FAQs
KTK-R-6/10 uses ferrule-end connections and is designed for Class CC fuse holders. Install in standard panel blocks compatible with Bussmann ferrule-end fuses, ensuring proper seating and alignment. Verify the enclosure rating and ensure the circuit voltage is within 600 V and the current rating is appropriate for the protected load. Consult the time-current curve from the datasheet to coordinate selectivity with upstream protections.
The 200 kAIC interrupt rating indicates the fuse can safely interrupt very high fault currents without excessive arcing. This protects downstream devices, wiring, and transformers from catastrophic damage and reduces the risk of collateral failure during faults. It is particularly important in systems with high short-circuit currents or large distribution panels.
Yes. The 0.6 A, 600 V rating and current-limiting, fast-acting characteristics make it suitable for street lighting gear, general lighting, and capacitor/distribution networks. Its high interrupt rating and dual-element design help coordinate protection with feeders and capacitors, while the rejection-style ferrule ends simplify correct replacement in standard housings.
KTK-R-6/10 is UL Listed and CSA Certified, with CE Marking and RoHS compliance. These certifications support regulatory compliance for North American and global deployments and help streamline safety documentation,_component traceability, and environmental requirements in procurement specifications.
The current-limiting, fast-acting design reduces fault energy, minimizing downtime and downstream damage. Its rejection-style ferrule end and standardized Class CC form factor simplify stocking, replacement, and maintenance. Over time, this can lower maintenance labor costs, extend equipment life, and improve overall system uptime in industrial installations.
