FAQs
For proper installation, consider its 113 lb weight, footprint dimensions, and the NEMA 3R enclosure designed for indoor-outdoor use. Ensure clearances per manufacturer guidance, secure mounting on a sturdy base, and proper ventilation. With 3E wiring and aluminum windings, wiring should follow standard practice for single-phase, 60 Hz systems and include appropriate protection devices.
This unit is a single-phase transformer rated at 5 kVA, operating at 60 Hz. Primary voltage options are 120 V or 240 V, and the secondary is 120/240 V. It uses an aluminum coil and has a 115 °C rise, making it suitable for continuous operation in typical industrial control environments with stable voltage delivery.
Yes. The transformer features a NEMA 3R enclosure and Weathershield designation for indoor-outdoor service. UL Listed certification adds regulatory confidence, while the rugged enclosure and weather tolerance enable reliable operation in outdoor control panels, equipment bays, and damp environments.
Key certifications include UL Listed, with a NEMA 3R enclosure rating for indoor-outdoor use. The unit operates at 60 Hz, is a single-phase design, and uses 120/240 V primary and 120/240 V secondary voltages, aligning with common industry standards for control and power distribution equipment.
The encapsulated aluminum-wound construction, rugged EP design, and UL/NEMA-rated enclosure reduce field maintenance and replacement costs. Its reliability in indoor-outdoor environments minimizes downtime, supports longer service intervals, and simplifies spare-part inventories, delivering a favorable total cost of ownership for control panel and equipment fleets.
