FAQs
Install the KTS-R-350 in standard RK1-compliant fuse blocks within electrical panels. Verify the panel enclosure supports a 11.63 in long, 2 in by 2 in footprint and that the single-element fuse aligns with the conductor size. Use proper lockout/tagout procedures and ensure the upstream protective device is coordinated to avoid nuisance trips.
Key specs include a 350 A amperage rating, 200 kAIC interrupt rating at 600 V, and a 600 V voltage rating. This fast-acting, current-limiting RK1 fuse is designed to protect power distribution feeders and switchgear while limiting fault energy to downstream equipment.
Yes. The 350 A rating and 200 kAIC interrupt capacity make the KTS-R-350 suitable for protecting high-inertia motor feeders and large distribution feeders. Its RK1 class and current-limiting characteristics help minimize mechanical and electrical stress during fault events, improving motor life and system reliability.
The KTS-R-350 is CE marked and RoHS compliant, supporting global regulatory requirements. For verification, users can consult Eaton’s RoHS tool and the Bussmann full-line catalogs to confirm compliance details for specific markets and product revisions.
The KTS-R-350’s current-limiting, high interrupt ratings, and knife blade design reduce fault energy and simplify replacement, lowering downtime and maintenance costs. Its compatibility with standard RK1 fuse blocks supports quick swaps and inventory consolidation, contributing to lower total cost of ownership in high-availability facilities.
