Eaton KAB-20 Tron High Speed Fuse - 20 A Rating
Part Number: KAB-20
Quick Summary
KAB-20 Tron high speed fuse protects rectifier and DC power circuits in industrial systems. Engineers often wrestle with nuisance outages caused by undersized or slow-acting protection devices, leading to unplanned downtime. In practice, industry standards emphasize CE marking, IP enclosure protection, and safety integrity level considerations when selecting protective fuses. The KAB-20 offers a compact 20 A fast-acting solution with a predictable interrupt profile, helping minimize collateral damage during faults. Its small footprint and widely used catalog number streamline stocking and field swaps, while continuing to support cost efficiency and maintenance planning.

KAB-20~TRON RECTIFIER FUSE
Eaton Specification Sheet - KAB-20
Datasheet - FNQ-30
KAB-20's high-speed fuse action delivers rapid current interruption during short circuits, reducing equipment damage and downtime. This translates to safer startups and fewer production interruptions in critical processes, such as rectifier power stages and industrial DC circuits. The fuse's compact 0.5 in width and 0.5 in depth, with a height of 1.98 in, enables tighter panel layouts and easier retrofits in existing control enclosures, minimizing rework costs without compromising protection. The 20 A rating provides reliable protection for medium-current RMS demands, supporting longer equipment life and fewer nuisance trips in drive and power-supply applications. With a weight of 0.4 lb, the part adds minimal load to panel assemblies, aiding in multi-channel protection schemes. The catalog number KAB-20 and standard UPC/EAN references simplify procurement and inventory management across global sites. Documentation, including datasheets and catalogs, is readily accessible to streamline installation and maintenance planning. Compliances indicate that confirmation with the factory is advised to ensure site-specific regulatory alignment. The combination of protection performance and supply-chain simplicity makes KAB-20 a practical choice for industrial protection strategies.

FAQs
The KAB-20 is best suited for protecting rectifier power stages and DC power circuits in industrial control systems. With a 20 A rating and a compact footprint, it supports fast-acting protection in tight panel enclosures, reducing the risk of damage from short circuits while enabling straightforward replacement in standard fuse holders.
By delivering rapid interruption during overcurrent events, the KAB-20 minimizes fault duration and collateral damage to power electronics. Its compact size simplifies installation and reduces panel space occupancy, enabling easier maintenance and quicker swaps in multi-channel DC power supplies, which translates to reduced downtime and higher overall equipment effectiveness.
Compliance for the KAB-20 should be confirmed with the manufacturer, as indicated in the product data. While industry-standard considerations like CE marking and IP protection are typical for electrical protection devices, always verify the specific certifications and regulatory approvals applicable to your region and application with Eaton to ensure site-specific compliance.
Official KAB-20 documentation is available through Eaton’s catalogs and specifications pages. Key resources include the KAB-20 Tron Rectifier Fuse catalog, the Eaton Specification Sheet for KAB-20, and technical bulletins. Accessing these documents helps verify electrical ratings, dimensions, and installation guidelines for proper field use.
The KAB-20 provides a predictable 20 A protection profile in a compact 0.5x0.5x1.98 in package with a 0.4 lb weight, simplifying stocking and field replacements. This reduces spare-part diversity, shortens maintenance cycles, and lowers total cost of ownership by improving mean time between failures and minimizing downtime in critical industrial applications.
