Eaton TPM-4 Telecommunication Fuse - 80V CE Marked
Part Number: TPM-4
Quick Summary
The Eaton TPM-4 telecommunication fuse provides fast current-limiting protection for telecom and data-center power feeds. Design teams frequently struggle with compact fuses that still deliver robust short-circuit protection without nuisance trips in dense network gear. This device is CE Marked and offers a 20 kAIC interrupt rating in a miniature package, with an 80 Vdc rating suitable for telecom rails. Using TPM-4 helps maintain uptime, reduces risk of costly equipment damage, and simplifies procurement with standard packaging, making it a reliable choice for modern, space-constrained deployments in electrical protection & circuit control environments.

Eaton Specification Sheet - TPM-4
The TPM-4 combines an 80 Vdc voltage rating with a 4 A current rating, delivering reliable protection for 80 V telecom power rails while minimizing fault impact. Feature → Business Impact → Application: 80 Vdc rating protects sensitive telecom rails from overvoltage and transients, reducing equipment damage and downtime in data-center power distribution and line cards. The 20 kAIC interrupt rating provides robust fault handling, lowering risk of cascading failures in rack-mounted power systems and field deployments. Feature → Business Impact → Application: Current-limiting capability confines fault duration, shortening arc energy and enabling faster recovery, which translates to reduced maintenance costs and improved service availability in telecom offices and data centers. The non-indicating design minimizes maintenance checks in sealed enclosures, simplifying installation and reducing parts handling in field installs. Feature → Business Impact → Application: Miniature, standard-packaged form enables easy integration with common fuse blocks and chassis, accelerating deployment across new network infrastructure and retrofit projects. CE Marked compliance supports regulatory adoption across EU markets, easing supplier qualification and procurement, while the standard packaging type ensures compatibility with existing stock. In practice, these attributes support higher rack density, lower total cost of ownership, and improved return on investment for telecom protection circuits.

FAQs
TPM-4 is designed for compatibility with standard telecom fuse blocks and sealed enclosures thanks to its miniature, non-indicating form. Ensure proper fitment within a compatible holder and verify clearances around the fuse area to prevent heat buildup. Use standard packaging to simplify stocking and procurement, reducing field installation time and errors.
TPM-4 is rated for 4 A current with an 80 Vdc voltage rating and a 20 kAIC interrupt capacity. It is ideal for protecting telecom power rails in data centers, line cards, and network equipment where space is limited and fast fault interruption is critical to minimize damage and downtime.
Yes. Its miniature, standard-packaged form factor supports high-density installations, while the 20 kAIC interrupt capability delivers reliable fault protection in compact rack-mount and cabinet environments. This combination helps maximize rack space without compromising safety or performance.
The TPM-4 carries CE Marked compliance, signaling conformity with European safety and performance standards. This certification facilitates regulatory acceptance, simplifies supplier qualification, and supports compliance in multinational telecom and data-center deployments where European markets are involved.
The TPM-4’s fast current-limiting action minimizes fault energy and protects critical equipment, reducing repair costs and downtime. Its non-indicating design lowers routine inspections in sealed enclosures, while standard packaging streamlines procurement and inventory. Together, these factors yield improved uptime, lower maintenance labor, and a faster payback in telecom protection applications.
