Eaton TPM-25 Telecommunication Fuse - CE Marked, 80 Vdc
Part Number: TPM-25
Quick Summary
The Eaton TPM-25 telecommunication fuse provides fast, current-limiting protection for telecom and data circuits. This helps prevent outages and equipment damage caused by overcurrents during fault events or surges. It carries CE Marked compliance and is designed for 80 Vdc operation with a 25 A rating and 20 kAIC interrupt capacity. Using this miniature, non-indicating fuse helps simplify panel layouts while delivering reliable protection, reducing downtime and maintenance costs. For procurement and installation, engineers gain predictable performance, easy sourcing from the Bussmann TPM line, and compatibility with standard fuse holders.

With a 25 A, 80 Vdc rating and 20 kAIC interrupt capacity, TPM-25 delivers robust overcurrent protection. This translates to reduced fault energy and minimized risk of cascade failures, protecting downstream electronics and extending equipment life. It is well suited for telecom racks, data equipment, and network infrastructure where fast isolation is critical. Current-limiting action reduces fault energy and shields sensitive circuitry; this translates into cooler operation and longer service intervals for telecom power supplies. The non-indicating profile simplifies installation in crowded panels and cable routes, while external indicators can be added if status monitoring is required. Compact, miniature form factor and standard packaging streamline installation in compact telecom enclosures; this saves panel space and simplifies retrofit or expansion projects. CE Marked compliance ensures alignment with EU safety requirements, making procurement straightforward across international sites. It supports reliable protection with minimal panel impact, enabling faster deployments in network infrastructure projects.
