Eaton TPM-8 Telecom Fuse - 80 Vdc, 20 kAIC, CE Marked
Part Number: TPM-8
Quick Summary
The Eaton TPM-8 telecommunication fuse provides fast, current-limiting protection for telecom power rails and networks. In crowded panels, small size and non-indicating operation can complicate reliability and fault diagnosis. CE Marked compliance and durable thermo-plastic housing support safe, compliant deployments in telecom equipment. By combining robust current-limiting performance with a compact form, it enables cost-efficient procurement and faster installation. Its 20 kAIC interrupt rating ensures quick fault isolation, reducing arc energy and protecting power supplies during short circuits. Being part of the Eaton Bussmann family, TPM-8 is readily stocked and compatible with existing Bussmann-series carriers, simplifying procurement for maintenance teams. This translates to lower maintenance costs, shorter downtime, and more reliable telecom network operation.

FAQs
Yes. TPM-8 is designed as a miniature, current-limiting telecom fuse compatible with standard Bussmann-series fuse holders and clips. It supports easy integration in compact telecom panels and DIN-rail environments. When installing, ensure correct orientation, secure clipping, and proper clearance around the fuse body to maintain thermal performance and fault visibility within the enclosure.
TPM-8 is rated at 8 A with an 80 Vdc voltage rating and delivers a 20 kAIC interrupt rating. It is a non-indicating, current-limiting fuse in a miniature package with a CE Marked compliance. These ratings enable fast fault clearing in DC telecom circuits while protecting downstream equipment from overcurrent conditions.
TPM-8 is well suited for telecom power rails, network backplanes, data-center interconnects, and telecom switches where compact protection is needed without indicators that could complicate panel diagnostics. Its small form factor and high interrupt rating support high-density racks, remote sites, and crowded cabinet configurations while maintaining reliable fault isolation.
TPM-8 carries CE Marked compliance, indicating conformity with European safety directives. While the data set emphasizes CE compliance, users should verify any additional regional requirements (such as RoHS or local safety standards) in their specific deployments. The device is designed to meet typical electrical protection standards expected in European telecom installations.
TPM-8 helps reduce maintenance disruption by delivering reliable, fast fault isolation with a compact footprint, enabling higher-density installations. Its compatibility with the Eaton Bussmann family simplifies spare parts management, lowers stocking complexity, and contributes to shorter downtime during fault events, translating to lower maintenance costs and improved network uptime.
