KTK-2-1/2~KTK-2-1-2~LIMITRON FAST ACTING FUSE
The KTK-2-1/2 fuse offers a small footprint that frees precious panel space, enabling more compact control cabinets and easier wiring runs. The 2.5 A amperage rating paired with a 600 V maximum rating provides precise protection for low-current control circuits without nuisance trips, improving overall equipment uptime. A 100 kAIC interrupt capability ensures fast and reliable fault clearance in mains-connected applications, enhancing safety and reducing downstream damage. Ferrule-end x ferrule-end terminations simplify installation and replacement within standard fuse blocks, while the melamine tube and nickel-plated bronze endcaps deliver robust thermal and mechanical performance in harsh industrial settings. Non-indicating design keeps costs down, though external status indicators can be added where fault visibility is required. The fuse’s RoHS and CE compliance supports global deployment and regulatory alignment, and its compact form-factor supports flexible cabinet layouts and efficient maintenance planning. In short, it combines regulatory readiness, space efficiency, and dependable protection for industrial automation and electrical protection and circuit control needs.

FAQs
KTK-2-1/2 is designed for control circuits, lighting circuits, and meter circuits inside industrial panels where space is at a premium. It uses ferrule-end terminations and a compact body, delivering reliable fast-acting protection without crowding the enclosure. Ideal for compact automation cabinets, it supports efficient wiring, straightforward replacement, and predictable performance in harsh industrial environments.
Key ratings include a 2.5 A amperage rating, 600 V voltage rating, and 100 kAIC interrupt rating, enabling safe interruption of fault currents in control and power circuits. The fuse is non-indicating, which reduces panel wear and costs, while the melamine tube and nickel-plated bronze endcaps provide robust mechanical and thermal performance for long service life.
Yes. The KTK-2-1/2 is RoHS compliant and CE marked, aligning with European regulatory requirements and restricted substances standards. This simplifies global deployment for machine builders and integrators, ensuring your control panels meet current environmental and safety directives, and supports compatibility with international product standards.
The fuse is compact, with a body length and width of 0.41 in and a height of 1.5 in, weighing about 0.19 lb. This small footprint frees space in crowded control panels and enables easier routing of control wiring, while ferrule-end construction simplifies installation in standard fuse blocks and reduces mounting complexity.
Non-indicating fuses rely on external status indicators or system fault monitoring. For maintenance, plan periodic checks of external indicators or integrate with a panel-level status circuit. The fast-acting LIMITRON design provides predictable trip behavior, and replacement is straightforward due to ferrule-terminal design and a standard form factor that fits common Bussmann-style fuse blocks.
