Eaton 70N-10A Telecommunication Fuse - 1 kAIC at 300 Vdc
Part Number: 70N-10A
Quick Summary
Telecommunication fuse by Eaton protects telecom circuits with reliable overcurrent protection. This device is designed for dependable protection in telecom racks, data centers, and field installations where uptime is critical. CE marking paired with an 125 Vac / 300 Vdc voltage rating and a 1 kAIC interrupt capability provides robust safety margins for sensitive communication equipment. In dense panel environments, nuisance trips and mis-sized protection can derail service availability; the 70N-10A helps mitigate that risk by matching circuit requirements to actual fault currents. Its ferrule-end construction, color-code violet/yellow, and compact form factor simplify installation, inventory control, and preventative maintenance across modern telecom infrastructure.

Feature to benefit mapping drives real business value. The 70N-10A offers a 10 A amperage rating with a 125 Vac and 300 Vdc voltage rating, delivering precise overcurrent protection for telecom power rails while reducing the likelihood of nuisance trips in normal operation. This translates to lower mean time to repair (MTTR) and improved equipment availability in switchgear, network cabinets, and telecom server rooms. The 1 kAIC interrupt rating at 300 Vdc ensures reliable fault interruption for high-energy transients common in data centers and field installations, supporting safety compliance and asset protection. Ferrule end x ferrule end connections enable fast, repeatable installation with common terminal blocks, minimizing assembly time and installer error. The color code violet/yellow provides quick visual verification during maintenance cycles and stock management. Non-indicating fuse design reduces false indicators in crowded panels, improving diagnostic efficiency. The standard packaging type aligns with existing supply chains, ensuring consistent sourcing and easy replacement planning.

FAQs
Install the 70N-10A using ferrule-terminals compatible with standard fuse holders. Ensure power is disconnected before replacement, align the ferrule ends with the terminal block, and press firmly to seat. Verify the color code violet/yellow for quick visual confirmation during routine maintenance. The non-indicating design reduces false diagnostics in crowded panels.
The 70N-10A carries a 10 A amperage rating, 125 Vac and 300 Vdc voltage ratings, and a 1 kAIC interrupt rating at 300 Vdc. These specs suit telecom line cards, network power rails, and telecom equipment operating within those voltage ranges, providing reliable overcurrent protection while minimizing disruption from transient faults.
The product documentation specifies CE marking and electrical ratings but does not specify an IP rating or outdoor suitability. For outdoor deployments, use in a protective enclosure or cabinet with an appropriate ingress protection rating to safeguard against moisture, dust, and environmental variables while maintaining the fuse’s electrical performance.
The fuse uses ferrule ends (ferrule end x ferrule end) and ships in standard packaging, designed for quick stocking and replacement. Its compact dimensions—1.63 in length, 2.5 in height, and 0.42 in width—support dense panel layouts. The violet/yellow color code aids in rapid identification during commissioning and maintenance.
The data indicates the warranty is Not Applicable for this specific fuse. Despite that, the 70N-10A is engineered for high reliability with a 1 kAIC interrupt rating and CE Marked compliance, which supports predictable protection and can contribute to reduced downtime and maintenance costs over its service life when properly installed.
