Eaton Cartridge Fuse, 1.8A Current Rating, 600V Voltage - FNQ-R-1-8/10


This cartridge fuse provides time-delayed overcurrent protection for control and branch circuits in industrial electrical systems. Designed for use where inrush currents occur, it limits fault energy while allowing temporary surges, making it suitable for protecting small transformers and control electronics in automation and electrical installations.

Features & Benefits


• 200kA interrupt rating protects circuits from high fault currents
• Time-delay response permits harmless inrush without nuisance opening
• Dual-element current-limiting behaviour reduces downstream stress
• Ferrule-to-ferrule termination simplifies installation in cartridge holders
• Non-indicating design removes false Visual diagnostics during operation

**Applications**


• Suitable for protecting small control transformers in panel assemblies
• Ideal for branch-circuit protection in industrial control systems
• Used for safeguarding electronic control modules with inrush currents
• Can be used with rejection-style fuseholders for selective maintenance

What voltage levels can it operate at in industrial systems?


It is rated for operation up to 600V, allowing use across common low-voltage AC distribution and control circuits.

How does the fuse manage surges from motor starts or transformer energisation?


Its time-delay, dual-element construction tolerates temporary overcurrents while activating current-limiting action for sustained faults, thereby reducing prospective let-through energy.

What material is used for the fuse body and why does that matter?


The tube is MADE from melamine, providing electrical insulation and thermal stability suited to panel and control applications.

How quickly will it respond to a small sustained overload at double nominal current?


It is specified to operate in approximately 12s when subjected to 200% of its rated current, allowing a measured response to moderate overloads.
