Eaton KTK-6 Fuse - 6A, 600V, 100kAIC, CE RoHS
Part Number: KTK-6
Quick Summary
KTK-6 fuse by Eaton Bussmann provides fast-acting protection for control circuits and lighting networks in industrial panels. Engineers frequently contend with nuisance trips and downtime when fuses are mismatched to load profiles; this device delivers a precise 6 A rating for reliable circuit protection. It carries CE marking and RoHS compliance, supporting regulatory acceptance, and it operates at up to 600 V with a 100 kAIC interrupt rating for high-energy applications. With ferrule-end connections, a melamine tube, and nickel-plated endcaps, it installs quickly in standard assemblies, reducing commissioning time. Its compact 0.41 in width and 1.5 in height fit space-constrained panels, offering lower lifecycle costs and improved uptime.

KTK-6~LIMITRON FAST ACTING FUSE
Datasheet - FNQ-30
The KTK-6 fuse uses a 6 A, fast-acting design to interrupt fault currents quickly with minimal arcing, protecting sensitive control circuits and meters. This precise protection translates to reduced downtime, safer operation of drives and instrumentation, and fewer unwarranted replacements in busy control cabinets. It is rated for 600 V with a 100 kAIC interrupt capability, enabling reliable protection in medium-energy installations and large lighting circuits while maintaining system integrity. Ferrule-end x ferrule-end connections and a non-indicating design simplify installation and replacement in crowded enclosures, accelerating commissioning and minimizing panel downtime. The melamine tube with nickel-plated bronze endcaps delivers robust mechanical performance, resisting vibration and temperature swings common in industrial environments, extending service life. CE marking and RoHS compliance align with global regulatory expectations, supporting cross-border deployments and supplier audits. The fuse’s compact footprint (0.41 in wide, 1.5 in high) fits modern, space-constrained panels, enabling scalable protection across multiple boards without adding bulk. As part of the Bussmann series, it ensures compatibility with existing catalogs and common interchanges, reducing spare-part variety and simplifying procurement.

FAQs
The KTK-6 is designed for control circuits, lighting circuits, and meter interfaces in industrial panels. With a 6 A rating and 600 V operating range, it provides reliable protection for automated equipment, PLCs, and instrumentation while fitting into compact Bussmann series layouts. Its ferrule-end construction makes replacement straightforward in standard panel assemblies.
Install using ferrule-end terminals to ensure a secure, vibration-resistant connection. The fuse’s non-indicating, compact design (0.41 in x 0.41 in x 1.5 in) fits tight spaces, and the nickel-plated endcaps simplify insertion and removal. Always verify load ratings and verify the 6 A rating matches the protected circuit to avoid nuisance trips.
KTK-6 is specified for 600 V systems with an interrupt rating of 100 kAIC at 600 Vac, indicating primary use in AC circuits. For DC applications, consult the datasheet to confirm any DC-specific ratings or deratings before deployment in DC-powered equipment.
The KTK-6 carries CE marking and RoHS compliance, supporting regulatory acceptance in many markets. These certifications help with safety and environmental requirements during audits and in global manufacturing environments.
The KTK-6 offers predictable protection with a compact footprint, reducing panel space and spare-part diversity. Its robust construction (melamine tube, nickel-plated endcaps) and high interrupt rating help minimize downtime from faults, lowering maintenance costs over the device’s lifecycle and improving overall equipment reliability in automation and electrical protection schemes.
