Feature → Business Impact → Application: 80 A amperage rating provides strong protection against overcurrent events in standard control circuits, reducing the risk of equipment damage and unplanned downtime in industrial panels. This enables faster start-ups and lower maintenance costs when used in motor control and general protection duties within sensitive machinery. Application: suitable for industrial control panels and automation cabinets requiring reliable, non-current-limiting protection without frequent nuisance trips.Feature → Business Impact → Application: 10 kAIC interrupt rating at 600 Vac delivers a high fault-clearing capability, improving safety margins during short circuits and facilitating compliant equipment protection in high-energy applications. Application: ideal for machine disconnects and power distribution within manufacturing lines where robust fault protection is essential.Feature → Business Impact → Application: Non-current-limiting design reduces nuisance tripping in normal operation, while ensuring clear isolation during faults. This supports smoother startup sequences and reduces unnecessary maintenance interventions. Application: general-purpose protection in control circuits where precise coordination with upstream protection is required.Feature → Business Impact → Application: Blade end x blade end connections and standard packaging simplify retrofits and panel mounting, cutting installation time and minimizing wiring errors. Application: easy integration into existing Bussmann series holders and control panels, accelerating deployment in new builds or upgrades.Feature → Business Impact → Application: Compact dimensions and standard packaging (7.9 in L, 1.34 in W/H) enable efficient enclosure layout and stocking. Application: fits in compact electrical cabinets and simplifies inventory management for distributors and OEMs.Feature → Business Impact → Application: Certifications and class designation (CE Marked, Class H / K5) support regulatory compliance and design standard alignment, reducing qualification effort for end users. Application: suitable for regulated industrial environments needing traceable and auditable protection components.

FAQs
NOS-80 uses blade-end x blade-end connections designed for standard Bussmann series holders. It measures 7.9 in long with 1.34 in width and height, packaging is Standard, and the unit ships in quantities of five, facilitating straightforward retrofits and stocking in typical industrial control panels.
NOS-80 is rated for 80 A with an interrupt rating of 10 kAIC at 600 Vac, and a voltage rating of 600 V. It is a non-current-limiting fuse (Class H / K5) intended for general protection in control circuits and panel applications.
NOS-80 provides general-purpose, non-current-limiting protection suitable for many panel applications. For motors with significant inrush, assess coordination with upstream protection and consider current-limiting alternatives if nuisance trips or startup surge protection are critical design constraints.
The NOS-80 is CE marked, supporting European safety compliance. Eaton also provides tools to confirm RoHS compliance. When designing for regulated environments, verify local requirements and confirm RoHS status via Eaton’s RoHS search resources prior to procurement.
NOS-80’s non-current-limiting design reduces nuisance trips, translating to lower maintenance and easier fault diagnosis. Its standard packaging and blade-end connections speed replacements, lowering downtime. Consider total cost of ownership over lifecycle by evaluating replacement frequency, stocking levels, and compatibility with existing Bussmann series infrastructure.
