Encapsulated transformer
Encapsulated construction provides rugged protection against dust, moisture, and mechanical shock, reducing field failure and maintenance costs. In control panels and distribution enclosures, this translates to longer service intervals and safer operation in challenging environments. The 25 kVA single-phase rating delivers scalable power for automation equipment and machine tools. This enables designers to consolidate power sources, simplify wiring schemes, and meet load requirements without oversizing. Copper windings and a 115°C rise rating offer high thermal tolerance under continuous duty and fault events. This improves reliability in temperature-varied plants and supports broader ambient operating ranges. Voltage ratio of 480 to 2400 V supports diverse industrial applications, enabling efficient step-up/step-down in local circuits. Compact form factor and encapsulation enable easier installation in limited spaces and on existing racks. Compatibility with Eaton catalogs and standard installation practices ensures straightforward procurement and servicing. Certifications-on-request and broad aftermarket support help ensure compliance and minimize downtime during upgrades. In addition, the encapsulated design aligns with common plant-wide modernization programs, reducing integration risk and accelerating project timelines.
