Encapsulated EPZ construction improves safety by sealing windings from dust, moisture, and chemical exposure. This design reduces arcing risk and heat buildup, boosting uptime and compliance in Class I Division 2 locations. Ideal for instrumentation panels and motor controllers in oil and gas facilities and chemical plants. The 0.5 kVA rating provides a compact yet sufficient power source for small control circuits, enabling efficient panel design and lower enclosure footprint. Flexible 120/240 V primary to 12/24 V secondary wiring supports common industrial power sources and low-voltage loads, reducing the need for multiple transformers in mixed-voltage systems. Aluminum coil construction offers corrosion resistance and lighter weight, improving outdoor installation durability and overall maintenance costs. A NEMA 3R enclosure with EPZ insulation delivers weatherproof protection for indoor-outdoor use, enabling safer outdoor equipment and simplified installation in harsh environments. UL Listed certification confirms compliance with essential safety standards, while the 57H frame size ensures compatibility with common mounting footprints and field replacement workflows, saving time during maintenance cycles. Temperature rise rating of 115 °C supports robust performance in hot industrial spaces, minimizing derating and extending service life in demanding applications.
