Hazardous location encapsulation and Class 1 Division 2 construction define the transformer as a purpose-built solution for demanding environments. This design reduces the risk of arcing and containment breaches, supporting safer installations and easier regulatory compliance in chemical plants, refineries, and other facilities with flammable atmospheres. The result is higher asset uptime and lower risk-related costs. The NEMA 3R indoor-outdoor enclosure provides installation flexibility, enabling siting in outdoor pads or protected indoor spaces without sacrificing protection class or performance. This reduces installation time and downstream wiring costs while enabling a single stockable unit for multiple sites. Copper windings paired with a 60 Hz three-phase design deliver consistent voltage and thermal performance, minimizing voltage drop and heat-related stress on connected equipment. The 15 kVA rating aligns with typical shop or panel-board distributions, supporting scalable expansion without transformer swaps. The dual taps at -5% FCBN offer voltage regulation to compensate for supply variations, reducing equipment misoperation and increasing control accuracy in variable-power facilities. Easy access to the wiring connection (70A) and a proven enclosure standard simplify commissioning and field servicing at maintenance intervals. UL Listed certification and the NEMA 3R enclosure support regulatory compliance and peace of mind, while the indoor-outdoor capability lowers total cost of ownership by eliminating the need for separate indoor and outdoor transformers. In practice, this translates to fewer spare parts, faster changeouts, and improved uptime for hazardous-area automation systems.
