FAQs
For installation, plan a location with sufficient clearance for the 13.38 in width, 19 in height, and 10.52 in depth footprint. Use the 26A wiring connection specification to size conductors and lugs, and ensure the enclosure is a proper indoor-outdoor NEMA 3R rated housing. Verify 208 V primary input and 120/240 V secondary output to match the panel’s load requirements, and secure the transformer to a stable mount with appropriate strain relief and protective cover to maintain UL Listed compliance.
The unit provides a 15 kVA VA rating at 60 Hz, single-phase operation, with a 208 V primary and 120/240 V secondary. It uses an aluminum coil and delivers a 115 °C temperature rise, supporting reliable operation in warm environments. Its NEMA 3R enclosure enables indoor-outdoor use, while UL Listing confirms safety and electrical compliance for industrial applications.
Yes. The transformer comes with an NEMA 3R enclosure designed for indoor-outdoor use, enabling installation in outdoor control cabinets and exposed facility areas. This protection, combined with UL Listed safety, reduces weather-related maintenance and enhances long-term reliability in harsh environments.
Key certification is UL Listed, confirming safety and performance compliance for industrial electrical equipment. The enclosure rating (NEMA 3R) supports weather resistance for indoor-outdoor deployment. The design is intended for 60 Hz, single-phase systems, with a rugged aluminum coil suitable for demanding facilities.
Routine inspection of the enclosure seals and mounting hardware, plus periodic verification of wiring connections, helps maintain UL Listed status and reliability. The encapsulated design reduces dust ingress and simplifies cooling, contributing to increased uptime and predictable maintenance costs, ultimately supporting a favorable return on investment for control and distribution applications.
