Eaton TPS-25V Telecommunication Fuse - CE Marked
Part Number: TPS-25V
Quick Summary
TPS-25V Telecommunication fuse from Eaton protects telecom enclosures and network equipment by interrupting fault currents. In field deployments, nuisance outages and unexpected downtime challenge uptime and maintenance budgets. CE Marked ensures European compliance, and the device delivers 25 A at 170 Vdc with a 100 kAIC interrupt rating in a non-indicating, current-limiting design. Its vertical PCB tab simplifies mounting in compact panels, while glass-melamine construction and silver-plated ferrules boost reliability. This combination delivers faster protection, easier procurement, and lower total cost of ownership for telecom protection architectures.

Eaton Specification Sheet - TPS-25V
Vertical PCB tab design enables direct PCB mounting, simplifying installation and reducing PCB footprint in dense telecom enclosures. This reduces assembly time and potential wiring errors, delivering faster deployment for network equipment and fiber termination panels. The current-limiting, non-indicating fuse provides robust fault protection without visible indicators that can complicate signaling in crowded racks, improving maintenance predictability and reducing nuisance alarms. With a 25 A rating, 170 Vdc capability, and 100 kAIC interrupt strength, TPS-25V protects DC telecom rails from transient faults while maintaining fast clearance, helping equipment stay in specification under fault conditions. The glass melamine tube construction with silver-plated brass ferrules enhances mechanical durability and contact reliability in rugged telecom environments, supporting longer service intervals and lower replacement costs. CE Marked compliance and standard packaging streamline procurement and integration into existing protection schemes, enabling consistent performance across European and global deployments. The compact dimensions (0.56 in W x 0.56 in D x 0.88 in H) and lightweight form factor enable easy stocking and rapid swapouts in field service and rack-mounted installations. These features translate to lower lifecycle costs and improved uptime for critical telecom assets.
