Encapsulated, general-purpose construction provides rugged protection against moisture and dust. This translates to lower maintenance costs and fewer field faults, especially in dirty or damp environments. It is well-suited for installation inside control panels and distribution enclosures where space is at a premium. 15 kVA rating with 480 V primary and 120/240 V secondary enables efficient power distribution to controls and auxiliary equipment. The copper windings deliver better efficiency and reduced copper losses, improving overall system performance and heat management. This makes it a strong fit for machine controls, PLC racks, and panel boards in manufacturing lines. UL Listed transformer housed in a NEMA 3R, Grade 304 stainless steel enclosure delivers indoor-outdoor capability. The enclosure protects against weather, corrosion, and accidental contact, supporting code compliance and safer installations. Suitable for outdoor switchgear rooms or rugged plant floors where cleanliness cannot be guaranteed. Dual tap capability (+2.5% and -2.5%) enables precise voltage regulation to compensate line drops and feeder losses. By maintaining secondary voltage within tolerance, equipment experiences less stress and longer life. This feature is particularly valuable in long cable runs or facilities with variable loads. Single-phase, 60 Hz operation with 16 A wiring simplifies integration into existing power architectures while maintaining reliability. A 115 °C rise rating confirms solid thermal performance at full load, reducing risk of overheating. Eaton backs this transformer with a 1-year warranty from installation or 18 months from shipment, ensuring long-term support.
