FAQs
KTK-R-1/2 uses ferrule-end connections and a dual-element Class CC design, which simplifies field terminations and reduces wiring errors. Its 0.5 A rating and 600 V capability align with typical control circuits and distribution panels, while the 200 kAIC interrupt rating provides robust protection for sensitive relays, PLCs, and motor starters during fault events.
The fuse is current-limiting and fast-acting, rated at 0.5 A with a 600 V maximum, and a 200 kAIC interrupt rating. It features dual elements for reliable performance, a non-indicating indicator, and is designed for Class CC applications. Additional compatibility comes from RoHS compliance and UL Listed/CSA Certified status for safety and regulatory alignment.
Yes. The 0.5 A, 600 V rating with a 200 kAIC interrupt capacity makes it appropriate for street lighting circuits and capacitor banks where fast fault isolation and high surge tolerance are required. Its RoHS/CE/UL/CSA certifications support compliance in public installations and large lighting networks.
KTK-R-1/2 is UL Listed and CSA Certified, with RoHS compliance and CE marking. These certifications support regulatory acceptance, supplier qualification, and streamlined procurement for multi-region projects, easing the risk of non-conformance in manufacturing, utilities, and infrastructure deployments.
Opt for ferrule-end terminations to ensure solid, vibration-resistant connections. Use compatible panel layouts to optimize heat dissipation and prevent nuisance trips from transient faults. Reference the time-current curve from the datasheet to correctly coordinate with upstream devices, which reduces unnecessary replacements and improves overall uptime.
