Eaton TPN-10 Telecommunication Fuse - 100 kAIC
Part Number: TPN-10
Quick Summary
TPN-10 telecommunication fuse protects sensitive telecom power circuits by interrupting faults quickly. This addresses common downtime and nuisance trips caused by mismatched protection devices in data centers and network racks. While the data sheet notes Not Applicable for Warranty and Compliances, the model delivers a robust 170 Vdc rating with 10 A capacity and a high 100 kAIC interrupt rating, reinforcing reliability in demanding environments. The non-indicating design minimizes panel clutter, and silver-plated terminals ensure durable, low-resistance connections. As you scale protection across mid-range telecom budgets, this fuse aligns with Eaton Bussmann series standards, simplifying procurement and field replacements while reducing total cost of ownership.

FAQs
To install the TPN-10, locate a suitable fuse holder designed for Bussmann series devices, align the fuse with the bus contacts, and secure the silver-plated terminals to the termination points. The non-indicating design simplifies panel layout, while the 170 Vdc rating and 10 A current rating ensure compatibility with standard telecom DC power rails. Verify enclosure clearance and follow site wiring practices for DC circuits.
The TPN-10 is specified as current-limiting, which means it quickly reduces let-through current when a fault occurs. This minimizes fault energy, reduces overheating risk for downstream conductors, and helps protect power supplies and wiring in telecom DC paths. This characteristic is especially valuable in data centers and network cabinets where rapid fault clearance preserves uptime and equipment life.
Yes. The TPN-10 is designed for telecom power circuits common in data centers, offering a 170 Vdc rating, 10 A capacity, and a 100 kAIC interrupt rating. Its current-limiting action and robust terminals support reliable protection of DC power distribution units, racks, and other critical infra, while its compact form simplifies integration in dense cabinets.
The provided data marks warranty and compliance fields as Not Applicable for this model. For region-specific certifications such as CE, IP, or SIL, consult Eaton’s official datasheets or contact the manufacturer to confirm current approvals for your installation and jurisdiction.
Expect reduced downtime due to rapid fault clearing and lower maintenance overhead thanks to the non-indicating design which minimizes on-panel signaling. The high interrupt rating (100 kAIC) and durable silver-plated terminals contribute to longer service life and lower replacement costs in telecom and data-center environments, delivering a favorable total cost of ownership over the protection circuit’s lifetime.
