Encapsulated hazardous-location design provides safety and reliability. The encapsulation reduces moisture intrusion and arcing potential, translating to lower risk and simplified compliance for Class I Division 2 environments. Applications include oil and gas facilities, chemical plants, and mining operations where outages are costly and safety standards are strict. Three-phase 480 V primary to 208Y/120 V secondary with a 45 kVA rating and 60 Hz frequency gives stable power for controls and drives. The -5% FCBN two-tap feature lets technicians compensate for supply variations without swapping components, reducing installation time and voltage-related issues. Aluminum windings and an 80°C temperature rise support robust heat management in a rugged frame 245H with a NEMA 3R enclosure for indoor-outdoor service. Weather tolerance and Weathershield Indoors-Outdoor design, plus a 66A wiring connection, support straightforward integration with existing switchgear and panels. Warranty and service details—Eaton’s 25-000 policy offers one year from installation or 18 months from shipment—help reduce lifecycle risk and sustain uptime across a broad range of industrial environments.
