FAQs
For panel installations, mount the 68P frame unit within a NEMA 3R rated enclosure and plan wiring around the 511G connection. Ensure adequate clearance for heat dissipation given the 2 kVA rating, and follow UL-listed wiring practices to maintain compliance. Use the 60 Hz single-phase input (480 V) and route output to 277 V circuits with appropriate protection devices.
It is a single-phase, 2 kVA transformer with a 480 V primary and 277 V secondary, designed for industrial control and distribution. Aluminum winding reduces weight and improves heat dissipation. The encapsulated EP design with a NEMA 3R enclosure supports reliable operation in both indoor and outdoor environments.
Yes. The NEMA 3R enclosure and indoor-outdoor rating enable outdoor installations, rain exposure, and dust resistance. Plan for weather protection where possible, and verify voltage rating alignment with system requirements to maintain safety margins and compliance.
The transformer is UL Listed, with a NEMA 3R enclosure and 60 Hz single-phase operation. These certifications validate safety, reliability, and suitability for regulated industrial environments, easing procurement audits and end-user certification processes.
With a robust encapsulated design, rugged enclosure, and aluminum windings, maintenance requirements are reduced compared to oil-filled or non-encapsulated units. The 2 kVA rating supports scalable control power without frequent replacements, delivering lower total cost of ownership over the equipment lifecycle.
