FAQs
The KAB-4 should be installed in a fuse holder or block rated for small-form protection and compatible with a 4 A fast-acting device. Use proper torque on terminals, ensure adequate clearance for heat dissipation, and align with panel layout to minimize wiring complexity. Reference the catalog number for procurement and datasheets for mounting guidelines.
Key specs include a 4 A amperage rating, compact dimensions (0.5 in length and width, 1.98 in height), and a weight of 0.4 lb. Catalog number is KAB-4, with UPC 051712460040 and EAN 5027590098113. It is described as a high-speed rectifier fuse suitable for protecting power electronics in automation applications.
Yes. The 4 A high-speed rating and Tron family design make the KAB-4 well-suited for rectifier power supplies and motor drives where fast interruption minimizes semiconductor damage and downtime. Ensure the surrounding circuitry and heat management are appropriate for continuous operation and that the fuse holder supports the small form factor.
The product data shows compliances as 'Contact factory / Contact Manufacturer,' so region-specific certifications may vary. To verify CE, UL, IP ratings, or other approvals for your market, contact Eaton directly or request documented certification within the datasheet package. Always confirm current compliance before installation in regulated environments.
The KAB-4 provides fast overcurrent protection, reducing semiconductor damage and downtime, which lowers repair costs and machine downtime. Its compact form factor simplifies panel design, reduces inventory complexity through a common catalog entry (KAB-4), and enhances serviceability in routine maintenance, contributing to lower total cost of ownership over time.
