Ferrule design
Feature → Business Impact → Application: The KTS-R-40 is a fast-acting current-limiting fuse rated at 40 A and 600 V, delivering rapid interruption of fault currents. The business impact is reduced arc energy and minimized collateral damage to downstream equipment, translating into shorter repair times and higher overall line efficiency in automation frameworks. In application, it suits motor starters, drives, and branch circuits in compact control panels where space is at a premium. Feature → Business Impact → Application: Ferrule end terminals on both ends provide sturdy, vibration-resistant connections and repeatable terminations. The business impact is faster, error-free wiring and lower torque-related damage during service tasks, boosting maintenance productivity. In application, these ferrule ends align with standard RK1 fuse blocks and common panel layouts, enabling rapid installation and straightforward stock management. Feature → Business Impact → Application: With a 200 kAIC interrupt rating at 600 Vac, the KTS-R-40 can safely interrupt large fault currents. The business impact is enhanced safety, reduced risk of cascading trips in high-availability lines, and lower insurance exposure in critical automation sequences. Applications include feeders, branch circuits in machine rooms, and panels connected to high-current motors or drives. Feature → Business Impact → Application: The melamine glass tube provides robust insulation and predictable performance under temperature and vibration. Coupled with a single-element design, this fuse delivers consistent interruption characteristics and simpler sourcing. Applications include standard industrial control panels, where compact dimensions (1.5 in W x 1.5 in D x 5.5 in H) fit limited spaces. Feature → Business Impact → Application: CE marking confirms compliance with European electrical safety requirements, while standard packaging and RK1-class design streamline procurement and stock rotation. The 1-element ferrule-end fuse is easy to spec against Bussmann data sheets and catalogs, supporting faster design cycles and consistent spares in multinational installations.

FAQs

The KTS-R-40 uses ferrule-end terminals designed for standard RK1 fuse blocks; ensure the holder supports ferrule-terminals and 40 A fuses to guarantee proper seating, rated interruption, and safe maintenance.
It is rated for 40 A with a 200 kAIC interrupt rating at 600 Vac, and a voltage rating of 600 V. This pairing delivers fast fault interruption while protecting downstream equipment and reducing arc energy in high-current environments.
Yes. The fuse is CE marked and Class RK1, designed for 600 V systems and European installations. Verify compatibility with your panel's fuse blocks and ensure proper ratings to maintain compliance and safety.
Ferrule ends provide quick, secure terminations that resist loosening from vibration and reduce wiring mistakes. This translates to faster field replacements and lower commissioning time, especially in dense control panels or retrofit projects.
By delivering rapid fault interruption and reducing downtime, the KTS-R-40 helps lower maintenance costs and extend equipment life. Its 40 A rating matches common control circuits, while 200 kAIC interrupt rating minimizes energy let-through during faults, improving overall uptime and safety.
