Eaton TPW-150 Telecommunication Fuse - 100 kAIC
Part Number: TPW-150
Quick Summary
The Eaton TPW-150 telecommunication fuse protects critical telecom circuits in racks and cabinets. Unplanned overcurrent events can stall service, delay deployments, and drive expensive field replacements. In practice, the TPW-150 delivers 80 Vdc, 150 A and 100 kAIC interrupt performance for robust network protection. While this data sheet notes non-indicating status and standard packaging, it supports streamlined installation and predictable maintenance cycles. For your purchase decisions, consider compatibility with Telpower equipment and your regional compliance requirements. This combination of ratings and a compact form factor helps reduce spare-part inventories while preserving uptime for telecom infrastructure. Engineers will appreciate the data-sheet cross-references and the option to consult Eaton for application-specific guidance.

FAQs
TPW-150 is designed for drop-in compatibility with Telpower double-wide fused disconnect switches, aligning with Bussmann series data sheet no. 5028. This enables quick retrofits and standardized spares across telecom cabinets. Ensure matching catalog numbers during procurement and verify that your enclosure design accommodates the non-indicating TPW style while maintaining safe clearances.
TPW-150 offers an 80 Vdc voltage rating, 150 A current rating, and a 100 kAIC interrupt rating. These specs mean it can safely interrupt large fault currents on DC telecom power rails, minimizing damage to power supplies and connected equipment while preserving service continuity in data centers and telecom racks.
Yes, TPW-150 is purpose-built for 80 Vdc telecom networks. It is well-suited for telecom racks, switchgear, and data-center distribution frames where dependable overcurrent protection is essential to prevent costly outages and extend equipment life in high-density deployments.
The data provided does not list specific certifications. Before deployment, verify with Eaton for regional certifications (such as CE, UL, IEC) applicable to your market. Confirm that the TPW-150 meets your facility’s safety and regulatory requirements and that any external fault-indication methods align with your maintenance practices.
Using TPW-150 can lower downtime and repair costs by delivering high interrupt capability, protecting power rails from faults. The non-indicating design reduces panel clutter and spare-parts complexity, though you should implement external monitoring for fuse status. Overall, the solution supports fewer outages, faster replacements, and more predictable lifecycle planning for telecom networks.
