Fuses are safety devices used in electric circuits to provide overcurrent protection. The FWH-12.5A6FR is an auto-reset fuse which can be used in various industrial, military, and automotive applications. This article will discuss the application field and working principle of the FWH-12.5A6FR fuse.

Application Field

The FWH-12.5A6FR auto-reset fuse is designed to intervene in a wide range of applications. It can be used in automotive, industrial, and military applications. It is suitable for safety and overcurrent protection in environments with temperatures between -40°C and 125°C. Its small size and low internal resistance make it an ideal choice for space-restricted designs. Due to its ability to withstand high- pressure conditions, it is suitable for use in harsh industrial environments and harsh climates.

In automotive applications, the FWH-12.5A6FR is suitable for protecting vehicle electrics, including headlights, power windows, and catalytic converters. It can also be used in automotive batteries, starters, and alternators, ensuring that the components are protected from overcurrents. In industrial applications, the auto-reset fuse can be used in automated equipment, including factory automation and assembly line systems, to reduce the risk of system damage.

Working Principle

The FWH-12.5A6FR auto-reset fuse works by allowing current to pass through it until it reaches its rated current. When the rated current is exceeded, the fuse will blow, severing the circuit and interrupting the current flow. When the overcurrent condition is removed, the fuse will reset itself, allowing the circuit to resume its normal operation. This type of fuse is designed to provide overcurrent protection without the need for manual intervention.

The FWH-12.5A6FR is designed to provide superior resistance to vibration, shock, and mechanical wear. Its construction uses a hollow tube of wound stainless-steel wire with silver end caps to provide corrosion resistance. This construction allows the fuse to reduce the power losses of the protected circuits. The low internal resistance ensures that the fuse can hold the current firmly.

The auto-reset fuse is designed to provide a reliable overcurrent protection solution. Its ability to protect against overcurrents without the need for manual intervention makes it ideal for applications that require automatic protection, such as factory automation and assembly line systems. The low power losses of the protected circuits ensure that the system remains safe and efficient.

In conclusion, the FWH-12.5A6FR is an auto-reset fuse suitable for a wide range of applications in automotive, industrial, and military applications. It works by allowing current to pass through it until it reaches its rated current, at which point it will blow, severing the circuit and interrupting the current flow. It is designed to provide superior resistance to vibration, shock, and mechanical wear, and its low internal resistance ensures that the fuse can hold the current firmly. Its ability to protect against overcurrents without the need for manual intervention makes it an ideal choice for applications that require automatic protection.
