Eaton TPW-200 Telecommunication Fuse - 100 kAIC
Part Number: TPW-200
Quick Summary
The Eaton TPW-200 telecommunication fuse provides fast-acting overcurrent protection for DC telecom power and data networks. Engineers contend with nuisance trips and selecting protection that does not compromise uptime in harsh telecom environments. The data lists 80 Vdc, 200 A and 100 kAIC as the key electrical ratings; while explicit certifications aren’t shown, verify CE and UL (or your local approvals) with Eaton for regional compliance. Using this non-indicating fuse in DC distribution panels supports high reliability, reduced maintenance, and easier asset management in telecom and data-center environments. This aligns with aggressive uptime targets and helps procurement simplify categorization of DC protection components.

Feature: DC protection performance. The TPW-200 is rated for 200 A continuous, 80 Vdc maximum, with a 100 kAIC interrupt rating, delivering reliable fault clearance for telecom DC buses. This high interrupt capability reduces the chance of auxiliary equipment damage during a short circuit and minimizes hot spots in power circuits. Business impact: greater system resilience translates to lower MTTR and longer asset life in critical telecom and data-center applications. Application context: suited for DC distribution panels, telecom racks, and remote switching environments where fast, decisive protection is essential. Feature: Non-indicating design with practical benefits. The fuse does not include a visual status indicator, which keeps enclosures compact and reduces wiring complexity. This simplifies retrofits and field upgrades where space is at a premium. Business impact: reduced hardware costs and simpler stocking of spare fuses; application: retrofit projects in dense telecom cabinets and edge computing nodes. It also pairs well with remote monitoring schemes where status is inferred from upstream monitoring. Feature: Ecosystem compatibility. TPW-200 is designed to integrate with Eaton's Telpower double-wide fused disconnect switches, supported by datasheets such as TPW DS 5028. This alignment ensures predictable panel layouts, harmonized future upgrades, and easy spare-part provisioning. Business impact: faster installation, reduced commissioning risk, and scalable protection across multi-rack deployments; application: telecom central offices, data-center distribution rooms, and field-deployed power cabinets. Feature: procurement and identification. Catalog Number TPW-200 and UPC 051712500906 enable clean BOMs, accurate job costing, and streamlined procurement workflows. Business impact: lower order errors, improved inventory control, and faster job completion in network rollouts; application: system integrators and OEMs specifying DC protection for telecom builds. Installation considerations and practical guidance. While the data notes Not Applicable for warranty and compliances, practitioners should validate regional approvals and rely on Eaton datasheets for installation instructions and safety practices. Real-world experience shows that pairing the TPW-200 with compatible disconnect switches and correct fault-current settings yields reliable DC protection with minimal total cost of ownership.

FAQs
The TPW-200 is designed for high-current DC protection in telecom power systems. It provides a 200 A rating with an 80 Vdc limit and a 100 kAIC interrupt capability, making it ideal for DC distribution panels, telecom racks, and remote site equipment where fast fault clearance helps prevent equipment damage and downtime.
Install the TPW-200 as part of the Telpower double-wide fuse ecosystem, ensuring proper coordination with compatible disconnect switches and the enclosure’s rated fault current. Refer to the TPW datasheets for recommended mounting, clearance, and wiring practices to ensure reliable protection and easy field servicing.
No. The TPW-200 is a non-indicating fuse, which keeps panel layouts compact and reduces wiring complexity. If status visibility is required, plan for upstream monitoring or downstream indicators in the protection scheme while maintaining the same protection performance.
The product data lists Not Applicable for compliances. For regional regulatory compliance, verify with Eaton whether CE, UL, or other applicable certifications are current for your installation site and panel configuration before deployment.
The 100 kAIC interrupt rating provides robust fault-current clearance, protecting power rails and connected equipment from severe short-circuit conditions. This improves system uptime, reduces risk of collateral damage in DC feeders, and supports reliable operation in dense telecom and data-center power architectures.
