Amperage Rating
5 A
The KAB-5 is a 5 A high-speed fuse designed to clear fast transients in rectifier circuits and power electronics. This rapid interruption minimizes damage to diodes, MOSFETs, and DC links, delivering measurable reductions in downtime and repair costs for automation equipment. In practice, it protects drives, switch-mode power supplies, and control panels where fast fault-clearing matters most. Its compact footprint—0.5 in by 0.5 in with a height of 1.98 in—facilitates dense panel layouts and easy replacement in retrofit projects. Engineers gain installation flexibility, as the small form factor fits standard Bussmann series holders and minimizes enclosure footprint without compromising protection. Rated at 5 A, the KAB-5 delivers precise protection aligned with typical rectifier and drive current profiles, helping to avoid nuisance trips during startup surges. This selective coordination supports longer component life and fewer field failures, translating to lower total cost of ownership for industrial automation systems. Comprehensive documentation, including catalogs and the Eaton specification sheet, enables fast sizing and compliant installation. With catalog references like KAB-5~TRON RECTIFIER FUSE, procurement teams can quickly verify compatibility with existing Bussmann components and standardised electrical protection strategies. From a reliability perspective, using a known-brand high-speed fuse in the Tron family supports maintenance planning and spare-part commonality across multiple lines. By aligning fuse selection with current demand and protection requirements, operators can optimize uptime, reduce risk, and improve overall equipment effectiveness in manufacturing environments.

FAQs
Yes. The KAB-5 is part of the Bussmann Tron line and is designed to fit standard Bussmann series fuse holders used in industrial control panels. Its compact 0.5 x 0.5 in footprint and 1.98 in height simplify mounting, while its catalog reference KAB-5 ensures quick cross-checking with existing panel designs and replacement parts. Always verify holder type and torque specifications during installation.
KAB-5 is rated at 5 A and classified as a high-speed (fast-acting) fuse. This means it interrupts quickly during overcurrent events, minimizing damage to rectifiers, diodes, and MOSFETs in power electronics. While exact clearing times depend on current overload factors, the device is designed to protect sensitive components in motor drives and power supplies with predictable, fast fault clearing.
Yes. The KAB-5 is well suited for rectifier circuits and drive electronics found in automation panels and industrial control systems. Its 5 A rating and fast-response behavior help prevent downstream damage from startup surges and short events, contributing to higher line reliability, reduced downtime, and easier maintenance planning in automation environments.
Compliances for this part are documented as 'Contact factory / Manufacturer' in the specification. Certification details such as CE, IP, or SIL may vary by region and lot. For exact certification status and regional approvals, consult Eaton's datasheets or contact Eaton directly to obtain the current certification records for KAB-5.
Choosing the KAB-5 supports reduced downtime due to fast fault clearing and predictable performance in rectifier circuits. Its compact size eases installation in dense panels, while official datasheets and catalogs streamline sizing and procurement. This alignment lowers spare-parts inventory and maintenance labor, delivering a favorable return on investment in high-uptime manufacturing environments.
