FNA-4/10 Description

Short technical summary and product information.

The Eaton Bussmann FNA-4/10 is a cartridge fuse designed for electrical and industrial applications. It is rated for 4mA current at 250VAC and offers a slow blow response time, making it suitable for circuits that experience temporary inrush currents.

 

This fuse features an alarm indicating function, allowing visual indication when the fuse has opened. It has a breaking capacity of 200A at its rated voltage, providing reliable overcurrent protection. The cylindrical package measures 0.406" diameter by 1.500" length (10.31mm x 38.10mm), conforming to the 5AG form factor.

 

The FNA-4/10 requires a separate holder for installation and is approved by CE, CSA, and UL agencies. Its compact size and indicating feature make it practical for panel mounting in industrial control systems.
