Special features
Ferrule design
Ferrule design enables secure, repeatable terminations that simplify field assembly and reduce installation time, delivering a measurable improvement in panel reliability and wiring clarity. The 3 A amperage rating within a Class K5 fuse family minimizes nuisance trips in low-current control circuits while preserving fast-acting protection for sensitive electronics. With a 10 kAIC interrupt rating and a 600 V voltage rating, the KOS3 delivers robust short-circuit protection in demanding automation applications, helping reduce unplanned downtime and safeguard equipment. Non-indicating status keeps panel layouts clean and free of visual indicators that could mislead technicians during maintenance. The Standard packaging type and a quantity of 10 per pack support efficient procurement and stocking, while the ferrule design supports consistent, vibration-tolerant connections across new builds and retrofits. Compatibility with Eaton Bussmann lineage and compliant CE marks enhances project reuse and regulatory alignment, even in constrained spaces.

FAQs
The KOS3 features a ferrule design intended for ferrule-type terminations commonly used in Bussmann/Eaton fuse assemblies. This ferrule-compatible interface simplifies field wiring, reduces loose connections, and supports consistent, repeatable terminations in control panels and machine enclosures, enabling faster installation and fewer remediation steps during maintenance.
The KOS3 is a 3 A fuse with a 600 V voltage rating and a 10 kAIC interrupt rating. This combination provides fast-acting protection for low-current control circuits while tolerating high fault currents, making it suitable for industrial control panels and machine circuits where reliable protection and quick fault isolation are required.
Yes, the KOS3 is designed for industrial protection needs such as control panels and automation equipment. It carries CE marking and CSA certification where applicable, aligning with safety and performance regulations in many regions. Always verify local compliance requirements and supplier documentation when integrating into a regulated system.
The KOS3 measures 5 inches in length with a cross-section of 0.81 by 0.81 inches and a weight of 0.001 lb. It is packaged in Standard packaging with a quantity of 10 units per pack, supporting straightforward stocking and distribution for batch orders and replenishment in manufacturing environments.
Using the KOS3 in a control panel upgrade provides predictable, compliant overcurrent protection with a compact ferrule design that eases wiring and reduces panel crowding. Its 3 A rating suits sensitive control electronics, while the 10 kAIC interrupt capacity minimizes downtime during faults. Compatibility with existing Eaton Bussmann components helps streamline procurement and maintenance planning.
