What are the two main types of fuses?

The two main types of fuses are plug fuses and cartridge fuses. Plug fuses are designed to be inserted directly into a socket and have a simple installation process, typically employed in residential applications. They provide overcurrent protection by melting a fuse element when excessive current flows through, interrupting the circuit.

On the other hand, cartridge fuses are cylindrical and typically require a fuse holder for installation. They are commonly used in higher voltage and more industrial applications due to their design and capacity to withstand higher currents and provide better reliability.

The distinction between these two types is important, as they cater to different applications and electrical system requirements. Understanding the characteristics and appropriate usage of both plug and cartridge fuses enables electricians to select the proper type of fuse for a given situation, ensuring effective and reliable overcurrent protection.
