FAQs
The KON90 is a knife-blade fuse designed for Edison series holders and standard DIN-rail panel applications. It arrives in a 5‑pack and fits typical Bussmann Edison base hardware, allowing quick field replacements and straightforward integration into existing protection schemes without specialized tooling.
The 10 kAIC interrupt rating enables safe interruption of high-energy faults, reducing the risk of arcing, contact welding, and downstream damage. This is particularly important in panels connected to robust power sources, where reliable fault isolation preserves equipment and minimizes costly downtime during maintenance or fault conditions.
Yes. With a 250 V rating, the KON90 is appropriate for low-voltage automation control circuits, motor starters, and panel feeders. Always verify that the circuit’s current demand stays within the 90 A amperage rating and consider coordination with upstream protection to ensure selective tripping and safe shutdowns.
Non-indicating fuses require indirect status monitoring. Use panel indicators, fuse switch positions, or integrate with remote sensing to verify fuse health. If direct indication is essential, pair the KON90 with compatible indicators or an protection system that provides real-time fault alerts and diagnostic visibility.
Keep a five-pack readily available and categorize by amperage, voltage, and class to prevent mis-picks. During replacement, inspect the fuse holder for corrosion and ensure proper knife-blade alignment. Maintain documentation on CE compliance and Class K5 specs to support cross-site procurement and reduce procurement cycles.
