FAQs
The TPN-20 is designed for standard telecom fuse bases used with Eaton Bussmann series. Verify the base footprint (compact 0.56 in width, 2 in height) and wire the 170 Vdc rail with appropriately rated conductors. Ensure proper isolation of DC rails during servicing and use external status indicators if monitoring is required since the fuse is non-indicating.
TPN-20 provides 170 Vdc voltage rating, 20 A amperage, and a 100 kAIC interrupt rating. The 100 kAIC rating means it can interrupt a fault current up to 100 kiloamps at its rated voltage, offering robust protection for high-energy telecom DC networks and reducing the risk of cascading failures.
Yes. Its 170 Vdc rating and 20 A capacity suit telecom DC rails in data centers, network equipment cabinets, and outdoor telecom enclosures. The current-limiting design minimizes fault energy, while the compact form factor supports dense panel layouts common in modern data-center and field deployments.
The provided data for this entry lists warranty and compliance as Not Applicable, and no certifications are specified here. For definitive CE/UL or IEC certifications, consult the official Eaton Bussmann datasheet or contact Eaton technical support to confirm current certification status for your region and application.
The TPN-20 offers robust protection with a high interrupt rating and current-limiting behavior, reducing fault energy and downtime. Silver-plated terminals improve long-term reliability in challenging environments, lowering maintenance costs and extending component life in telecom DC rails, which translates to a lower total cost of ownership across multi-site deployments.
