoor or semi-covered installations; application: outdoor equipment bays and harsh environments. Tap changers—2 at +2.5% FCAN and 2 at -2.5% FCBN—enable precise voltage regulation under load, improving device performance across dynamic conditions. Business impact: tighter voltage control; application: sensitive electronics and motor-driven loads. The 16 A wiring connection supports straightforward field wiring, while the 115 °C rise rating ensures tolerance for short-term overloads. Business impact: flexible installation and resilience in peak demand periods; application: distributed power for control systems and lighting in industrial facilities.

FAQs
For straightforward installation, mount the unit in a suitable enclosure that accommodates its 9.89 in depth, 16 in height, and 10.38 in width. Use a 16A wiring connection and respect the NEMA 3R indoor-outdoor rating to ensure weather resistance. The two +2.5% and two -2.5% taps help maintain voltage under varying load and supply conditions.
The transformer is single-phase, rated at 7.5 kVA, with a 480 V primary and 120/240 V secondary. It operates at 60 Hz and uses an aluminum coil. Tap settings include 2 at +2.5% FCAN and 2 at -2.5% FCBN, providing voltage regulation to support sensitive equipment.
Yes. The unit features a NEMA 3R enclosure and an indoor-outdoor Weathershield designation, enabling reliable operation in exposed or semi-exposed locations. This reduces enclosure changes and provides durable service for outdoor panels and remote installations.
The transformer is UL Listed, ensuring compliance with safety standards for electrical equipment. Eaton provides a warranty policy of one year from installation or eighteen months from shipment, whichever occurs first, offering protection against manufacturing defects during initial use.
With a 7.5 kVA rating, aluminum coil, and precise voltage taps, it delivers reliable power with minimized losses and improved voltage regulation. Fewer transformers are needed in a panel, reducing installation time and inventory, while rugged construction and weather resistance cut maintenance costs and downtime in industrial environments.
