Feature: Amperage Rating and Interrupt Capability. The 1 A rating combined with a 1 kAIC interrupt rating at 300 Vdc ensures fast clearing of faults in telecom circuits while avoiding unnecessary outages. Business impact: tighter protection reduces equipment wear, minimizes arc-on-fault duration, and lowers maintenance costs. Application: telecom line cards, network interfaces, and data-communication modules in small to medium enclosures. Feature: Electrical Ratings and Versatility. With voltage ratings of 125 Vac and 300 Vdc, this fuse supports mixed-supply installations and simplifies stocking in multi- voltage telecom racks. Business impact: simplifies procurement and asset management while maintaining compliance. Application: mixed-voltage telecom cabinets, data centers, and edge devices. Feature: Ferrule End Terminations. Ferrule end x ferrule end connections deliver secure, vibration-resistant terminations suitable for tight panel layouts. Business impact: reduces risk of loose terminations, improves reliability, and speeds swap-outs during maintenance windows. Application: backplanes, patch panels, and equipment racks in industrial environments. Feature: Visual Identification and Form Factor. Color code pink enables rapid identification in crowded panels, decreasing mis-selection risk. Business impact: lowers installation errors and accelerates spare-part picking. Application: high-density telecom enclosures, systems with multiple fuse types. Feature: Compliance and Compatibility. CE marking ensures European safety compliance; part of the Bussmann 70 Series, spacing and footprint align with standard holders. Business impact: simplifies integration with existing protection schemes and reduces design validation time. Application: telecom equipment and data-communication devices using Bussmann 70 Series holders. Feature: Physical Specifications and Handling. With dimensions 1.63 in length, 2.5 in height, and 0.42 in width, plus 0.5 lb weight, it is compact for dense panels. Business impact: supports high-density layouts and easy logistics. Application: panel-based telecom protection in compact enclosures.

FAQs
The 70I-1A uses ferrule-end terminations designed to drop into standard Bussmann 70 Series holders and compatible panel layouts. This ensures secure, vibration-resistant connections and straightforward cross-reference in BOMs. For replacement, stock alignment with other 70 Series fuses minimizes variance and reduces procurement complexity.
Key specs are 1 A amperage, 125 Vac and 300 Vdc voltage ratings, and a 1 kAIC interrupt rating at 300 Vdc. This combination protects telecom circuitry from overcurrent events while allowing operation across dual-supply environments. Consider using this fuse in circuits that require precise, fast-acting protection.
Yes. Its compact form factor (1.63 in L, 2.5 in H, 0.42 in W) and pink visual coding support quick identification in crowded panels. Ferrule terminations enable secure, rapid swaps, aiding maintenance in dense telecom enclosures, patch panels, and data-center edge devices.
The fuse is CE Marked, indicating conformity with European safety standards for telecom protection. The data does not list SIL or IP certifications. For project compliance, reference CE marking and Bussmann 70 Series compatibility, and verify site-specific regulatory requirements before deployment.
The 70I-1A offers reliable protection with predictable blow characteristics, reducing unexpected outages. Easy field replacement and a standardized form factor lower maintenance time and spare-part handling costs. Quick pink-coding and secure ferrule terminations translate to faster diagnostics and improved uptime in telecom racks and data-center gear.
