What is a cartridge fuse?

A cartridge fuse is a replaceable device specifically designed to prevent overcurrent in electric circuits. When the current flowing through the circuit exceeds a predetermined level, the fuse element within the cartridge melts, breaking the circuit and stopping the flow of electricity. This design allows for the easy replacement of the fuse after it has blown, providing a simple and effective means of overcurrent protection.

This type of fuse is generally housed in a cylindrical, cartridge-type casing, which can be quickly replaced when necessary. The characteristics of cartridge fuses make them suitable for various applications, particularly in environments where high levels of reliability are needed, such as in industrial or commercial electrical systems.

Understanding the function and structure of cartridge fuses is essential for recognizing their role in maintaining electrical safety and preventing damage to electrical devices and circuits.
