DT-3 dry-type design reduces cooling loads and simplifies installation in restricted spaces, lowering energy costs and enabling safer indoor use in machine rooms and control panels. Benefit: predictable performance with less auxiliary cooling equipment and a smaller footprint for panel builders and OEMs. The 45 kVA rating with a 480 V primary and 208Y/120 V secondary delivers dependable media conversion for mid-size feeders and process loads, reducing panel count and enabling streamlined wiring and testing in manufacturing facilities. Aluminum windings paired with an electrostatic shield improve efficiency and EMI/grounding integrity, while withstanding 150 °C rise, enhancing reliability in hot industrial environments. The totally enclosed non-ventilated enclosure minimizes dust ingress and moisture exposure, supporting longer service intervals and safer indoor operation under dusty plant conditions. The dual tap set—2 at +2.5% FCAN and 4 at -2.5% FCBN—provides voltage regulation to counter supply variations, reducing voltage-related outages and equipment misoperation. Frame 916AN and a weight of 791 lb indicate a robust, field-ready asset that fits standard mounting schemes and allows straightforward installation with common hoisting equipment. UL Listed certification reinforces compliance with safety standards, enabling smoother procurement and commissioning. In practice, these features translate to lower maintenance costs, faster uptime, and a stronger return on investment for industrial power distribution projects.
