Open-core ventilated design enhances cooling, reducing hot spots and extending transformer life. This translates to lower maintenance costs and greater reliability in continuous-operation panels used in manufacturing lines, automation racks, and distribution boards. Three-phase operation at 60 Hz with a 480 V primary and 208Y/120 V secondary delivers stable, scalable power for motors, drives, and control electronics, improving overall system performance and reducing voltage-related downtime. Taps at +2.5% and -2.5% provide practical voltage regulation for fluctuating loads, enabling downstream equipment to operate within spec without oversized protection schemes. Aluminum windings and a sturdy 908S frame optimize durability and installation flexibility in constrained spaces, while UL Recognized and NEMA TP-1 compliance support safe integration. The 15 kVA rating aligns with common mid-range panel requirements and helps standardize procurement across multiple lines.

FAQs
Install the transformer on a flat, level mounting surface within the panel using the provided hardware. Ensure proper clearance for ventilation, connect the 480 V primary supply and 208Y/120 V secondary outputs per the wiring diagram, and observe all safety clearances. Verify taps are set to the correct voltage for your load and confirm UL and NEMA TP-1 compliance during commissioning.
This unit provides 15 kVA rated power, 60 Hz, three-phase operation with a 480 V primary and 208Y/120 V secondary. It features taps at +2.5% and -2.5% to accommodate voltage variations. These specs support stable downstream voltages for motors and controls, improving efficiency and reducing nuisance tripping or undervoltage conditions in automation equipment.
Yes. It utilizes a dry-type open-core ventilated design, which promotes effective cooling and reliable operation in industrial spaces. UL Recognized and NEMA TP-1 compliant construction further ensures safety and performance, while the frame and aluminum windings provide durability under continuous duty and variable loads commonly found in production lines.
The unit is UL Recognized and NEMA TP-1 compliant, reflecting alignment with established electrical safety and efficiency standards for industrial transformers. These certifications support safe installation in control panels, meet regulatory expectations, and facilitate approval processes in facilities following strict electrical codes.
Benefit from a low-maintenance, robust dry-type design with a 150 °C rise rating and aluminum windings for enduring performance. The 1-year warranty (or 18 months from shipment) adds financial protection, while the open-core, ventilated design reduces cooling-related energy losses. These factors contribute to longer service intervals and a favorable total cost of ownership for panel modernization programs.
