KTK-R Spec Sheet
Current-limiting fast-acting operation reduces fault energy quickly, protecting wiring and downstream components. This minimizes downtime and repair costs during short circuits. Ideal for industrial control panels, street lighting, and distribution networks. Dual-element design improves surge resistance and reliability, delivering higher uptime in demanding environments. 30 A amperage rating aligns with common control circuits, reducing nuisance trips while maintaining protective headroom. The 200 kAIC interrupt rating supports high fault currents typical in switchgear and feeders, enhancing system safety. Rejection-style ferrule-end connections prevent incorrect replacements and simplify field wiring, improving installation reliability. Rated for 600 V and RoHS/CE/UL certifications, the KTK-R-30 provides broad compatibility and global compliance for modern electrical installations. Compatible with Bussmann series components, it streamlines stocking and maintenance across sites.

FAQs
KTK-R-30 uses ferrule end connections (Ferrule end x ferrule end) designed for quick, reliable field wiring. The standard ferrule-terminals ensure a secure termination with Bussmann-series compatible components, reducing installation errors. This design also facilitates straightforward field replacement and minimizes rework in control panels and distribution cabinets.
KTK-R-30 provides a 200 kAIC interrupt rating, meaning it can safely interrupt high-energy fault currents. As a current-limiting fast-acting fuse, it sharply reduces peak fault energy, limiting damage to conductors and neighboring devices. This behavior translates to shorter downtime and easier upstream protection coordination in 600 V systems.
Yes. With a 30 A rating and 600 V capability, it is well-suited for machine control, industrial controls panels, street lighting, general lighting, capacitors, and distribution circuits. The rejection-style design helps prevent mis-matching during maintenance, while dual-element construction bolsters reliability in fluctuating loads typical of outdoor lighting and panel assemblies.
KTK-R-30 is UL Listed, CSA Certified, and CE Marked RoHS Compliant. These certifications verify safety, performance, and environmental compliance, enabling global deployments across North America and Europe. Meeting these standards helps streamline procurement, reduces compliance risk, and supports regulatory approvals in industrial facilities.
The fuse is designed for long life with minimal maintenance, reducing preventive service cycles. Its high interrupt rating and robust current-limiting protection lower the likelihood of collateral damage during faults, translating to lower repair costs and downtime. Standardized packaging and compatibility with Bussmann-series components also improve spare part availability and overall return on investment for multi-site deployments.
