AFS-25 is a specialty fuse designed for the protection of servicing personnel and equipment, and is especially well-suited for protection of high-voltage and/or high-current applications. The AFS-25 fuse is a cylindrical, spring-loaded, open-bolt, current-limiting fuse designed for reliable protection of electrical and electronic equipment and personnel.

The AFS-25 fuse is designed to limit the flow of current through it by controlling the temperature of the fuse element, allowing the fuse to respond quickly to the overcurrent condition. The fuse element is heated by the current flow through it, and when a specific temperature is reached, the element melts and disconnects the circuit, limiting the flow of current.

The AFS-25 fuse has an adjustable current rating that can be set as needed to provide the desired level of overcurrent protection. The working principle of the AFS-25 fuse is based on the fact that the temperature of the element increases with the current flow through it, and when the temperature reaches a specific set point, the element melts and interrupts the circuit. The set point is determined by the amount of current flowing through the fuse, and the design of the fuse element.

The AFS-25 fuse is designed to provide quick and reliable interrupting of the current, and is ideal for use in harsh and extreme environments due to its robust construction. The fuse also has a self-extinguishing design that helps prevent the formation of arcing when the fuse is subjected to extreme temperatures. This self-extinguishing feature helps ensure that the fuse is able to quickly interrupt the current and prevent damage to the circuit.

Due to its reliable current-limiting properties, the AFS-25 is well suited for use in both low and high voltage applications. The fuse is also particularly useful in applications that require reliable and fast current limiting on fault conditions. Additionally, the AFS-25 can be used in applications where continuous high-current carrying capabilities are required, such as the control and protection of motor circuits.

Furthermore, the AFS-25 fuse is designed with a large, extruded aluminum body that provides additional strength and durability. The body is designed to dissipate heat building up in the fuse due to the large currents being passed through it, helping ensure that the fuse does not overheat. The extruded aluminum body also helps keep the fuse from vibrating and moving, helping to ensure a reliable current-limiting protection.

Overall, the AFS-25 fuse is an ideal solution for applications that require reliable and fast current limiting in high voltage and/or high current applications. With its adjustable current rating, robust construction, and large, extruded aluminum body, the AFS-25 fuse provides excellent protection for servicing personnel and equipment alike. Additionally, the fuse’s self-extinguishing design helps prevent the formation of arcing under extreme conditions, thereby ensuring a quick and reliable response to overcurrent conditions.
