FAQs

KTK-R-9 uses ferrule end connections and a Class CC form factor, making it compatible with standard industrial control panels, lighting panels, and machinery panels that use Bussmann Series fuse geometries. It fits common DIN-rail or chassis-based layouts when paired with appropriate ferrule-terminals, enabling straightforward retrofits and new builds.
The KTK-R-9 is a 9 A current-limiting, fast-acting fuse rated for 600 V and provides an interrupt rating of 200 kAIC. This combination supports protection for medium-current control circuits, capacitors, and distribution networks while maintaining fast fault clearance in high-energy environments.
Yes. The KTK-R-9 is UL Listed and CSA Certified, with CE Marking and RoHS compliance. This combination ensures regulatory acceptance in many regions, simplifies qualification processes, and supports environmentally responsible manufacturing and end-use.
Ideal for industrial controls panels, street lighting, general lighting, capacitors, and distribution circuits. Its dual-element design and high interrupt rating make it suitable for protecting power supplies, motor control centers, and other critical infrastructure while helping keep downtime to a minimum.
The KTK-R-9 offers predictable protection curves, reduced nuisance trips, and secure ferrule-term connections that speed up installation and maintenance. With UL/CSA/CE marks, it minimizes qualification risk, supports standard spare stocking (packaging of 10), and lowers total cost of ownership through longer mean time between failures and simpler procurement.
