KTK-3/4~KTK-3-4~LIMITRON FAST ACTING FUSE
Feature and benefit integration follows a practical pattern for industrial buyers. The 0.75 A amperage rating with a 600 V voltage rating and 100 kAIC interrupt capability ensures predictable fault clearance, reducing equipment damage and unplanned downtime in control panels. This translates to higher line availability for machines and faster service windows during maintenance. The ferrule end x ferrule end connection and nickel-plated bronze endcaps provide robust, vibration-resistant terminations, enabling quick field assembly in constrained spaces and lowering the risk of loose connections that trigger nuisance trips. The melamine tube adds dimensional stability and insulation performance, especially in environments with temperature cycling, contributing to longer fuse life. A non-indicating design minimizes component count while the small footprint saves valuable panel real estate, supporting modular vs. retrofit strategies. CE Marked and RoHS compliant status helps ensure regulatory alignment across multiple markets, reducing compliance-related delays in project procurement.

FAQs
Install the KTK-3/4 with ferrule-end terminations to ensure a secure, vibration-resistant connection. Use properly crimped ferrules and verify clearance to adjacent components. The nickel-plated bronze endcaps provide durable contact surfaces, reducing Resistance Over Time and improving long-term reliability in compact panels.
The fuse is rated for 0.75 A with a 600 V voltage rating and a 100 kAIC interrupt capability at 600 V. It is suitable for control circuits, lighting circuits, and meter circuits in industrial environments, where space constraints and quick fault clearance are critical considerations.
Yes. Its melamine tube and nickel-plated endcaps provide robust insulation and mechanical durability. The small footprint helps in tight panel layouts, and the 100 kAIC interrupt rating ensures reliable protection during short-circuit events, even in environments with higher transient stress.
The KTK-3/4 carries CE marking and RoHS compliance, signaling conformity with essential safety requirements and environmental directives. This reduces regulatory risk in multinational projects and simplifies sourcing for customers needing regulatory alignment across markets.
The fuse’s compact footprint, reliable fast-acting protection, and durable terminations can shorten assembly time, reduce downtime from nuisance trips, and lower wiring complexity in retrofits. Over the life of a panel, these factors translate to lower maintenance costs and improved equipment availability.
