FNM-4 is used for a range of electrical and specialty fuse applications in many industries including Telecommunications, Automotive, Medical, Aerospace, Energy, and Industrial.

Application Fields of FNM-4

FNM-4 is a versatile fuse mainly used for these applications:

• Power Supply & Protection.
• Lighting Circuit & Protection.
• Communication & Technician Protection.
• Computer & Instrument Protection.
• Electric Motor & Control Circuit Protection.
• Home Appliance Protection.
• Automobile & Industrial Control System Protection.
• Other Low Current Electronic Industry Applications.

Working Principle of FNM-4

The FNM-4 fuse is designed with an element made from a conductive material. The element is coiled up and placed in the barrel of the fuse and is kept firmly in contact with the two terminals. When the current passing through the fuse exceeds the rated value for the fuse, the element gets hot. This causes the element to burn and the current is prevented from passing any further.

The FNM-4 fuse also utilizes a chamber filled with inert gas, down the barrel of the fuse. When the fuse is in operation, the inert gas prevents the element from shorting. This prevents accidental tripping of the fuse due to arcing.

Advantages of FNM-4

FNM-4 is a great choice for protecting delicate circuitry because of its reliable features. Some of its advantages include:

• Small yet Reliable: The FNM-4 fuse is relatively small compared to other fuses of the same rating. Its small size makes it perfect for small spaces and hard to reach areas. Despite its size, it provides the same level of protection and reliability.
• Fast Acting: FNM-4 is designed to act quickly in the event of an overload or short-circuit. This helps protect expensive and sensitive electrical equipment from costly damage.
• Good Contact: The FNM-4 fuse has good contact performance, minimizing voltage drop, reducing power losses, and providing superior protection.
• Cost-Effective: FNM-4 is regarded as being cost-effective in comparison to other fuses of the same rating.

Conclusion

FNM-4 is a great choice for those looking for a reliable and cost-effective fuse for low power applications. FNM-4 has a wide range of applications, ranging from power supply and protection to home appliance protection and much more. It is reliable, fast-acting, and provides superior protection to delicate electrical equipment. Overall, FNM-4 is an ideal fuse for low power applications that need superior protection and performance.
