Eaton KTK-R-8 Fuse - Class CC, 200 kAIC, UL Listed
Part Number: KTK-R-8
Quick Summary
KTK-R-8 fuse is a current-limiting fast-acting device designed for protecting industrial controls panels and machinery. In harsh plant environments, nuisance trips and frequent part replacements drive downtime and operating costs. UL Listed and CSA Certified provide safety assurance, while CE marking and RoHS compliance support worldwide deployments. The rugged melamine tube construction and dual-element design improve surge handling and minimise collateral damage. Designed for industrial protection, these fuses integrate easily with Bussmann series accessories, improving panel reliability. They also enable faster maintenance and lower total cost of ownership, delivering measurable value for engineers and procurement teams. Its 8 A rating suits common protective schemes in control cabinets and lighting ballast circuits.

FAQs
KTK-R-8 installs like other Bussmann series Class CC fuses with ferrule-end terminations. Ensure the panel fuse holder is rated for 600 V and 8 A, and that ferrule-end conductors are properly crimped to the end caps. Maintain proper clearance and the time-current curve for selectivity and fuse coordination. This design supports straightforward replacement during maintenance, reducing downtime.
The KTK-R-8 is a current-limiting fast-acting fuse whose time-current characteristics are documented in Eaton’s datasheets. In motor drives and capacitive circuits, the fuse clears fast on short circuits yet tolerates temporary inrush, protecting downstream equipment without nuisance trips. Refer to the specific time-current curve to ensure coordination with upstream protections and drive protection schemes.
Yes. With an 8 A rating and 600 V capability, along with a high 200 kAIC interrupt rating, the KTK-R-8 suits lighting feeders, capacitors, and distribution paths in street and general lighting apps. Its dual-element design provides reliability against transient surges common in outdoor environments, while the ferrule-end connections support robust outdoor cabinet installations.
The KTK-R-8 is UL Listed, CSA Certified, CE Marked, and RoHS compliant. These certifications support global deployment by meeting safety, performance, and environmental standards across North America, Europe, and other regions. This reduces the regulatory burden during procurement and installation in multinational facilities.
The KTK-R-8 contributes to ROI through minimized downtime from fewer nuisance trips, reduced replacement costs due to higher fault tolerance, and easier maintenance thanks to non-indicating, rejection-style design. Its compact form and standard packaging also streamline procurement and assembly, lowering labor and inventory carrying costs over the asset life.
