Special features
K13
Feature → Business Impact → Application: K-Factor nonlinear design with ventilated construction reduces harmonic stresses on downstream equipment, delivering improved power quality and cooler operation. In practice, this means lower transformer copper and core losses, reduced cooling requirements, and longer life for drives, PLCs, and other automation hardware used in manufacturing lines. Application includes machine tools, robotics cells, and conveyor systems where clean power translates directly into fewer trips and reduced maintenance costs. Feature → Business Impact → Application: DOE2016 Efficient compliance delivers tangible energy savings and regulatory alignment for facilities pursuing energy-performance targets. Facilities see lower operating costs and easier reporting in audits, particularly in industries with strict energy-use mandates. Application includes automotive assembly plants and process facilities seeking measurable efficiency gains. Feature → Business Impact → Application: A 150 kVA three-phase rating with 480 V primary and 208Y/120 V secondary supports critical loads across automation panels, motor drives, and control rooms. The M-Taps and robust frame (943) simplify wiring and mounting, reducing install time and field engineering effort while increasing system reliability. Feature → Business Impact → Application: UL Listed safety, K13 protection, and a 150°C rise rating enhance reliability in hot environments and during maintenance windows. Application spans data centers, packaging lines, and energy-intensive plants where safety and uptime matter most. Feature → Business Impact → Application: The compact footprint (31.5 in L × 34.5 in W × 51 in H) and 1200 lb weight call for planned rigging and crane access, enabling safer installation in existing electrical rooms and retrofit projects. Application includes retrofit projects and new builds with space-constrained switchgear rooms. Feature → Business Impact → Application: 283B wiring connection and M-Taps provide flexible integration with current distribution schemes, easing panel swaps and future expansions. Application covers industrial automation racks and power distribution centers.
