Indoor-Outdoor
Encapsulated design with electrostatically shielded windings provides robust protection against moisture, dust, and EMI, reducing maintenance costs and improving panel reliability in harsh environments. This translates to fewer field failures and longer service intervals for critical automation equipment, such as motors and drives, in control rooms or outdoor installations. The 25 kVA, 60 Hz, single-phase rating supports moderate automation loads, enabling engineers to consolidate transformers within a single panel while maintaining clean, stable voltage for sensitive electronics. With primary 120/240 V input and secondary 120/240 V output, wiring remains straightforward for standard electrical distribution practices, reducing installation time and cabinet footprint. The NEMA 3R enclosure and Weathershield design make outdoor and semi-exposed spaces feasible, simplifying site planning and reducing the need for separate indoor/outdoor units. UL Listed certification ensures safety compliance across procurement and service, while the 115 °C rise rating confirms robust thermal performance under load. The 182 frame and 90B wiring provide compatibility with common mounting and wiring schemes, easing retrofit projects and spare-parts planning. Finally, the unit’s substantial 371 lb weight supports durable, vibration-resistant operation in industrial settings, contributing to long-term reliability and uptime.
