They consist of a ceramic or glass tube that contains a metal wire or filament which melts when the current exceeds a certain level, breaking the circuit and preventing damage to the system. Cartridge fuses come in a range of sizes and ratings to suit different applications, and are commonly used in residential, commercial and industrial settings. They are easy to install and replace, and provide a reliable and cost-effective solution for protecting electrical equipment and systems.
