Eaton Specification Sheet - 70M-8A
Feature → Business Impact → Application: 0.25 A rating with 125 Vac / 300 Vdc and 1 kAIC interrupt rating ensures selective protection for telecom circuits, reducing the risk of nuisance trips and costly downtime in control panels. This precise rating translates to improved equipment uptime and fewer false positives during peak loads in data-center and network equipment. Application: ideal for control cabinets, telecom racks, and distributed I/O in industrial environments where reliability and rapid serviceability matter. Feature → Business Impact → Application: Ferrule-end x ferrule-end connections and color code violet/white support quick eye‑checks and fast field installations. Application: simplifies replacement in service windows and minimizes mis-wiring in high-density panels. Feature → Business Impact → Application: CE Marked compliance provides regulatory confidence for European deployments, improving supplier qualification and downstream procurement. Application: helps OEMs meet safety standards while maintaining lean inventories. Feature → Business Impact → Application: Non-indicating fuse design reduces visual clutter in crowded enclosures, cutting maintenance time and training requirements. Application: supports technicians in high-traffic environments for faster fault isolation.

FAQs
Install the 70K-1/4A using ferrule-end terminations into a compatible Bussmann 70 series holder. Ensure the circuit is de-energized, verify the 0.25 A rating matches the protection requirement, and insert the fuse so the color code is visible for quick identification. Confirm the holder supports non-indicating fuses and that the assembly is properly seated to avoid arcing or loose connections. After installation, perform a functional test to confirm protection is active and that no nuisance trips occur under normal operating loads.
Key performance specs include a 0.25 A amperage rating, 125 Vac / 300 Vdc voltage rating, and a 1 kAIC interrupt rating at 300 Vdc. This combination provides selective protection for low‑current telecom circuits, allowing fast interruption during faults while minimizing nuisance trips. The non-indicating design simplifies replacement, and the ferrule-end termination ensures robust, low-resistance connections in control panels and telecom enclosures.
Yes. The 70K-1/4A uses ferrule-end terminations designed for compatibility with standard Bussmann 70 series holders and similar clips in telecom and control panel assemblies. The ferrule-end x ferrule-end configuration supports secure, repeatable connections, enabling straightforward field servicing and minimizing the risk of loose contacts that can trigger false trips or thermal damage during fault events.
The 70K-1/4A is CE marked, signaling compliance with European safety directives for electrical components. This certification supports regulatory acceptance in many markets and aligns with industry expectations for telecom protection devices. While additional regional requirements may apply, CE marking provides a clear baseline for safe and compliant operation in European installations.
The 70K-1/4A can reduce total cost of ownership by lowering downtime due to nuisance trips, thanks to its precise 0.25 A rating and reliable 1 kAIC fault interruption. Its ferrule-end design lowers installation time and field rework, while the color-coded violet/white helps technicians quickly identify the correct fuse during maintenance. These factors translate to faster service, fewer spare part mismatches, and improved asset uptime.
