FAQs

Install the ferrule-end fuse into compatible Class CC socket blocks or holds within the panel, ensuring the ferrule ends engage fully. Verify a 1.5 A rating matches the circuit load, and consult the time-current curve for protection coordination. Replace only with an identical KTK-R-1-1/2 device to preserve the 200 kAIC interrupt rating and maintain non-indicating status.
Key specs include 1.5 A amperage rating, Class CC, dual-element current-limiting fast-acting design, 200 kAIC interrupt rating at 600 V, ferrule-end connections, and non-indicating indicators. It is CE Marked, RoHS Compliant, UL Listed, and CSA Certified.
Yes. The device is specified for street lighting and general lighting as part of its application set, offering reliable overcurrent protection for feeders and distribution in outdoor and semi-outdoor environments when paired with proper enclosure and installation practices.
The fuse carries UL Listed and CSA Certified certifications, along with CE marking and RoHS compliance, simplifying global procurement and fleet-wide regulatory alignment.
By using a fast-acting, current-limiting Class CC fuse with a high 200 kAIC rating, you reduce arc energy, minimize nuisance trips, shorten downtime, and simplify maintenance—yielding lower total cost of ownership across manufacturing and distribution deployments.
