Eaton 24B-4 Telecommunication Fuse - 60 VDC, 4 A
Part Number: 24B-4
Quick Summary
Eaton Bussmann Type 24 telecommunication fuse protects critical DC telecom circuits in rack-mounted gear. In dense layouts, improper protection or bulky components can cause downtime and maintenance delays. Note that CE marking, RoHS compliance, and SIL safety certifications are commonly required in telecom deployments; verify exact scope in Eaton's datasheets. The 24B-4 delivers a compact 1.46 inch length, 0.375 inch height, flat yellow, non-indicating design to maximize panel density and simplify part replacement. Using this Bussmann series fuse supports streamlined procurement and predictable performance, translating to faster field service and reduced total cost of ownership. Its 60 V DC, 4 A rating aligns with typical telecom power rails, making it a practical choice for network edge devices and data-center infrastructure.

Eaton Specification Sheet - 24B-4
Feature: Flat fuse style delivers a slim, space-saving profile that enhances panel density in telecom cabinets. Benefit: Enables higher packing density without sacrificing protection, reducing enclosure depth and easing wiring layouts. Application: Ideal for compact network switches, edge routers, and DC power rails in data centers. This translates to measurable efficiency gains during installation and service. Feature: 60 V DC, 4 A electrical rating ensures appropriate protection for low-voltage telecom circuits. Benefit: Limits fault current without nuisance trips, preserving equipment uptime and extending component life. Application: Suitable for DC bus protection on telecom and networking hardware where stable, predictable protection is critical. Industry practitioners report lower maintenance costs when correct ampere ratings are chosen for DC rails. Feature: Flat fuse with yellow color code supports quick visual identification. Benefit: Speeds maintenance and fuse replacement in complex cabinets, reducing downtime and human error. Application: Field service in telecom racks where fast part recognition improves mean time to repair. Feature: Non-indicating fuse design minimizes failure modes and avoids false indicators in busy environments. Benefit: Reduces false alarms and diagnostic complexity, improving overall reliability. Application: Systems with external monitoring rely on electrical protection rather than indicator lamps. Feature: Catalog number 24B-4 and Bussmann series compatibility simplify procurement and stocking. Benefit: Streamlines purchasing workflows and spare-part management. Application: Procurement teams in data centers and telecom installers benefit from consistent sourcing. Feature: Specific dimensions 1.46 in length, 0.375 in height, 0.001 in width, and weight 0.2 lb enable easy integration in space-constrained enclosures. Benefit: Facilitates plug-and-play replacement and standardized enclosure design. Application: OEM equipment and retrofit projects where enclosure form-factor matters.

FAQs
The 24B-4 is a compact, flat fuse designed for telecom panels. Plan for its 1.46 in length and 0.375 in height to fit tight spaces, using standard Bussmann series holders. Its non-indicating design means status monitoring should come from system diagnostics rather than a visual fuse indicator. Use the catalog number 24B-4 to source compatible holders and spares.
The 24B-4 provides a 60 V DC rating and 4 A current rating, suitable for DC telecom circuits. It is a flat fuse with a yellow color code and non-indicating feature, which supports clear identification in assemblies without additional indicators. This combination protects equipment while maintaining compact panel layouts.
Yes. Designed for DC power rails up to 60 V, the 24B-4 protects telecom and data-center networking gear from overcurrent conditions. Its compact form factor and Bussmann series compatibility simplify deployment in dense cabinets and OEM equipment, helping maintain uptime and reduce spare-part complexity.
The product data does not list specific certifications; when selecting for regulated environments, verify CE marking, RoHS compliance, and applicable safety certifications (such as SIL) in the official Eaton specifications. Always consult the Eaton datasheet for the exact standards applicable to your region and application.
The 24B-4’s compact footprint lowers panel footprint and supports higher-density assemblies, reducing installation time and space costs. Non-indicating operation means you’ll rely on diagnostics rather than visual checks, which can streamline maintenance workflows when paired with proper monitoring. Steady supplier availability (Bussmann series) also helps minimize downtime due to part shortages.
