Eaton Specification Sheet - T20P11S1516CUZZ
Feature Open-core ventilated design enables superior heat dissipation, reducing hotspots and maintaining stable load performance. Business Impact This translates to longer MTBF, reduced thermal stress on windings, and lower cooling costs in control cabinets. Application Ideal for high-heat environments in manufacturing lines where reliable uptime is critical. Feature Copper windings provide low resistance and high electrical conductivity, improving efficiency and minimizing copper losses at full load. Business Impact Resulting energy savings and improved thermal margin, contributing to lower operating expenses over the transformer’s life. Application Suitable for continuous-duty distribution needs in automated systems and machine centers. Feature Wide voltage taps (1 at +5% FCAN, 2 at -5% FCBN, 2 at +2.5% FCAN, 4 at -2.5% FCBN) allow precise voltage regulation, accommodating fluctuating supply conditions. Business Impact This reduces voltage drift at critical loads, protecting sensitive controls and reducing nuisance tripping. Application Useful in facilities with variable feed voltages or non-symmetric supply conditions. Feature UL Listed and NEMA TP-1 efficient certification ensures safety and energy efficiency compliance. Business Impact Facilitates regulatory approvals, simplifies audits, and supports energy-performance programs. Application Ideal for modernizing panels while meeting code requirements in industrial plants. Feature Dry-type, single-phase, 60 Hz operation with 15 kVA rating supports quick integration into standard automation architectures. Business Impact Streamlines procurement and commissioning, reducing design time and installation complexity. Application Fit for control panels, motor starters, and panel boards in factory floors. Feature Physical dimensions and copper-wound frame 816C provide robust mechanical integrity and predictable mounting in tight spaces. Business Impact Aids in space planning and replacement planning for retrofit projects. Application Beneficial in retrofit upgrades of aging panels where fit and performance matter.
