FAQs
This unit features a 480 V primary and a 208Y/120 V secondary, designed for standard three-phase input. Wiring connections use 283B and a 31.5 in L × 34.5 in W × 51 in H footprint, enabling straightforward integration into existing switchgear and motor control centers while maintaining safe clearance and ventilation.
The transformer is UL Listed and DOE2016 Efficient compliant. UL Listing provides recognized safety assurance for electrical equipment, while DOE2016 efficiency targets help reduce energy consumption across operating hours. Together, they support regulatory alignment, safer operation, and lower life-cycle energy costs.
K-Factor nonlinear design enhances fault current handling and improves thermal distribution within the core and windings. When paired with ventilated construction and a 115 °C rise rating, it maintains stable temperatures under diverse load profiles, reducing thermal stress on insulation and extending transformer life in demanding manufacturing and processing environments.
Plan for the unit’s 1200 lb weight and its dimensions (31.5 in L × 34.5 in W × 51 in H). Ensure adequate floor loading, mounting clearances, and ventilation. Verify wiring compatibility with 283B terminals and align with local codes and space constraints to simplify retrofits in aging panels or new automation lines.
With DOE2016 efficiency and UL safety, expect energy savings over the device’s life, contributing to lower operating costs. The ventilated design reduces cooling needs, and the robust 112.5 kVA rating supports scalable automation loads, delivering improved uptime and favorable total cost of ownership in mid-size manufacturing or data-center adjacent applications.
