Feature → Business Impact → Application: 3 kVA, 60 Hz, single-phase design supports standard automation loads with stable voltage regulation, enabling reliable operation of control circuits and sensors in manufacturing lines. This translates to reduced downtime and consistent performance in machine controls and distributed I/O, especially where 208 V feeds common automation equipment is present. Feature → Business Impact → Application: NEMA 3R enclosure and indoor-outdoor capability provide weather resistance and moisture protection, allowing installations in vending areas, outdoor panels, and equipment rooms without enclosure compromises or extra housings. This reduces site engineering time and protects critical electronics from corrosion and environmental ingress. Feature → Business Impact → Application: Aluminum coil and EP design deliver reduced weight and excellent corrosion resistance, cutting shipping costs and easing field handling while maintaining long-term reliability in harsh environments. This also supports easier retrofits in existing control panels that previously relied on heavier copper windings. Feature → Business Impact → Application: 77B wiring compatibility and compact footprint (8 in L x 14.25 in H x 7.69 in W) enable straightforward mounting and plug-in integration with common panel trays, minimizing modification needs and shortening installation schedules. Feature → Business Impact → Application: UL Listed status and a one-year warranty reinforce compliance with electrical codes and vendor support expectations, reducing procurement risk and facilitating faster deployment in regulated industries such as food & beverage, packaging, and automated assembly lines.

FAQs
For seamless integration, plan for a compact footprint (8 in L x 14.25 in H x 7.69 in W) and a 66 lb weight. Use the 77B wiring connection and ensure space for heat dissipation in a NEMA 3R enclosure suitable for indoor-outdoor service. The unit’s aluminum coil and 3 kVA rating align with typical panel boards and 208 V circuits, enabling straightforward mounting in standard control panel racks.
This is a 3 kVA, single-phase transformer operating at 60 Hz with a primary voltage of 208 V and a secondary voltage of 208 V. It features an aluminum coil, an EP design, and a 115 °C rise temperature profile. The device is electrostatically shielded to reduce EMI and supports 208 V distribution in automation and control applications.
Yes. The enclosure is NEMA 3R rated, and the unit is specified as indoor-outdoor with Weathershield protection. This makes it appropriate for outdoor control panels, loading docks, or partially sheltered industrial spaces, reducing the need for additional weatherproof housings and speeding up outdoor installations.
The transformer is UL Listed, which confirms electrical safety compliance for installation and operation in commercial and industrial facilities. Coupled with the NEMA 3R enclosure and electrostatic shielding, these attributes support regulatory conformity, EMI control, and safer panel designs across regulated industries.
The unit carries Eaton’s warranty policy of one year from installation or 18 months from shipment, whichever comes first, reducing maintenance risk. Its robust enclosure, high reliability, and compatibility with standard 208 V systems help minimize downtime and retrofit costs, delivering a favorable total cost of ownership in automation projects.
