Eaton NOS-100 Fuse - Class H 10 kAIC at 600 Vac
Part Number: NOS-100
Quick Summary
The Eaton NOS-100 fuse provides reliable protection for general electrical circuits in industrial control panels. Engineers often struggle with nuisance trips and downtime caused by misapplied protection or slow fault clearance. CE marking supports European safety requirements while the Class H design and a 10 kAIC interrupt rating ensure fast, predictable interruptions under fault conditions. For panel builders and maintenance teams, selecting a standard, readily available fuse like NOS-100 reduces spare-part inventory and procurement lead times, delivering consistent performance in 600 V systems. This combination of robust protection and convenient procurement translates to lower maintenance costs and improved plant availability in demanding environments.

FAQs
NOS-100 uses blade-end x blade-end connections and a standard 7.9 inch length to fit common fuse blocks. Ensure your panel provides blade-type fuse holders rated for 600 V and 100 A. Verify fitment with the enclosure’s allowable dimensions and check that the holder supports non-indicating indicators if visual confirmation is required during maintenance.
NOS-100 is a 100 A Class H fuse with a 10 kAIC interrupt rating at 600 Vac. It is a general-purpose, non-current-limiting fuse designed for reliable protection in 600 V circuits, suitable for industrial control and distribution applications.
NOS-100 is intended as a general-purpose protection device in industrial panels. While it can protect motor control circuits connected to 600 V systems, motor protection often requires dedicated motor-rated fuses or protection schemes tailored to inrush and continuous motor loading. Always confirm compatibility with motor starting current and enclosure requirements.
NOS-100 carries CE marking, indicating compliance with European safety standards. The listing also notes standard packaging and general compliance features; always verify project-specific regulatory requirements and supplier documentation for additional certifications as needed.
NOS-100 comes in a convenient 5-pack, reducing stocking complexity and procurement cycles. Its 7.9 in length and standardized blade-end design simplify installation and replacements, while the high 10 kAIC interrupt rating minimizes downtime and equipment damage during faults, delivering measurable ROI in reliability-driven projects.
