FAQs
KTK-3 uses ferrule end x ferrule end terminations and measures 1.5 in long with 0.41 in width/height, matching standard ferrule crimps found in control panels. To ensure compatibility, select ferrules sized for 3 A protection and verify the panel cutout and lead length align with the device dimensions. This minimizes installation time and wiring errors while preserving a tidy enclosure.
KTK-3 is a 3 A fuse rated for 600 V, with a 100 kAIC interrupt rating at 600 V. It is designed for control circuits, lighting circuits, and meter circuits in industrial environments. Its compact form and ferrule-end connections support quick replacement in panel boards and electrical cabinets, delivering safe, reliable circuit protection with minimal footprint.
Yes. The KTK-3 is a LIMITRON fast-acting fuse suitable for control circuits, lighting, and metering in industrial automation. Its 3 A rating and 100 kAIC interrupt capability protect sensors, PLC I/O, and protective relays while its small footprint keeps panel density low. The non-indicating design aids quick visual checks without misreads in busy control cabinets.
The KTK-3 is CE marked and RoHS compliant, ensuring compliance with European regulatory standards and reduced hazardous substances. These certifications support global product acceptance, supplier qualification, and adherence to industry safety requirements, which is crucial for projects requiring formal conformity documentation and international procurement.
The KTK-3’s compact ferrule-end design and non-indicating construction simplify replacement and reduce diagnostic ambiguity in dense panels, lowering maintenance time. Its high interrupt rating minimizes downtime during fault events, while the rugged nickel-plated endcaps and melamine tube contribute to long service life, delivering lower total cost of ownership across panel installations.
