Eaton 74H-4 Telecommunication fuse - CE Marked
Part Number: 74H-4
Quick Summary
Eaton 74H-4 Telecommunication fuse provides fast-acting overcurrent protection for telecom and data equipment. This compact cylindrical fuse helps engineers fit reliable protection into tight equipment bays while maintaining system integrity. While CE Marked compliance is listed, verify additional regional certifications (SIL, IP) in your specific application and environment. The Bussmann series lineage reinforces reliability, with a non-indicating fuse design that simplifies quick status checks during maintenance. This solution delivers a robust balance of protection, ease of sourcing, and compatibility with standard telecom assemblies, supporting uptime and regulatory compliance in industrial and building automation networks.

FAQs
Yes. The 74H-4 is a 60 V DC rated fuse designed for telecom and data equipment, providing fast-acting protection at 4 A. Ensure conductor sizing and enclosure fitment align with the cylindrical form factor and standard packaging, and verify any site-specific derating requirements per system design and manufacturer recommendations.
The 74H-4 fuse is rated at 4 A and 60 V DC. It is a fast-acting, cylindrical, non-indicating device suitable for protecting telecom circuits against overcurrent events. When selecting replacements, match both the amperage and the DC voltage rating to the protected path to maintain intended fault protection levels.
The 74H-4 is intended for telecom and data equipment protection within compact equipment racks and control cabinets. It fits standard Bussmann series configurations and supports cylindrical fuse applications where space is constrained. It is commonly deployed on power rails, interface boards, and short-run line circuits requiring reliable, quick interruption.
Yes, the 74H-4 carries CE Marked compliance, indicating conformity with EU safety, health, and environmental requirements for its intended use. This simplifies regulatory acceptance in Europe and other regions that recognize CE standards. For broader certifications such as SIL or IP, consult the official Eaton datasheet to confirm applicability to your installation.
The 74H-4 offers predictable fast-acting protection, reducing unplanned downtime and potentially lowering repair costs in telecom systems. Its non-indicating design requires periodic checks during servicing, but its compact cylindrical form and standard packaging simplify stock management and replacement lead times, improving MTTR and overall equipment uptime.
