FAQs
The transformer fits standard electrical enclosures used in industrial control panels, machine automation cabinets, and utility closets. With a 3 kVA rating, it can support logic circuits and small drives, while its NEMA 3R enclosure allows indoor or outdoor installation. The unit’s fixed voltage configuration simplifies stocking and reduces setup time during panel assembly.
This is a single-phase transformer with a 3 kVA rating and primary voltages of 240 V or 480 V, secondary voltages of 120/240 V, designed for 50–60 Hz operation. It uses aluminum windings, has a fixed tap configuration (no taps), a 115 °C rise rating, and a frame size of 177. Its wiring connection is listed as 3A and it weighs 113 lb.
Yes. It is designed for indoor-outdoor use with a NEMA 3R enclosure and Weathershield suitability for rugged environments. UL Listed and CE marked certifications support regulatory compliance. When installed in appropriate outdoor panels, it provides reliable voltage transformation while resisting moisture, dust, and weather exposure.
UL Listed confirms compliance with U.S. safety standards, while CE marking indicates conformity with applicable European directives. Combined with a NEMA 3R enclosure, these features support regulatory acceptance across multiple regions and ensure safe operation in demanding industrial settings, provided installation and clearances follow manufacturer guidelines.
Encapsulation protects windings from moisture, dust, and vibration, reducing insulation wear and maintenance needs. This translates to fewer service interruptions and lower long-term costs, especially in harsh environments. While weight is higher, the reduced downtime and simpler installation justify the lifecycle savings for automation projects.
