Introduction to Screw Fuse
A screw fuse, also known as a plug - in fuse, is a type of electrical fuse that is commonly used in electrical circuits to protect against overcurrent. It consists of a fuse element, usually made of a metal with a low melting point, enclosed in a ceramic or glass body. The screw - in design allows for easy installation and replacement in a fuse holder. When the current flowing through the circuit exceeds the rated value of the fuse, the fuse element melts, breaking the circuit and preventing damage to electrical equipment and potential fire hazards. Screw fuses are widely used in various applications, including residential, commercial, and industrial electrical systems.
