Eaton TPN-6 Telecommunication Fuse - 100 kAIC / 170 Vdc
Part Number: TPN-6
Quick Summary
The Eaton TPN-6 telecommunication fuse provides reliable overcurrent protection for telecom power rails and line cards. In dense racks and remote sites, nuisance trips or undersized interrupts drive costly downtime. Key specs include a 100 kAIC interrupt rating and 170 Vdc rating, with current-limiting action and silver-plated terminals. Certification status varies by region, so consult the Eaton datasheet for CE, UL/CSA, and other approvals applicable to your installation. This fuse supports reliable telecom protection with a compact form factor, straightforward installation, and predictable lifecycle costs, making it a solid choice for mission-critical networks. Its non-indicating design minimizes maintenance overhead in the field.

FAQs
TPN-6 is designed for Bussmann series fuse holders and standard telecom panels. With its compact dimensions (0.56 in W x 0.56 in D x 2 in H) and standard packaging, it fits dense rack environments and retrofits into existing fault-protection schemes without extensive enclosure changes. Ensure the holder and connectors match the silver-plated terminals for optimal contact performance.
The TPN-6 fuse provides a 6 A amperage rating, a 170 Vdc voltage rating, and a 100 kAIC interrupt rating. It is current-limiting, non-indicating, and features silver-plated terminals to maintain low contact resistance. These ratings make it suitable for protecting telecom DC power rails and line cards against high-energy faults.
Yes. The 170 Vdc voltage rating and 100 kAIC interrupt capacity are tailored for DC telecom environments, providing rapid fault interruption while protecting downstream components. It is well-suited for telecom power rails, line cards, and DC distribution modules where reliable protection and minimal downtime are essential.
Certification status can vary by region. For exact approvals such as CE, UL/CSA, and other region-specific certifications, refer to the Eaton TPN-6 datasheet and supplier documentation. Always verify the latest certifications with your procurement team before deploying in regulated environments.
The non-indicating design reduces field maintenance checks, while its current-limiting operation minimizes arc energy and protects downstream components, leading to less downtime and fewer component replacements. In addition, its compact form factor simplifies installation in tight telecom cabinets, contributing to lower installation costs and faster recovery in fault events.
