KTK-3-1/2~KTK-3-1-2~LIMITRON FAST ACTING FUSE
The KTK-3-1/2 fuse showcases a small footprint that frees panel space while maintaining secure ferrule-end connections, enabling faster installation and cleaner wiring, which translates to reduced assembly time and improved reliability in dense control cabinets. With a 3.5 A rating and 600 V voltage rating, it protects control circuits, lighting, and meter connections without overfusing, lowering maintenance costs and unexpected downtime in critical equipment. The 100 kAIC interrupt rating at 600 V provides high fault-current resilience, offering peace of mind in applications with potential short-circuit transients. Its nickel-plated bronze endcaps and melamine tube deliver rugged durability in industrial environments, extending service life in dusty or humid plant floors. CE and RoHS compliance simplify EU procurement and regulatory adherence, while the small footprint and standard ferrule terminations support easy retrofit and scalable installations. This fuse is a strong fit for European and North American panels seeking reliable, space-efficient protection without complex installation steps.

FAQs
Install the KTK-3-1/2 by aligning the ferrule ends with a compatible fuse holder, press firmly until seated, and verify full engagement for secure electrical contact. Ensure the power is de-energized before work. Use standard panel procedures for wiring and torque checks, and confirm the assembly matches the Bussmann series end-cap dimensions for reliable operation in 600 V systems.
The KTK-3-1/2 is a 3.5 A fast-acting fuse rated for 600 V with a 100 kAIC interrupt rating at 600 V. It uses ferrule-end terminations and a melamine tube with nickel-plated bronze endcaps, offering robust circuit protection for control circuits, lighting, and meter circuits while meeting CE and RoHS compliance requirements.
Yes. Its CE marking and RoHS compliance align with European and many global design standards, while the 600 V rating covers common US industrial applications. The small footprint and ferrule-end connections simplify integration into compact control cabinets and standard Bussmann series catalog builds, supporting scalable, cross-region procurement without redesign.
CE marking confirms conformity with European safety, health, and environmental requirements, while RoHS compliance ensures restricted use of hazardous substances. These certifications matter because they streamline regulatory approvals, facilitate EU-based project deployment, and support compliance-driven procurement for multinational equipment and systems that demand traceable, safe components.
The fuse’s small footprint enables denser, more reliable panel layouts, reducing enclosure size and wiring complexity. Its rugged construction with nickel-plated endcaps and melamine tube withstands industrial conditions, decreasing replacement frequency. The high interrupt rating protects critical equipment against faults, lowering downtime and service costs across control and lighting installations.
