Eaton NON-1 Fuse - Class H, 1 A, 50 kAIC CE Marked
Part Number: NON-1
Quick Summary
The Eaton NON-1 fuse provides reliable general-purpose protection for control panels and branch circuits in industrial automation. In busy cabinets, nuisance trips can drive maintenance costs and downtime; this non-current-limiting fuse helps maintain uptime by avoiding unnecessary interruptions in simple, fault-tolerant designs. CE marking confirms European safety compliance, and the Class H construction ensures predictable performance in small, high-impedance circuits. The device offers a 1 A rating with a 50 kAIC interrupt capability at both 125 VDC and 250 VAC, making it suitable for mixed AC/DC protection. Its ferrule-end connections and compact footprint support quick installation and scalable panel layouts while preserving Bussmann/Eaton reliability.

FAQs
The NON-1 fuse uses ferrule-end connections compatible with standard fuse blocks and Bussmann/Eaton protection blocks. It suits compact control panels, automation cabinets, and other DIN-rail or fixed-mocket assemblies where ferrule-end fuses are the standard. Ensure the holder accepts Class H, ferrule-end fuses and check the block’s pitch and contact rating for reliable clamping and heat dissipation.
The fuse is rated at 1 A with an interrupt rating of 50 kAIC at 125 Vdc and 50 kAIC at 250 Vac. It uses a 250 Vac / 125 Vdc voltage rating, and is a non-current-limiting Class H fuse. Such specs support reliable protection in mixed AC/DC control circuits while minimizing nuisance trips in simple loads.
Yes. Its 1 A rating, high interrupt capacity, and non-current-limiting behavior make it appropriate for general protection in machine controls and automation panels. It pairs well with ferrule-end block assemblies and is compact enough for dense panel layouts, helping maintain uptime in manufacturing environments.
The NON-1 fuse carries CE Marking, indicating compliance with European safety standards. This is important for any European-installed equipment and industrial systems that require regulatory alignment. While UL/CSA markings are common, this product’s documentation specifies CE compliance and Class H characteristics for coordination in protection schemes.
By reducing nuisance trips through non-current-limiting protection, the NON-1 fuse lowers unnecessary shutdowns and maintenance interventions in simple automation circuits. Its easy ferrule-end installation speeds replacements, and the compact footprint supports scalable panel designs, contributing to lower inventory costs and faster service in high-volume production environments.
