FAQs
The KTK-25 uses ferrule-end terminations on both ends, designed for standard ferrule wiring in electrical panels. It pairs with Eaton Bussmann KTK family holders and fits typical panel layouts, offering straightforward replacement and secure, repeatable connections in tight spaces thanks to its ferrule-end design and compact dimensions (0.41 in width/depth).
KT KTK-25 is rated for 25 A, 600 V, with an interrupt rating of 100 kAIC at 600 Vac. It is intended for control circuits, lighting circuits, and metering circuits in electrical panels, delivering controlled protection for critical loads while supporting safe clearance of faults in industrial environments.
Yes. The KTK-25 is designed as a compact Bussmann series fuse with non-indicating status, suitable for control and lighting circuits in industrial panels. Its small footprint and ferrule-end connections simplify installation in crowded switchgear, while the 25 A, 600 V rating covers common panel protection needs with reliable fault interruption.
The KTK-25 is RoHS compliant, aligning with material restrictions and environmental regulations. While its primary certifications are embedded in the Bussmann series design, the RoHS conformity supports regulatory requirements across many manufacturing regions and helps with sustainability and waste reduction in industrial deployments.
The KTK-25 offers long-term reliability with a non-indicating design that reduces maintenance checks while delivering consistent protection. Its robust 100 kAIC interrupt rating and 600 V capability minimize downtime from fault events, lowering total cost of ownership through fewer failed components, quicker replacements, and predictable panel performance.
