FAQs
The KTK-R-6 uses ferrule-end connections and a compact 1.5 inch overall length with 0.41 inch width and height, designed for standard Bussmann Class CC holders. It operates at 600 V and 6 A, and ships in packs of 10, making it straightforward to fit into common panel layouts and maintenance inventories.
KTK-R-6 is a current-limiting fast-acting fuse, so fault currents are interrupted quickly to minimize arc energy and downstream damage. Its 200 kAIC interrupt rating provides strong short-circuit protection, with response governed by the defined time-current curve, ensuring reliable protection at and near the 6 A rating.
Yes. With a 600 V rating, 6 A current rating, and 200 kAIC interrupt capability, the KTK-R-6 is well-suited for industrial control panels, street lighting, capacitors, and distribution networks, delivering robust protection in diverse environments while meeting regulatory expectations.
The KTK-R-6 is UL Listed, CSA Certified, CE Marked, and RoHS Compliant. These certifications support regulatory compliance in North America and Europe, simplify supplier qualification, and bolster confidence in safety and reliability across multinational installations.
Stocking is simplified by standard packaging of 10 units, while the non-indicating, rejection-style design reduces the risk of incorrect replacements. Its robust ratings and compatibility with Bussmann series components help lower downtime and streamline procurement for maintenance teams and OEM projects.
