KTK-1-1/2~KTK-1-1-2~LIMITRON FAST ACTING FUSE
Feature: 100 kAIC interrupt rating at 600 V. This level of fault current handling protects equipment in automation panels, reducing the risk of extended downtime during electrical faults. By clearing faults quickly, the KTK-1-1/2 helps maintain process continuity in control circuits and meter applications. Feature: 1.5 A amperage rating with a non-indicating design. This pairing offers precise protection for sensitive control circuits without an LED or window that can muddy panel aesthetics. The absence of an indicator reduces maintenance and cost while improving reliability in tight enclosures. Feature: Ferrule end x ferrule end termination. This termination style enables fast, repeatable installations in standard fuse holders and minimizes stray resistance at terminations. It supports reliable connections in compact control panels controlling lighting circuits and meters. Feature: Nickel-plated bronze endcaps and melamine tube construction. This combination provides durable end connections and temperature resistance for industrial environments, minimizing debris intrusion and maintaining consistent performance across temperature variations. Feature: Small footprint and standard packaging. The compact 0.41 in length and 0.41 in width footprint allows denser panel layouts and easier retrofits. Standard packaging supports straightforward stocking and faster project onboarding. Feature: Compliance and datasheet availability. CE Marked RoHS Compliant certification ensures global market access, while Eaton's specification sheets and data sheets support engineering validation. The fusion of form factor, rating, and global compliance translates to lower procurement risk and faster time-to-value.

FAQs
Install the KTK-1-1/2 fuse in a standard ferrule-end fuse holder designed for Bussmann devices. Ensure the ferrule ends engage fully with clean, level contacts and tighten to the holder’s recommended torque. Because the fuse is non-indicating, verify circuit status via panel tests after replacement. Use properly crimped ferrules to avoid loose connections and intermittent faults. This installation approach minimizes contact resistance and preserves panel reliability in automation and control applications.
Key specifications include an amperage rating of 1.5 A, a voltage rating of 600 V, and an interrupt rating of 100 kAIC at 600 VAC. It uses ferrule-end terminations and a melamine tube with nickel-plated bronze endcaps. The fuse is non-indicating and is intended for control circuits, lighting protection, and meter circuits in industrial settings.
Yes. The KTK-1-1/2 is designed for control circuits, lighting circuit protection, and meter circuits within automation and process control environments. Its compact footprint, 1.5 A rating, and high interrupt capacity enable reliable protection without occupying valuable panel space, making it a practical choice for OEMs and panel builders working with space-constrained enclosures.
The KTK-1-1/2 fuse carries CE Marking and RoHS compliance, reflecting adherence to key European regulatory requirements and environmental standards. These certifications support global deployment and product reliability in regulated industries such as manufacturing, building automation, and infrastructure projects.
The fuse features a compact footprint with product length/depth of 0.41 in, product width of 0.41 in, and product height of 1.5 in. It weighs approximately 0.19 lb. This small form factor enables dense panel layouts and easier retrofits in control panels and meter assemblies.
