Eaton TPN-110 Telecommunication Fuse - 100 kAIC
Part Number: TPN-110
Quick Summary
The Eaton TPN-110 Telecommunication fuse provides reliable, current-limiting protection for telecom power interfaces. In dense network racks, nuisance outages and slow fault isolation hinder uptime and drive maintenance costs. For safety-critical deployments, high interrupt ratings and conformity to safety standards matter; telecom protection devices are typically designed to align with CE safety requirements and UL/IEC guidelines. With a compact 1.5 in by 7 in footprint and silver-plated terminals, the TPN-110 integrates smoothly into standard fuse blocks and rugged enclosures. This combination helps safeguard critical network hardware, reduces downtime, and lowers lifecycle costs by minimizing replacement needs and service interrupts.

Eaton Specification Sheet - TPN-110
The TPN-110 delivers a high-interrupt, current-limiting protection profile that minimizes damage to downstream telecom equipment during a fault. This translates to shorter downtime and lower repair costs in data centers, carrier hotels, and remote network sites. Its 170 Vdc rating supports DC power architectures common in telecom infrastructure, enabling safer operation of DC distribution and battery-backed lines. The non-indicating design reduces maintenance complexity in large racking where status indicators may be hard to read, while still providing rapid, reliable protection when a fault occurs. Silver-plated terminals resist corrosion in varying environmental conditions, extending service life in outdoor cabinets or damp telecom rooms. The fuse’s compact footprint and standard Bussmann-series compatibility simplify installation in existing fuse blocks and power distribution assemblies, saving time during upgrades or replacements. Overall, the TPN-110 helps engineers meet reliability targets while controlling maintenance costs in mission-critical networks.

FAQs
The TPN-110 fits standard Bussmann-series holders and fuse blocks thanks to its compact 1.5 in by 1.5 in footprint and 7 in height. Use with compatible DC power distribution units in telecom cabinets or data-center riser rooms. Ensure proper clearance for heat dissipation and verify wiring to the 170 Vdc system with silver-plated terminals to resist corrosion over time.
With a 110 A rating and a 100 kAIC interrupt capacity, the TPN-110 delivers rapid fault interruption, protecting sensitive telecom equipment from short-circuit or overload events. Its current-limiting action minimizes fault energy transfer, reducing arcing and collateral damage in data centers and network devices.
The product data provided lists Compliances as Not Applicable, so confirm specifics with Eaton’s datasheets for regional certifications. In practice, telecom fuses of this type are designed to align with common safety frameworks such as CE and UL/IEC guidance for electrical protection devices; always verify in the Eaton specification sheet before procurement for your market.
Key specs are 170 Vdc voltage rating, 110 A amperage rating, and 100 kAIC interrupt rating. The fuse is current-limiting and non-indicating, with silver-plated terminals to improve durability in varied environments. These characteristics support DC power protection in telecom networks and data centers.
A non-indicating fuse reduces panel clutter and simplifies replacement planning in large installations. The high interrupt rating and silver-plated terminals extend service life in harsh environments, lowering replacement frequency. Compact form factor reduces cabinet space requirements, enabling scalable deployments and lower total cost of ownership over the system’s lifetime.
