Eaton NOS-110 Fuse - Class H 10 kAIC @ 600V, CE
Part Number: NOS-110
Quick Summary
The Eaton NOS-110 fuse is a general‑purpose Class H device used to protect electrical circuits in industrial control panels. Engineers often wrestle with nuisance trips and inadequate protection when upgrading feeders, which can lead to unexpected downtime. This model carries CE marking and delivers a robust 10 kAIC interrupt rating at 600 V, aligning with common safety and reliability standards. Designed for Bussmann's Class H family, it features a pin‑indicating option to simplify fault diagnosis and fast maintenance. With a 110 A rating and a one‑time fuse design, it provides decisive protection for motors, drives, and power distribution, while its compact 9.63 in length fits standard fuse holders and reduces panel space requirements.

Bussmann series Class H (K) Fuses Data Sheet no. 1030
High current rating and strong interrupt capability translate to meaningful downtime reductions and improved equipment protection in demanding environments. The NOS-110 delivers 110 A protection with a 10 kAIC interrupt rating at 600 V, enabling safer shutdowns for motors, drives, and power distribution within manufacturing lines and process plants. The fuse is non‑current‑limiting (NOS) and designed for general purpose use, balancing reliability with cost, while reducing nuisance tripping on non-critical loads. Its pin‑indicating feature aids quick fault identification during maintenance, improving mean time to repair and minimizing the time panels stay out of service. The Class H classification ensures compatibility with Bussmann series form factors, enabling straightforward replacement and consistent performance across spare parts inventories. The physical dimensions—9.63 in length and 1.84 in width/height—support compact panel layouts and easier integration in dense control cabinets. Packaging is Standard and single‑unit, streamlining procurement and field stocking for service teams.

FAQs
To replace, first power down the equipment and confirm the NOS-110 catalog number is correct for a Bussmann Class H fuse holder. Remove the failed fuse, align the pins with the holder, and insert the NOS-110 so it sits flush and secure. Re-energize and verify operation. Ensure the circuit is within the 600 V rating and 110 A current rating to maintain protection integrity.
The NOS-110 is rated at 110 A with a 10 kAIC interrupt rating at 600 VAC. Its voltage rating is 600 V, making it suitable for general protection in industrial panels and feeders. This pairing supports safe interruption of fault currents while protecting connected equipment, such as motors and drives, without oversizing the protective device.
Yes. The NOS-110 is designed for general-purpose, non-current-limiting protection in electrical control panels and power distribution within industrial environments. It pairs with Bussmann Class H form factors for straightforward replacement, offering reliable protection for critical loads such as automation cabinets, feeders, and small motor circuits, while maintaining compatibility with the Bussmann catalog ecosystem.
NOS-110 carries CE marking, indicating conformity with applicable European safety, health, and environmental protection standards. This aligns with common industry compliance expectations for electrical protection devices used in European and many international installations. Always consult the latest Eaton/Bussmann catalogs for the most up-to-date certification statements and recommended usage guidelines.
Since NOS-110 is a one-time fuse, plan for regular fault-clearance procedures and maintain a stocked inventory of NOS-110 replacements to minimize downtime after faults. The pin‑indicating feature (where available) helps identify a blown fuse quickly, reducing troubleshooting time. Its standardized Bussmann Class H form factor simplifies spares planning and improves maintenance turnaround in high‑throughput environments.
