Resin-encapsulated construction reduces moisture ingress and vibration-induced wear, boosting mean time between failures and lowering maintenance costs in damp or dusty environments. This leads to improved uptime for critical processes in chemical plants, refineries, and mining sites. The 480 Vac primary to 400Y/231 Vac secondary configuration supports standard facility distributions, enabling fast integration with existing switchgear and panel boards, reducing installation risk and cross-system voltage mismatch. Copper windings enhance efficiency and thermal performance, delivering improved energy savings and cooler operation in 60 Hz systems, with a 50°C ambient rating that broadens siting options in hot environments. A NEMA 4 painted steel enclosure provides rugged outdoor and indoor protection, simplifying compliance checks and reducing enclosure-related contamination risk. Classified for Hazardous/Classified Locations under NEC/CEC, it meets stringent regulations while supporting scalable power distribution in industrial plants.

FAQs
It is designed for Class I, Division 2 environments with NEC/CEC compliance and a NEMA 4 enclosure, making it suitable for chemical plants, oil & gas facilities, and mining operations requiring rugged, safety-focused power conversion.
Yes. The unit uses a standard three-phase 480 Vac primary to 400Y/231 Vac secondary configuration with copper windings, allowing straightforward integration into common switchgear, panels, and downstream distribution in facilities already employing Eaton/Crouse-Hinds products.
NEC/CEC compliance, Area classification for Hazardous/Classified Locations, Class I, Division 2 hazardous-location rating, and a NEMA 4 enclosure rating, ensuring suitability for harsh environments and compliance with regulatory requirements.
Resin encapsulation protects windings from moisture and contaminants, reducing thermal and electrical stress, lowering maintenance cycles, and enhancing uptime in challenging environments such as chemical plants and offshore facilities.
Plan for appropriate mounting space given the unit’s dimensions (38.88 in L x 32.25 in W x 33.11 in H), weigh approximately 3170 lb, ensure proper ventilation and clearance, and verify compatibility with existing 480 Vac distribution panels and downstream 400Y/231 Vac loads.
