Eaton TPN-200 Telecommunication Fuse - 170 Vdc 200 A 100 kAIC
Part Number: TPN-200
Quick Summary
TPN-200 telecommunication fuse protects critical electrical systems in telecom and data-center networks. Engineers often contend with outages caused by unprotected DC rails, where nuisance trips erode uptime and increase maintenance. This model delivers 170 Vdc, 200 A, and 100 kAIC interrupt performance, with a non-indicating design that keeps control panels clean. Note: The data sheet does not list CE, SIL, or IP certifications; verify with Eaton's specification sheet to meet your regulatory requirements. By pairing this fuse with a Bussmann series protection strategy, facilities gain predictable protection, simplified procurement, and better overall reliability.

Eaton Specification Sheet - TPN-200
DC rating and high interrupt capability: The TPN-200 is rated for 170 Vdc, 200 A with a 100 kAIC interrupt rating. The result is fast, current-limiting protection that reduces let-through energy during faults, helping to prevent damage to power supplies and downstream electronics. Application: telecom power distribution, data-center equipment power rails, and network chassis. Current-limiting and non-indicating design: It limits fault currents and reduces arc energy, while non-indicating construction keeps panel status clean, minimizing wiring complexity. Application: panel boards and in-rack protection where external indicators are available. Silver-plated terminals: Enhanced conductivity and corrosion resistance improve reliability in harsh telecom environments, reducing contact resistance over time. Application: rugged installations in racks and cabinets. Compact form factor and standard packaging: 1.5 in length, 1.5 in width, and 7 in height with a 0.94 lb weight allow easy drop-in replacement and retrofits in existing enclosures. Application: retrofit into mainstream Bussmann series protection schemes and industry-standard telecom enclosures. Compatibility and supplier support: Part of the Eaton Bussmann series, enabling consistent procurement, dependable supply, and aligned service from a single vendor, reducing maintenance planning time. Addressing common objections: If you require built-in sensing, plan for external indicators; if regulatory specifics are essential, verify the exact CE or IP scope via the Eaton datasheet. This approach yields measurable results in uptime, maintenance cost reduction, and streamlined panel design overall.
