FAQs
Install the transformer within a suitable enclosure that accommodates a 277 VAC primary and 208 VAC secondary. Provide proper clearance for heat dissipation, mount using standard hardware, and connect lines to the rated terminals. Ensure the panel wiring aligns with 1PH configurations and observe manufacturer torque specs for copper windings to prevent overheating.
The unit is a 5 KVA, single-phase transformer with 277 VAC primary and 208 VAC secondary. It uses copper windings and features a totally enclosed non-ventilated design with a 150°C rise rating. Listed weight is 1 lb for reference in documentation; verify actual installation weight in the serial documentation.
Certification details are marked as 'Contact Manufacturer' for this model. In practice, industrial transformers commonly pursue CE and UL marks; IP ratings and SIL readiness depend on the specific enclosure and installation. Always confirm the exact approvals with Eaton procurement or your compliance team before installation.
A totally enclosed non-ventilated design reduces the need for external cooling and fan maintenance, lowering ongoing maintenance costs. Copper windings improve thermal performance and efficiency under load, while the sealed enclosure minimizes dust ingress. These factors collectively support longer service life and lower total cost of ownership in panel applications.
