Feature DT-3 dry-type design reduces fire risk and simplifies maintenance, delivering safer operation in indoor spaces and control cabinets. This translates to lower lifecycle costs and easier compliance with enclosure rules, while avoiding oil leaks and environmental concerns. Feature 112.5 kVA rating with 480 V primary and 208Y/120 V secondary enables a single unit to feed multiple loads with tight voltage regulation. The compact footprint and frame 917 dimensions fit standard racks and panels, reducing space needs in machines and distribution boards. Feature Copper windings improve conductivity and thermal performance, enhancing efficiency and resilience under short-term overloads. Copper construction also supports longer service life in harsh industrial environments, lowering replacement cycles. Feature Tap settings of 2 at +2.5% and 4 at -2.5% FCAN/FCBN provide precise voltage regulation across load swings. This capability minimizes nuisance tripping, protects sensitive equipment, and eases integration with variable-speed drives and PLC-powered machines. Feature UL Listed certification and rugged frame 917 support safe installation and consistent performance in regulated environments. With 60 Hz rating and 150°C rise, this transformer handles typical plant duty while the large footprint and heavy weight demand proper mounting and lifting planning. Feature Compatibility with standard distribution panels and cabinets simplifies retrofits and reduces commissioning time, delivering faster ROI for industrial automation projects.

FAQs
For 480 V systems, plan for a rigid mounting surface that accommodates the 1431 lb weight and 24.67 in length by 32.02 in height and 31.44 in width. Ensure clearance for cooling, access to the taps at +2.5% and -2.5%, and adherence to enclosure requirements. Use appropriate lifting equipment and verify room temperature is suitable for a 150°C rise rating.
Key specifications include a 112.5 kVA rating, 60 Hz frequency, three-phase configuration, 480 V primary, 208Y/120 V secondary, copper windings, DT-3 design, frame 917, and a 150°C temperature rise. It features two taps at +2.5% FCAN and four taps at -2.5% FCBN to regulate output under varying loads.
Yes. Its dry-type DT-3 design with a compact frame and copper windings is well-suited for panel boards and MCCs. The 112.5 kVA rating supports multiple feeders, and the voltage regulation taps help maintain stable downstream voltages for motor starters, PLCs, and control circuits across varying load conditions.
This transformer is UL Listed, confirming compliance with recognized safety standards for electrical equipment. While CE and IP ratings are not specified in the dataset, regional safety and environmental requirements may vary. Verify local codes and manufacturer guidance to ensure full regulatory alignment for your installation environment.
The 112.5 kVA dry-type design delivers reliable performance with oil-free operation, reducing maintenance and risk of leaks. Copper windings improve efficiency and heat management, lowering energy losses. With minimal moving parts and UL safety certification, you can expect longer service intervals, easier inspections, and predictable operating costs in factory automation and distribution applications.
