Eaton BK/KTK-R-5 Fuse - Class CC Fast-acting, 600 V
Part Number: BK/KTK-R-5
Quick Summary
The Eaton BK/KTK-R-5 fuse provides fast-acting overcurrent protection for branch circuits and industrial control panels. When nuisance trips or slow replacements threaten uptime, engineers need a reliable, readily stocked option that fits common Bussmann form factors. This device carries CE Marked and RoHS Compliant certifications, and offers a 200 kAIC interrupt rating with a 600 V rating for demanding electrical environments. Bulk packaging and compatibility with isolated, in-line fuse holders simplify procurement and panel design, delivering measurable business value. The compact 1.5 in length and 0.41 in width/height support dense layouts while maintaining robust protection across industrial applications.

Eaton Specification Sheet - BK/KTK-R-5
Feature LIMITRON fast-acting design delivers rapid fault interruption, reducing equipment damage and unexpected downtime, with a 5 A rating suitable for controlled branch circuits and industrial control points. Business impact: improved shutdown safety and reduced service costs; application: protect motor controls and PLC power feeds in compact control panels. Feature Rejection style ensures proper fuse holder compatibility and reduces mis-placement during maintenance, delivering faster replacements and lower field error rates. Business impact: streamlined maintenance and lower inventory mis-picks; application: street lighting and outdoor control panels with isolated holders. Feature Class CC and 600 V rating provide standardized protection across a broad range of equipment; business impact: regulatory alignment and cross-application resilience. Application: bulk-stocked, standards-compliant protection for industrial facilities seeking reliable in-line protection solutions. Feature Non-indicating indicator lowers cost and simplifies compliance testing, while the bulk packaging type reduces procurement cycles and warehousing effort. Application: high-volume projects needing repeatable, quick-order fulfillment in electrical protection catalogs. Feature 200 kAIC interrupt rating delivers strong short-circuit tolerance for locations with high fault currents; business impact: enhanced system reliability and reduced collateral damage. Application: feeders and branch circuits in large industrial plants.

FAQs
Install the BK/KTK-R-5 into a compatible Bussmann in-line fuse holder designed for Class CC fuses. Ensure the holder matches the 1.5 inch length and 0.41 inch width/height footprint. Confirm a 600 V system rating and secure electrical connections before power-up. This configuration minimizes mis-insertion and supports quick maintenance with bulk stock availability.
Key ratings are 5 A amperage, Class CC, 600 V voltage rating, and a 200 kAIC interrupt rating. These specs ensure fast-acting protection for branch circuits and industrial control equipment while tolerating high fault currents without nuisance trips in typical or clean-room environments.
Yes. The fuse is designed for street lighting applications (isolated, in-line fuse holders) and other specialized circuits. The 600 V rating and high interrupt capability make it suitable for outdoor or exposed environments when paired with appropriate enclosures and protection accessories.
The BK/KTK-R-5 carries CE Marked and RoHS Compliant certifications, meeting European regulatory requirements and restricting hazardous materials. This helps ensure compliance across markets and streamlines procurement for regulated electrical installations while supporting sustainable manufacturing practices.
Bulk packaging reduces reorder frequency and procurement lead times, lowering administrative overhead and stockouts. The non-indicating design minimizes implementation costs, while compatibility with standard Bussmann series holders reduces panel redesign time, delivering faster project completion and lower maintenance costs over the fuse’s lifecycle.
