Eaton KTS-R-35 Fuse - 200 kAIC at 600 Vac RK1
Part Number: KTS-R-35
Quick Summary
Eaton KTS-R-35 fuse is a fast-acting, current-limiting protection device for industrial power circuits. Engineers frequently struggle to select fuses that clear faults quickly while avoiding nuisance trips in control panels and motor feeders. This CE marked device follows Class RK1 design principles, delivering predictable coordination with upstream protection and a robust 200 kAIC interrupt rating at 600 V. With ferrule-end connections and a compact 5.5 in length profile, it simplifies installation and field replacement, reducing downtime and service costs. Positioned for reliability in harsh plant environments, the KTS-R-35 supports efficient panel design and long-term protection for critical loads. Its melamine glass tube construction and non-indicating design minimize maintenance cycles in busy facilities.

Bussmann series KTS-R 600 V Class RK1 fuse data sheet no. 1044
The KTS-R-35 delivers 35 A current-limiting protection with a 200 kAIC interrupt rating at 600 VAC. This combination rapidly clears faults, protecting downstream devices like drives, contactors, and relays while reducing arc energy and collateral damage. Ideal for motor control centers, switchgear, and distribution panels where fast, reliable fault interruption is essential. Class RK1 construction and ferrule-end connections provide easy, code-compliant installation with robust terminations. The ferrule design minimizes termination failures and simplifies replacement during maintenance, reducing downtime in industrial environments. Compact form factor—5.5 in length, 1 in width—and melamine glass tube material enable tight panel layouts while maintaining durability in high-temperature environments. Non-indicating design and standard packaging simplify inventory management and reduce installation confusion in multi-fuse assemblies. Access to Eaton Bussmann data sheets and catalogs supports design validation, compliance checks, and faster engineering sign-off.

FAQs
The KTS-R-35 is designed for ferrule-end x ferrule-end terminations, compatible with Bussmann-series protection schemes and standard panel assemblies. It fits in control panels and motor drives where the 5.5 in length and 1 in width support compact layouts. Use ferrule-end wiring practices to ensure solid termination and reliable mechanical fitment in industrial enclosures.
The KTS-R-35 provides a 200 kAIC interrupt rating at 600 VAC, meaning it can safely interrupt short-circuit currents up to 200 kiloamps. This level of interrupt capability protects upstream equipment, minimizes arc energy, and reduces the risk of collateral damage in high-current fault events, which translates to lower downtime and maintenance costs.
Yes. With a 35 A rating, 600 V maximum voltage, and fast-acting current-limiting characteristics, the KTS-R-35 is well-suited for motor protection in control panels and motor feeder circuits. Its Class RK1 construction ensures predictable coordination with upstream devices, supporting safe starting sequences and selective protection in drive assemblies.
The KTS-R-35 is CE marked, aligning with European safety and performance requirements. It follows the Class RK1 fuse designation and Bussmann-series design conventions, providing standardized performance for reliability and compliance in industrial electrical protection schemes.
Install the KTS-R-35 using ferrule-end terminations in clean, clipped panel spaces. Verify correct amperage rating, voltage rating, and interrupt rating for the application. During maintenance, replace only with a like-for-like 35 A, 600 V RK1 fuse, and inspect ferrule connections for signs of wear or overheating to maintain consistent protection and avoid spurious trips.
