The KTK-20’s small footprint translates to real panel-space savings in crowded control cabinets, enabling more circuits per enclosure and simplifying enclosure wiring. With a 1.5 in length and 0.41 in diameter, it fits neatly alongside other protection devices while maintaining robust current handling for 20 A circuits. In practice, this means faster panel assembly and easier field retrofits for machine modernization projects in manufacturing lines. Its electrical performance includes a 20 A rating and a 600 V operating voltage with a 100 kAIC interrupt capability, allowing quick fault clearance and minimizing unplanned downtime. The ferrule-end x ferrule-end connections, paired with nickel-plated bronze endcaps and a melamine tube, deliver durable, high-reliability contacts and heat resistance in harsh environments. The non-indicating design reduces panel clutter, expediting inspections and replacements. CE Marked and RoHS compliant construction ensures regulatory readiness, while the small footprint supports modular, scalable protection schemes across multiple machines. Designed for ease of installation, the fuse accommodates standard ferrule terminations, helping technicians reduce wiring time and errors during panel wiring. Industry experience shows that compact, compliant protection devices translate directly into lower total cost of ownership and improved first-pass assembly success in energy-efficient automation projects.
