Eaton KTS-R-1 Fuse - Class RK1, 200 kAIC, 600V
Part Number: KTS-R-1
Quick Summary
The Eaton KTS-R fuse provides fast-acting overcurrent protection for industrial control panels and power distribution systems. Engineers often confront nuisance trips, crowded enclosures, and the challenge of selecting protection that won’t compromise uptime. Key compliance elements include CE marking and the Class RK1 designation, backed by a 200 kAIC interrupt rating at 600 Vac for demanding fault conditions. With a 1 A rating and a compact 5 in length, it fits neatly into standard holders while delivering reliable, low-energy protection that supports regulatory and OEM requirements.

FAQs
The KTS-R-1 is a 5 inch long, 0.81 inch diameter Class RK1 fuse with a rejection-style design that fits standard fuse holders used in industrial control panels and power distribution enclosures. It pairs well with RK1-compatible holders and common European and North American panel architectures.
A 200 kAIC interrupt rating at 600 Vac means the fuse can safely interrupt very high fault currents without excessive arcing or device damage. This reduces the risk of collateral damage to downstream components, improves system reliability, and supports protection coordination in feeders and main distribution points.
Yes. The KTS-R-1 is CE marked and designated as Class RK1, ensuring alignment with European safety requirements and standard protection class expectations in industrial installations. This combination helps streamline compliance documentation and OEM approvals.
The rejection-style design ensures the fuse can only insert in the correct orientation, reducing mis-wiring risk in crowded panels. During installation, verify the holder matches RK1 rejection features, and ensure space for the 5 in length fits within your enclosure layout to avoid clearance issues.
Using the KTS-R-1 can reduce downtime due to fewer nuisance trips thanks to reliable fast-acting protection, and its compact size supports higher enclosure density, lowering space and replacement part costs. Long-term maintenance benefits include streamlined stocking with a standardized RK1 family and fewer customer service interruptions from protection failures.
