Eaton Specification Sheet - TPM-7
Current-limiting design with a 20 kAIC interrupt rating provides rapid fault energy cutoff, protecting downstream electronics and reducing collateral damage across DC rails in telecom gear. This capability minimizes damage to power supplies and line cards during short circuits, helping to shorten outage durations and simplify fault diagnosis. In practice, field technicians appreciate the predictable behavior, which supports quicker restores and safer maintenance. For distributed telecom architectures, the TPM-7 delivers robust protection without compromising overall system availability. 80 Vdc voltage rating makes the TPM-7 suitable for common telecom DC rails and battery-backed back-ups, reducing arcing risk and enabling straightforward integration with standard power supplies. The miniature, rugged package fits tight enclosures and vertical mounting, while standard packaging simplifies stocking and replacement in service centers. The fuse’s non-indicating design keeps panels uncluttered, reducing wiring complexity during installation and modernization projects. With a 7 A amperage rating, the TPM-7 provides selective protection for typical branch circuits feeding network equipment, balancing reliable protection with high availability. This rating aligns with common DC distribution schemes in data centers and central offices, minimizing nuisance trips while preserving critical uptime. Its catalog-number clarity and compact form accelerate procurement, testing, and rollout across fleets. Non-indicating construction and compact dimensions make the TPM-7 ideal for dense telecom cabinets where space is at a premium. The lack of visual indicators reduces potential points of failure in indicator circuits and simplifies field replacements. Engineers can deploy the TPM-7 across multiple platforms with confidence, knowing replacement parts are readily available through Eaton's standard channels. CE Marked compliance signals adherence to European safety standards, supporting regulatory approvals and cross-border deployments. Standardization of the TPM-7 across fleets helps procurement teams reduce part variety and simplify maintenance, yielding lower total cost of ownership. In short, this fuse combines protection strength with supply-chain efficiency for mission-critical telecom networks.

FAQs
To install TPM-7, select an appropriate fuse holder compatible with 80 Vdc DC rails and the TPM-7 catalog number. Ensure the holder is rated for 7 A and 20 kAIC interrupt rating and mount in a clean, ventilated enclosure to prevent overheating. Verify electrical connections follow the equipment’s wiring schema, and place the fuse in the positive supply leg to ensure proper protection and easy fault isolation.
TPM-7 combines an 80 Vdc rating with a 7 A current rating and a 20 kAIC interrupt level, delivering fast protection for DC telecom rails while minimizing downstream damage. Its compact size and CE marking support European deployments, while the non-indicating design simplifies integration in space-constrained equipment such as line cards and DC power supplies.
Yes. TPM-7 uses standard Bussmann series cataloging and standard packaging, allowing straightforward substitution in existing holders and panel layouts. Its 7 A, 80 Vdc ratings match common telecom protection schemes, reducing the need for adapter kits. Always verify holder compatibility with the manufacturer’s installation guidelines and ensure proper torque on terminals.
TPM-7 is CE Marked, indicating compliance with European health, safety, and environmental requirements. This certification supports regulatory clearance for European deployments and helps meet internal compliance standards for telecom equipment. If you require additional certifications such as UL or IP ratings, verify the specific order or contact Eaton for documentation tied to your lot.
Using TPM-7 can lower maintenance costs by reducing downstream damage during faults and shortening service interruptions. Its quick fault energy control minimizes cascading failures on DC telecom rails, while its compact footprint and standardized catalog number streamline stocking and deployment across fleets. Operators typically experience improved uptime and more predictable maintenance schedules.
