Special features
K13
The K-Factor nonlinear ventilated design minimizes harmonic-related heating and improves energy efficiency under variable loads. This translates to measurable reductions in heat generation and cooling costs, especially in facilities with mixed load profiles. It is well suited for control panels, process lines, and industrial cabinets where dependable, low-emission operation matters. DOE2016 Efficient compliance helps facilities meet energy-use benchmarks and qualify for incentives, driving a lower total cost of ownership over the transformer’s life. The 112.5 kVA rating with a 480 V primary and 208Y/120 V secondary enables scalable power distribution for growing plants and data centers, reducing the need for mid-cycle equipment upgrades. UL Listed certification supports safety compliance, essential for regulated industries and critical infrastructure. Ventilated cooling improves thermal management during peak loads, extending service life and reducing maintenance intervals. The 283B wiring connection aligns with standard bus and panel configurations, enabling faster installation and reducing field modification needs. The K13 feature adds robust fault tolerance, beneficial in high-demand applications and harsh environments. This combination delivers predictable performance, improved reliability, and a smoother path to compliance and cost savings.
