FAQs
The 74B-3 is a cylindrical, non-indicating fuse rated for 60 V DC and 3 A. It fits standard Bussmann/74-series fuse blocks and holders, with dimensions of 1.62 in length, 0.42 in width, and 2.4 in height. Use in clean, upright mounting to avoid vibration-related wear and ensure easy access for replacement.
Yes. The 74B-3’s compact cylindrical form and 60 V DC, 3 A rating make it ideal for telecom cabinets, control panels, and rack-mounted equipment. Its non-indicating design reduces visual clutter, aiding quick verification during maintenance while providing reliable overcurrent protection for sensitive telecom components.
This fuse is CE Marked, meeting European safety and environmental compliance expectations. While other certifications are not listed for this specific part, CE marking supports regulatory alignment for installations across European markets and service contracts.
Fast-acting fuses respond quickly to overcurrent events, cutting fault currents before fault energy damages sensitive telecom electronics. This reduces arc exposure, minimizes downtime, and protects power supplies and data interfaces — crucial for high-availability telecom networks or data-centre applications.
By delivering reliable, fast-acting protection in a compact form factor, the 74B-3 lowers the risk of unexpected equipment failures and nuisance trips. The standard dimensions and CE compliance support easy replacements and multi-site deployments, reducing maintenance time and inventory complexity.
