Feature–Business Impact–Application: Hazardous location encapsulation with Class I Division 2 design provides enhanced safety for personnel and equipment in potentially explosive atmospheres. The rugged enclosure reduces ingress risk and supports safer maintenance in the field. This construction is ideal when installing in chemical plants, refineries, or offshore facilities where reliability and certification are nonnegotiable. Feature–Business Impact–Application: 45 kVA three-phase transformer with a 480 V primary and 240/120 V secondary supports standard industrial power distribution with minimal conversion losses. This configuration enables direct feeding of motor starters, controls, and lighting circuits from a common source while preserving voltage integrity across loads. It suits panel boards and distribution equipment in manufacturing cells. Feature–Business Impact–Application: Tap changer 2 at -5% FCBN allows precise voltage regulation under fluctuating supply conditions, improving motor performance and reducing nuisance trips. Operators can fine-tune outputs to maintain stable downstream voltages in long runs or remote facilities. This is especially valuable for sensitive drives and control circuits in process lines. Feature–Business Impact–Application: NEMA 3R enclosure with Indoor-Outdoor Weathershield delivers weatherproof protection for both indoor and outdoor installations. The robust enclosure reduces corrosion risk, supports installation in damp or outdoor environments, and simplifies maintenance scheduling. Ideal for exterior pad-mounted applications near loading docks or outdoor switchgear. Feature–Business Impact–Application: Aluminum windings, a 60 Hz frequency rating, 244H frame, and UL Listed certification ensure efficient operation, reliability, and regulatory compliance. The device weighs 762 lb and has precise dimensions (14.66 in L, 26.49 in H, 28.17 in W) for planning and rack-mount or stand-alone installation. A one-year warranty (or eighteen months from shipment) supports procurement risk management.

FAQs
For hazardous locations, ensure a Class I Division 2 compliant installation in a protected area with proper clearance around the encapsulated transformer. Use the NEMA 3R enclosure for outdoor or damp environments, verify correct amperage and conductor sizing for the 52A wiring connection, and follow local codes for hazardous area installations to maintain UL Listed status.
The unit provides a 480 V primary and dual secondary outputs of 240 V and 120 V. This configuration supports feeding motor starters, controls, and distribution panels directly, reducing the need for intermediate transformers and minimizing voltage drop along feeders. Ensure downstream equipment is rated for these voltages and use appropriate protection devices on both primary and secondary sides.
