Hazardous location compatibility is built into the Z48N11S15CU, delivering Class I Division 2 protection with an encapsulated EPZ design. Business impact: reduced regulatory risk and safer operation of equipment in chemical plants, refineries, and similar facilities. Application: ideal for power distribution in zones where flammable atmospheres exist, enabling reliable operation without excessive enclosure heating. Copper windings and a 115 °C rise support efficient heat management, extending insulation life and lowering maintenance costs. This translates to longer service intervals and lower total cost of ownership in demanding environments. The NEMA 3R enclosure and Weathershield capability allow indoor-outdoor installation, simplifying site planning and reducing the need for additional housings. Compatibility with standard 524H wiring connections makes integration straightforward for controls and motor loads. Installation is streamlined thanks to single-phase 480 V input and 120/240 V secondary, reducing wiring complexity and risk of misconfiguration. The unit’s FR180H insulation rating and 15 kVA rating align with typical plant transformer footprints, offering a compact solution that maintains performance under peak loads. Certifications from CSA and UL further reassure auditors and operators, while the included warranty supports reliability commitments. This transformer is well-suited for oil, gas, and chemical processing environments where safety, longevity, and compliance matter most.
