70C-3A

Quick Summary

The Eaton 70C-3A telecommunication fuse provides reliable overcurrent protection for telecom circuits in data centers and field installations. Engineers often struggle with selecting fuses that prevent nuisance trips while safeguarding sensitive equipment during voltage transients. This device carries CE Marking, ensuring compliance with European safety standards, and supports 125 Vac and 300 Vdc systems with a robust 1 kAIC interrupt rating. By using a standard ferrule-end, non-indicating fuse from the Bussmann 70 Series, technicians streamline maintenance and improve uptime across network equipment, racks, and remote sites. The combination of precise ratings, clear color coding, and proven Bussmann design translates to measurable efficiency gains and safer, compliant protection in critical electrical protection & circuit control applications.

Special features
Color code blue
Feature → Business Impact → Application: 125 Vac / 300 Vdc rating aligns with mixed telecom power rails, reducing risk of under or over protection and enabling consistent protection across devices. This translates to lower failure rates and improved equipment lifespan in data centers and field installations. Feature → 3 A amperage rating provides targeted protection for small- to mid-size telecom circuits, minimizing downtime and protecting sensitive electronics in UPS-fed telecom cabinets and network gear. Feature → 1 kAIC interrupt rating at 300 Vdc enables rapid fault interruption in high-energy telecom nodes, decreasing potential arc damage and service interruptions in centralized and distributed network environments. Feature → Ferrule end x ferrule end connection supports quick, secure installation with standard ferrule terminals, reducing assembly time and field errors during panel wiring and rack deployment. Feature → Non-indicating fuse with color code blue simplifies identification in crowded electrical panels, enabling faster troubleshooting and inventory management while maintaining a clean maintenance workflow. Feature → 70 Series compatibility ensures availability of datasheets, catalogs, and service bulletins, helping procurement teams consolidate parts across telecom protection schemes and standardize spares across sites. Feature → CE Marked compliance provides regulatory assurance for European installations, supporting shop-floor and site audits, while the blue color and standard packaging improve stock control and onboarding for new technicians.

FAQs

The 70C-3A uses ferrule-end x ferrule-end connections designed for standard ferrule terminals. Ensure the mounting panel accepts the 0.42 in width and fits within the 1.63 in depth and 2.5 in height. Verify voltage and current ratings (125 Vac / 300 Vdc, 3 A) match the protected circuit and use only non-indicating Bussmann 70 Series devices to maintain consistent maintenance procedures.
The fuse is rated 3 A with an interrupt rating of 1 kA at 300 Vdc and supports 125 Vac operation and 300 Vdc, enabling fast fault clearance while protecting telecom loads. These specs translate to reliable protection for small power rails in telecom racks, network switches, and line cards, reducing the risk of collateral damage from short circuits.
The 70C-3A is part of the Bussmann 70 Series and datasheets reference AT&T Columbus fuse contexts, indicating design compatibility with legacy telecom protection schemes. Always confirm connector type, voltage rails, and interrupt requirements for your specific network equipment, and consult the Eaton datasheet for exact compatibility notes.
The device carries CE Marking, indicating compliance with European safety standards for electrical protection components. This certification supports regulatory alignment in European deployments and simplifies audit trails for telecom protection installations across data centers and field sites.
By preventing nuisance trips on transient events while delivering fast fault interruption (1 kAIC at 300 Vdc), the 70C-3A helps maintain uptime for critical networks, reduces unplanned maintenance, and lowers asset damage costs. Its standardized ferrule-end design also reduces installation time and inventory complexity for spare parts.
