Eaton BK/KTK-R-3 Fuse - Class CC, 3 A, 200 kAIC
Part Number: BK/KTK-R-3
Quick Summary
The Eaton Bussmann BK/KTK-R-3 fuse delivers fast-acting protection for branch circuits and industrial control panels. Engineers often struggle with nuisance trips and selecting fuses that reliably interrupt faults without degrading service. This device is RoHS compliant and CE marked, with a 200 kAIC interrupt rating at 600 V, and it uses a rejection-style design. These features support compliant, reliable protection in bulk procurement for control panels, street lighting, and specialized circuits, while keeping installation straightforward. Users benefit from a compact form factor, standard bulk packaging, and clear compatibility with isolated or in-line fuse holders in industrial environments. By combining 3 A fast-acting protection with a robust 600 V rating and a 200 kAIC interrupt capacity, this fuse reduces downtime and extends equipment life.

Eaton Specification Sheet - BK/KTK-R-3
Designed as a LIMITRON fast-acting fuse, the BK/KTK-R-3 provides precise current limiting for circuits that demand fast fault interruption. The 3 A rating paired with Class CC construction yields repeatable blow characteristics, protecting small feeders and industrial control loops without sacrificing selectivity. In practice, this means fewer nuisance trips on startup surges and a quicker return to service after a fault, improving overall line uptime in automation panels and compact control enclosures. Rejection-style design helps prevent incorrect fuses from being installed in crowded panels, supporting safer, faster maintenance and accurate protection coordination. With a 600 V rating and 200 kAIC interrupt capability, BK/KTK-R-3 can safely interrupt high-energy faults typical of motors and street-lighting applications, reducing thermal and mechanical stress on downstream equipment and wiring. The fuse is non-indicating, which lowers cost while still providing robust protection when used with appropriate holders; its compatibility with isolated or inline fuse holders enhances serviceability in retrofit and new builds alike. Bulk packaging listed under catalog notes simplifies procurement for large projects and repair stocks, reducing administrative overhead and inventory fragmentation. RoHS compliance and CE marking meet global regulatory expectations, easing cross-border installation and supplier qualification. The fuse is non-indicating, which lowers cost while still providing robust protection when used with appropriate holders; its compatibility with isolated or inline fuse holders enhances serviceability in retrofit and new builds alike. Compact dimensions—1.5 in length and 0.41 in both width and height—allow easy integration into compact control panels, junction boxes, and backplane assemblies. The standard Bussmann series form factor supports straightforward replacement and maintenance outsourcing, while the bulk catalog notes ensure consistent availability across sites. In addition, the non-indicating fuse indicator reduces unnecessary visual checks during routine inspections.

FAQs
Install BK/KTK-R-3 into a compatible isolated or inline fuse holder rated for 600 V. Verify the surrounding wiring matches the 3 A rating and is sized for fault current. Use standard Bussmann series holders and confirm the fuse sits securely to prevent micro-arcing. The bulk packaging simplifies stocking for maintenance schedules.
A 200 kAIC interrupt rating indicates the fuse can interrupt up to 200 kA symmetrical fault current at its rated voltage. This provides protection against high-energy faults in industrial circuits, reducing damage to downstream equipment and maintaining safe shutdown in panels and motor control applications.
Yes. The BK/KTK-R-3 is listed for street lighting applications, including isolated or inline fuse holders. Its 600 V rating and 200 kAIC interrupt capacity support reliable protection for lighting feeders while maintaining service continuity during faults.
The BK/KTK-R-3 carries RoHS compliance and CE marking, meeting global environmental and safety standards. Bulk packaging facilitates procurement for large projects, while the non-indicating design keeps field maintenance simple when used with compatible holders.
Using a fast-acting 3 A fuse with a high interrupt rating minimizes downtime by rapidly isolating faults, reducing downtime and wear on protective devices. Bulk packaging lowers procurement time, and RoHS/CE compliance reduces regulatory hurdles in multinational facilities, delivering predictable maintenance cycles and lower total cost of ownership.
