Eaton BK/KTK-20 Fuse - Class CC, 200 kAIC
Part Number: BK/KTK-20
Quick Summary
The Eaton Bussmann series KTK fuse provides reliable 20 A overcurrent protection for control circuits, lighting, and meter feeds. In compact control panels, selecting a fuse that fits the available space while delivering predictable interruption is a frequent challenge. With a 200 kAIC interrupt rating and a 600 V rating, this fuse safeguards equipment against high fault currents without nuisance trips. CE Marked and RoHS compliant, it meets modern regulatory requirements for industrial machinery. Bulk packaging and a Class CC design support efficient stocking and quick replacements, while a non-indicating end-face keeps panel aesthetics and maintenance simple. The BK/KTK-20 blends proven protection with installation convenience, helping OEMs minimize downtime and total cost of ownership.

Eaton Specification Sheet - BK/KTK-20
20 A amperage rating delivers precise protection for low-to-moderate load circuits in control panels, reducing the risk of nuisance trips while preserving downstream equipment. This translates to fewer unexplained outages during startup and smoother operation of automation modules in manufacturing lines. The 200 kAIC interrupt rating provides robust protection against high fault currents, enabling safe isolation of faults in power-distribution networks and reducing risk of collateral damage to adjacent equipment. The 600 V voltage rating ensures compatibility with common industrial power systems, supporting reliable operation across multiple machines in automated lines. Class CC, non-indicating design with a rejection feature minimizes mis-insertion and simplifies panel maintenance, while nickel-plated bronze endcaps and a melamine tube offer durable, corrosion-resistant construction for harsh environments. Bulk packaging supports efficient inventory management and fast replacements in high-volume assembly and service operations.

FAQs
When installing BK/KTK-20, ensure the fuse holder is rated for Class CC devices and matches the 20 A rating. Use identical catalog specifications and verify correct orientation of the endcaps. Because of its non-indicating design, rely on panel wiring diagrams and upstream protection coordination to confirm operation after replacement.
A 200 kAIC interrupt rating indicates the fuse can safely interrupt extremely high fault currents without arcing or fuse damage, protecting downstream components and preventing collateral damage in high-energy systems. This rating is crucial for panels feeding motors, transformers, and power distribution blocks in industrial automation.
Yes. The BK/KTK-20 is designed for control circuits, lighting circuits, and meter circuits, offering 20 A protection at up to 600 V. Its Class CC form factor and bulk packaging streamline replacement in panelboards and switchgear found in manufacturing lines, data centers, and process control installations.
This fuse is CE marked and RoHS compliant, ensuring compliance with European regulatory requirements for electrical equipment and restricted hazardous substances. These certifications support global deployment, simplify procurement for international projects, and align with sustainability and safety standards in industrial automation.
The BK/KTK-20 contributes to ROI through reduced downtime from reliable fault interruption, lower maintenance costs due to bulk, easy-to-replace spares, and improved coordination with upstream protection. Its robust 200 kAIC rating and 600 V capability help protect critical control and lighting circuits, extending equipment life and reducing total cost of ownership.
